- Subject: Options on Stocks
- From: ask@cbnews.cb.att.com
-
- First, an option is a contract between buyer and seller.
-
- The option is connected to something, such as a listed stock or an
- exchange index or futures contracts or real estate. For simplicity,
- I will discuss only options connected to listed stocks.
-
- The option is designated by:
- - Name of the associated stock
- - "strike price"
- - Expiration Date
-
- - The option costs a "premium" to buy, plus brokers commission.
-
- The two most popular types of options are Calls and Puts.
-
- Example: The Wall Street Journal might list an
- IBM Oct 90 Call @ $2.00
-
- Translation: This is a Call Option
-
- The company associated with it is IBM
- (See also the price of IBM stock on the NYSE)
-
- The option expires on the third Saturday
- following the third Friday of October, 1992.
- (an option is worthless and useless once it expires)
-
- The strike price is $90.00 If you own this option
- you can buy IBM @ $90.00, even if it is then trading on
- the NYSE @$100.00 (I should be so lucky!)
-
- If you want to buy the option it will cost you $2.00
- plus brokers commissions. If you want to sell
- the option you will get $2.00 less commissions.
-
- In general, options are written on blocks of 100s of shares. So when
- you buy "1" IBM Oct 90 Call @ $2.00 you actually are buying a contract
- to buy 100 shares of IBM @ $90 per share ($9,000) on or before the
- expiration date in October. You will pay $200 plus commission to buy
- the call.
-
- If you wish to exercise your option you call your broker and say you
- want to exercise your option. Your broker will arrange for the person
- who sold you your option ( a financial fiction: A computer matches up
- buyers with sellers in a magical way) to sell you 100 shares of IBM for
- $9,000 plus commission.
-
- If you instead wish to sell (sell=write) that option you instruct your
- broker that you wish to write 1 Call IBM Oct 90s, and the very next day
- your account will be credited with $200 less commission.
-
- If IBM does not reach $90 before the call expires, the option writer
- gets to keep that $200 (less commission) If the stock does reach above
- $90, you will probably be "called."
-
- If you are called you must deliver the stock. Your broker will sell
- your IBM stock for $9000 (and charge commission). If you owned the
- stock, that's OK. If you did not own the stock your broker will buy the
- stock at market price and immediately sell it at $9000. Commissions
- each way.
-
- If you write a Call option and own the stock that's called "Covered
- Call Writing." If you don't own the stock it's called "Naked Call
- Writing." It is quite risky to write naked calls, since the price of
- the stock could zoom up and you would have to buy it at the market price.
-
- My personal advice for new options people if to begin by writing
- covered call options for stocks currently trading below the strike
- price of the option (write out-of-the-money covered calls).
-
- When the strike price of a call is above the current market price of
- the associated stock, the call is "out of the money" and is "in
- the money" when the stock price is below the call's strike price.
-
- Most regular folks like you and me do not exercise our options; we
- trade them back, covering our original trade. Saves commissions and
- all that.
-
- The other common option is the PUT. If you buy a put from me, you
- gain the right to sell me your stock at the strike price on or before
- the expiration date. Puts are almost the mirror-image of calls.
-
- -----------------------------------------------------------------------------
-
- Subject: P/E Ratio
- From: egreen@east.sun.com, schindler@csa2.lbl.gov
-
- P/E is shorthand for Price/Earnings Ratio. The price/earnings ratio is
- a tool for determining the value the market has placed on a common stock.
- A lot can be said about this little number, but in short, companies
- expected to grow and have higher earnings in the future should have a
- higher P/E than companies in decline. For example, if Amgen has a lot
- of products in the pipeline, I wouldn't mind paying a large multiple of
- its current earnings to buy the stock. It will have a large P/E. I am
- expecting it to grow quickly.
-
- P/E is determined by dividing the current market price of one share
- of a company's stock by that company's per-share earnings (after-tax
- profit divided by number of outstanding shares). For example, a company
- that earned $5M last year, with a million shares outstanding, had
- earnings per share of $5. If that company's stock currently sells for
- $50/share, it has a P/E of 10. Investors are willing to pay $10 for
- every $1 of last year's earnings.
-
- P/Es are traditionally computed with trailing earnings (earnings from
- the year past, called a trailing P/E) but are sometimes computed with
- leading earnings (earnings projected for the year to come, called a
- leading P/E). Like other indicators, it is best viewed over time,
- looking for a trend. A company with a steadily increasing P/E is being
- viewed by the investment community as becoming more and more speculative.
-
- PE is a much better comparison of the value of a stock than the price.
- A $10 stock with a PE of 40 is much more "expensive" than a $100 stock
- with a PE of 6. You are paying more for the $10 stock's future earnings
- stream. The $10 stock is probably a small company with an exciting product
- with few competitors. The $100 stock is probably pretty staid - maybe a
- buggy whip manufacturer.

- Subject: Renting vs. buying a place to live
- From: mincy@think.com, lott@informatik.uni-kl.de
-
- This note will explain one way to compare the monetary costs of renting
- vs. buying a home. It is extremely predjudiced towards the US system.
-
- SUMMARY:
- - If you are guaranteed an appreciation rate that is a few points above
- inflation, buy.
- - If the monthly costs of buying are basically the same as renting, buy.
- - The shorter the term, the more advantageous it is to rent.
- - Tax consequences in the US are insignificant.
-
-
- The three important factors that affect the analysis the most:
- 1) Relative cash flows; e.g., rent compared to monthly ownership expenses
- 2) Length of term
- 3) Rate of appreciation
-
- The approach used here is to determine the present value of the money
- you will pay over the term for the home. In the case of buying, the
- appreciation rate and thereby the future value of the home is estimated.
- This analysis neglects utility costs because they can easily be the
- same whether you rent or buy. However, adding them to the analysis
- is simple; treat them the same as the costs for insurance in both cases.
-
- Computation of present value is reasonably straightforward and is explained
- elsewhere. Programs to compute present and future value as well as for loan
- amortization (pv, fv, loan) are also available from Lott.
-
- Opportunity costs of buying are effectively captured by the present value.
- For example, pretend that you are able to buy a house without having to
- have a mortgage. Now the question is, is it better to buy the house with
- your hoard of cash or is it better to invest the cash and continue to rent.
- To answer this question you have to have estimates for rental costs and
- house costs (see below), and you have a projected growth rate for the cash
- investment and projected growth rate for the house. If you project a 4%
- growth rate for the house and a 15% growth rate for the cash then holding
- the cash would be a much better investment.
-
-
- Renting a Home.
-
- * Step 1: Gather data. You will need:
- - monthly rent
- - renter's insurance (usually inexpensive)
- - term (period of time over which you will rent)
- - estimated inflation rate to compute present value (historically 4.5%)
- - estimated annual rate of increase in the rent (can use inflation rate)
-
- * Step 2: Compute the present value of the cash stream that you will pay over
- the term, which is the cost of renting over that term. This analysis assumes
- that there are no tax consequences (benefits) associated with paying rent.
- (The 'pv' program can help here.)
-
- Long-term example:
- Rent = 990 / month
- Insurance = 10 / month
- Term = 30 years
- Rent increases = 4.5% annually
- Inflation = 4.5% annually
- For this cash stream, present value = 348,137.17.
-
- Short-term example:
- Same numbers, but just 2 years. Present value = 23,502.38
-
-
- Buying a Home.
-
- * Step 1: Gather data. You need a lot to do a fairly thorough analysis:
- - purchase price
- - down payment & closing costs
- - other regular expenses, such as condo fees
- - amount of mortgage
- - mortgage rate
- - mortgage term
- - mortgage payments (this is tricky for a variable-rate mortgage)
- - property taxes
- - homeowner's insurance
- - your tax bracket
- - the current standard deduction you get
- Other values have to be estimated, and they affect the analysis critically:
- - continuing maintenance costs (I estimate 1/2 of PP over 30 years.)
- - estimated inflation rate to compute present value (historically 4.5%)
- - rate of increase of property taxes, maintenance costs, etc. (infl. rate)
- - appreciation rate of the home (THE most important number of all)
-
- * Step 2: compute the monthly expense. This includes the mortgage payment,
- fees, property tax, insurance, and maintenance. The mortgage payment is
- fixed, but you have to figure inflation into the rest. Then compute the
- present value of the cash stream. (The 'pv' program can help.)
-
- * Step 3: compute your tax savings. Roughly you should multiply your tax
- bracket times the amount by which your interest plus property tax expenses
- exceeds your standard deduction. No fair using the whole amount because
- everyone gets the standard deduction for free. Must be summed over the
- term because the standard deduction will increase annually, as will your
- property taxes. Note that late in the mortgage your interest payments will
- be be well below the standard deduction. I compute savings of about 5%.
- (The 'loan' program can help.)
-
- * Step 4: compute the future value of the home based on the purchase
- price, estimated appreciation rate, and the term. Once you have the
- future value, compute the present value of that sum based on the
- inflation rate you estimated earlier and the term you used to compute
- future value. If appreciation > inflation, you win. Else you lose.
- (The 'pv' and 'fv' programs can help.)
-
- * Step 5: Compute final cost. All numbers must be in present value.
- Final-cost = Down-payment + S2 (expenses) - S3 (tax sav) - S4 (prop value)
-
- Long-term example #1:
-
- * Step 1 - the data:
- Purchase price = 145,000
- Down payment etc = 10,000
- Mortgage amount = 140,000
- Mortgage rate = 8.00%
- Mortgage term = 30 years
- Mortgage payment = 1027.27 / mo
- Property taxes = about 1% of valuation; I'll use 1200/yr = 100/mo
- (which increases same as inflation, we'll say)
- Homeowner's ins = 50 / mo
- Condo fees etc = 0
- Tax bracket = 33%
- Standard ded = 5600
- Estimates:
- Maintenance = 1/2 PP is 72,500, or 201/mo; I'll use 200/mo
- Inflation rate = 4.5% annually
- Prop taxes incr = 4.5% annually
- Home appreciates = 6% annually (the NUMBER ONE critical factor)
-
- * Step 2 - the monthly expense, both fixed and changing components:
- Fixed component is the mortgage at 1027.27 monthly. Present value = 203,503.48
- Changing component is the rest at 350.00 monthly. Present value = 121,848.01
- Total from Step 2: 325,351.49
-
- * Step 3 - the tax savings.
- I use my loan program to compute this. Based on the data given above,
- I compute the savings: Present value = 14,686.22. Not much at all.
-
- * Step 4 - the future and present value of the home.
- See data above. Future value = 873,273.41 and present value = 226,959.96
- (which is larger than 145k since appreciation > inflation)
- Before you compute present value, you should subtract reasonable closing
- costs for the sale; for example, a real estate brokerage fee.
-
- * Step 5 - the final analysis for 6% appreciation.
- Final = 10,000 + 325,351.49 - 14,686.22 - 226,959.96
- = 93,705.31
-
- So over the 30 years, assuming that you sell the house in the 30th year for
- the estimated future value, the present value of your total cost is 93k.
- (You're 93k in the hole after 30 years ~~ you only paid 260.23/month.)
-
- Long-term example #2: all numbers the same BUT the home appreciates 7%/year.
- Step 4 now comes out FV=1,176,892.13 and PV=305,869.15
- Final = 10,000 + 325,351.49 - 14,686.22 - 305,869.15
- = 14796.12
- So in this example, 7% was an approximate break-even point in the absolute
- sense; i.e., you lived for 30 years at near zero cost in today's dollars.
-
- Long-term example #3: all numbers the same BUT the home appreciates 8%/year.
- Step 4 now comes out FV=1,585,680.80 and PV=412,111.55
- Final = 10,000 + 325,351.49 - 14,686.22 - 412,111.55
- = -91,446.28
- The negative number means you lived in the home for 30 years and left it in
- the 30th year with a profit; i.e., you were paid to live there.
-
- Long-term example #4: all numbers the same BUT the home appreciates 2%/year.
- Step 4 now comes out FV=264,075.30 and PV=68,632.02
- Final = 10,000 + 325,351.49 - 14,686.22 - 68,632.02
- = 252,033.25
- In this case of poor appreciation, home ownership cost 252k in today's money,
- or about 700/month. If you could have rented for that, you'd be even.
-
- Short-term example #1: all numbers the same as Long-term example #1, but you
- sell the home after 2 years. Future home value in 2 years is 163,438.17
- Cost = down&cc + all-pymts - tax-savgs - pv(fut-home-value - remaining debt)
- = 10,000 + 31,849.52 - 4,156.81 - pv(163438.17 - 137,563.91)
- = 10,000 + 31,849.52 - 4,156.81 - 23651.27
- = 14,041.44
-
- Short-term example #2: all numbers the same as Long-term example #4, but you
- sell the home after 2 years. Future home value in 2 years is 150,912.54
- Cost = down&cc + all-pymts - tax-savgs - pv(fut-home-value - remaining debt)
- = 10,000 + 31,849.52 - 4,156.81 - pv(150912.54 - 137,563.91)
- = 10,000 + 31,849.52 - 4,156.81 - 12,201.78
- = 25490.93
-
-
- Some closing comments:
-
- Once again, the three important factors that affect the analysis the most
- are cash flows, term, and appreciation. If the relative cash flows are
- basically the same, then the other two factors affect the analysis the most.
-
- The longer you hold the house, the less appreciation you need to bet renting.
- This relationship always holds, however, the scale changes. For shorter
- holding periods you also face a risk of market downturn. If there is a
- substantial risk of a market downturn you shouldn't buy a house unless you
- are willing to hold the house for a long period.
-
- If you have a nice cheap rent controlled appartment, then you should probably
- not buy.
-
- There are other variables that affect the analysis, for example, the inflation
- rate. If the inflation rate increases, the rental scenario tends to get much
- worse, while the ownership scenario tends to look better.
-
- Question: Is it true that you can usually rent for less than buying?
-
- Answer 1: It depends. It isn't a binary state. It is a fairly complex set
- of relationships.
-
- In large metropolitan areas, where real estate is generally much more expensive
- then it is usually better to rent, unless you get a good appreciation rate or
- if you are going to own for a long period of time. It depends on what you can
- rent and what you can buy. In other areas, where real estate is relatively
- cheap, I would say it is probably better to own.
-
- On the other hand, if you are currently at a market peak and the country is
- about to go into a recession it is better to rent and let property values and
- rent fall. If you are currently at the bottom of the market and the economy
- is getting better then it is better to own.
-
- Answer 2: When you rent from somebody, you are paying that person to assume
- the risk of homeownership. Landlords are renting out property with the long
- term goal of making money. They aren't renting out property because they want
- to do their renters any special favors. This suggests to me that it is
- generally better to own.

- Subject: Shorting Stocks
- From: ask@cblph.att.com
-
- Shorting means to sell something you don't own.
-
- If I do not own shares of IBM stock but I ask my broker to sell short
- 100 shares of IBM I have committed shorting. In broker's lingo, I
- have established a short position in IBM of 100 shares. Or, to really
- confuse the language, I hold 100 shares of IBM short.
-
- Why would you want to short?
-
- Because you believe the price of that stock will go down, and you can
- soon buy it back at a lower price than you sold it at. When you buy
- back your short position, you "close your short position."
-
- The broker will effectively borrow those shares from another client's
- account or from the broker's own account, and effectively lend you
- the shares to sell short. This is all done with mirrors; no stock
- certificates are issued, no paper changes hands, no lender is identified
- by name.
-
- My account will be credited with the sales price of 100 shares of IBM
- less broker's commission. But the broker has actually lent me the stock
- to sell; no way is he going to pay interest on the funds from the short
- sale. (Exception: Really big spenders sometimes negotiate a full or
- partial payment of interest on short sales funds provided sufficient
- collateral exists in the account and the broker doesn't want to lose
- the client. If you're not a really big spender, don't expect to receive
- any interest on the funds obtained from the short sale.) Also expect
- the broker to make you put up additional collateral. Why?
-
- Well, what happens if the stock price goes way up? You will have to
- assure the broker that if he needs to return the shares whence he got
- them (see "mirrors" above) you will be able to purchase them and "close
- your short position." If the price has doubled, you will have to spend
- twice as much as you received. So your broker will insist you have
- enough collateral in your account which can be sold if needed to close
- your short position. More lingo: Having sufficient collateral in your
- account that the broker can glom onto at will, means you have "cover"
- for your short position. As the price goes up you must provide more cover.
-
- Since you borrowed these shares, if dividends are declared, you will be
- responsible for paying those dividends to the fictitious person from
- whom you borrowed. Too bad.
-
- Even if you hold you short position for over a year, your capital
- gains are short term.
-
- A short squeeze can result when the price of the stock goes up. When
- the people who have gone short buy the stock to cover their previous
- short-sales, this can cause the price to rise further. It's a death
- spiral - as the price goes higher, more shorts feel driven to cover
- themselves, and so on.
-
- You can short other securities besides stock. For example, every time
- I write (sell) an option I don't already own long, I am establishing a
- short position in that option. The collateral position I must hold in
- my account generally tracks the price of the underlying stock and not
- the price of the option itself. So if I write a naked call option on
- IBM November 70s and receive a mere $100 after commissions, I may be
- asked to put up collateral in my account of $3,500 or more! And if
- in November IBM has regained ground and is at $90 [ I should be so
- lucky ], I would be forced to buy back (close my short position in
- the call option) at a cost of about $2000, for a big loss.
-
- Selling short is seductively simple. Brokers get commissions by
- showing you how easy it is to generate short term funds for your
- account, but you really can't do much with them. My personal advice
- is if you are strongly convinced a stock will be going down, buy the
- out-of-the-money put instead, if such a put is available.
-
- A put's value increases as the stock price falls (but decreases sort
- of linearly over time) and is strongly leveraged, so a small fall in
- price of the stock translates to a large increase in value of the put.
-
- Let's return to our IBM, market price of 66 (yuck.) Let's say I strongly
- believe that IBM will fall to, oh, 58 by mid-November. I could short
- IBM stock at 66, sell it at 58 in mid-November if I'm right, and make
- about net $660. If instead it goes to 70, and I have to sell then I
- lose net $500 or so. That's a 10% gain or an 8% loss or so.
-
- Now, I could buy the IBM November 65 put for maybe net $200. If it
- goes down to 58 in mid November, I sell (close my position) for about
- $600, for a 300% gain. If it doesn't go below 65, I lose my entire
- 200 investment. But if you strongly believe IBM will go way way down,
- you should shoot for the 300% gain with the put and not the 10% gain
- by shorting the stock itself. Depends on how convinced you are.
-
- Having said this, I add a strong caution: Puts are very risky, and
- depend very much on odd market behavior beyond your control, and you
- can easily lose your entire purchase price fast. If you short options,
- you can lose even more than your purchase price!
-
- One more word of advice. Start simply. If you never bought stock
- start by buying some stock. When you feel like you sort of understand
- what you are doing, when you have followed several stocks in the
- financial section of the paper and watched what happens over the course
- of a few months, when you have read a bit more and perhaps seriously
- tracked some important financials of several companies, you might --
- might -- want to expand your investing choices beyond buying stock.
- If you want to get into options (see FAQ on options) start with writing
- covered calls. I would place selling stock short or writing or buying
- other options lower on the list -- later in time.

- Subject: Stock Index Types
- From: susant@usc.edu
-
- There are three major classes of indices in use today in the US. They are:
-
- A - equally weighted price index
- (an example is the Dow Jones Industrial Average)
- B - market-capitalization-weighted index
- (an example is the S&P Industrial Average)
- C - equally-weighted returns index
- (the only one of its kind is the Value-Line index)
-
- Of these, A and B are widely used. All my profs in the business school
- claim that C is very weird and don't emphasize it too much.
-
- + Type A index: As the name suggests, the index is calculated by taking the
- average of the prices of a set of companies:
-
- Index = Sum(Prices of N companies) / divisor
-
- In this calculation, two questions crop up:
-
- 1. What is "N"? The DJIA takes the 30 large "blue-chip" companies. Why 30?
- I think it's more a historical hangover than any thing else. One rationale
- for 30 might be that a large fraction of market capitalization is often
- clustered in largest 50 companies or so.
-
- Does the set of N companies change across time? If so, how often is the
- list updated (wrt companies)? I suspect these decisions are quite
- judgemental and hence not readily replicable.
-
- If the DJIA only has 30 companies, how do we select these 30? Why should
- they have equal weights? These are real criticisms of the DJIA type index.
-
- 2. The divisor is not always equal to N for N companies. What happens to
- the index when there is a stock issue by one of the companies in the set?
- The price drops, but the number of shares have increased to leave the market
- capitalization of the shares the same. Since the index does not take the
- latter into account, it has to compensate for the drop in price by tweaking
- the divisor. For examples on this, look at pg. 61 of Bodie, Kane, & Marcus,
- _Investments_ (henceforth, BKM).
-
- Historically, this index format was computationally convenient. It doesn't
- have a very sound economic basis to justify it's existence today. The DJIA
- is widely cited on the evening news, but not used by real finance folks.
-
- I have an intuition that the DJIA type index will actually be BAD if the
- number of companies is very large. If it's to make any sense at all, it
- should be very few "brilliantly" chosen companies.
-
- + Type B index: In this index, each of the N company's price is weighted by
- the market capitalization of the company.
-
- Sum (Company market capitalization * Price) over N companies
- Index = ------------------------------------------------------------
- Market capitalisation for these N companies
-
- Here you do not take into account the dividend data, so effectively you're
- tracking the short-run capital gains of the market.
-
- Practical questions regarding this index:
-
- 1. What is "N"? I would use the largest N possible to get as close to the
- "full" market as possible. BTW in the US there are companies who make a
- living on only calculating extremely complete value-weighted indexes for
- the NYSE and foreign markets. CMIE should sell a very-complete value-weighted
- index to some such folks.
-
- Why does S&P use 500? Once again, I'm guessing that it's for historical
- reasons when computation over 20,000 companies every day was difficult and
- because of the concentration of market capitalization in the largest lot
- of companies. Today, computation over 20k companies for a Sun workstation
- is no problem, so the S&P idea is obsolete.
-
- 2. How to deal with companies entering and exiting the index? If we're
- doing an index containing "every single company possible" then the answer
- to this question is easy -- each time a company enters or exits we recalculate
- all weights. But if we're a value-weighted index like the S&P500 (where there
- are only 500 companies) it's a problem. Recently Wang went bankrupt and S&P
- decided to replace them by Sun -- how do you justify such choices?
-
- The value weighted index is superior to the DJIA type index for deep reasons.
- Anyone doing modern finance will not use the DJIA type index. A glimmer of
- the reasoning for this is as follows: If I held a portfolio with equal number
- of shares of each of the 30 DJIA companies then the DJIA index would accurately
- reflect my capital gains. BUT we know that it is possible to find a portfolio
- which has the same returns as the DJIA portfolio but at a smaller risk.
- (This is a mathematical fact).
-
- Thus, by definition, nobody is ever going to own a DJIA portfolio. In
- contrast, there is a extremely good interpretation for the value weighted
- portfolio -- it's the highest returns you can get for it's level of risk.
- Thus you would have good reason for owning a value-weighted market portfolio,
- thus justifying it's index.
-
- Yet another intuition about the value-weighted index -- a smart investor is
- not going to ever buy equal number of shares of a given set of companies,
- which is what index type a. tracks. If you take into consideration that the
- price movements of companies are correlated with others, you are going to
- hedge your returns by buying different proportions of company shares. This
- is in effect what the index type B does and this is why it is a smarter index
- to follow.
-
- One very neat property of this kind of index is that it is readily applied to
- industry indices. Thus you can simply apply the above formula to all machine
- tool companies, and you get a machine tool index. This industry-index is
- conceptually sound, with excellent interpretations. Thus on a day when the
- market index goes up 6%, if machine tools goes up 10%, you know the market
- found some good news on machine tools.
-
- + Type C index: Here the index is the average of the returns of a certain
- set of companies. Value Line publishes two versions of it:
-
- * the arithmetic index : (VLAI/N) = 1 * Sum(N returns)
- * the geometric index : VLGI = {Product(1 + return) over N}^{1/n},
- which is just the geometric mean of the N returns.
-
- Notice that these indices imply that the dollar value on each company has
- to be the same. Discussed further in BKM, pg 66.

-
- The Dow Jones averages are computed by summing the prices of the stocks
- in the average and then dividing by a constant called the "divisor". The
- divisor for the industrial average is adjusted periodically to reflect
- splits in the stocks making up the average; the divisor was originally 30
- but has been reduced over the years to 0.462685 (as of 92-10-31). The
- current value of the divisor can be found in the Wall Street Journal

-
- Standard & Poor's 500: 500 of the biggest US corporations.
- This is a very popular institutional index, and recently becoming
- more popular among individuals. Most often used measure of broad
- stock market results.
- Wilshire 5000
- Includes most publicly traded shares. Considered by some a better
- measure of market as a whole, becuase it includes smaller companies.
- Wilshire 4500
- These are all firms *except* the S&P 500.
- Value Line Composite
- See Martin Zweig's Winning on Wall Street for a good description.
- It is a price-weighted index as opposed to a capitalization index.
- Zweig (and others) think this gives better tracking of investment
- results, since it is not over-weighted in IBM, for example, and
- most individuals are likewise not weighted by market cap in their
- portfolios (unless they buy index funds).
- Nikkei Dow (Japan)
- I believe "Dow" is a misnomer. It is called the Nikkei index (or
- the Nikkei-xx, where xx is the number of shares in it, which I
- can't quote to you out of my head). "Dow" comes from Dow Jones &
- Company, which publishes DJIA numbers. Nikkei is considered the
- "Japanese Dow," in that it is the most popular and commonly quoted
- Japanese market index, but I don't think Dow Jones owns it.
- S&P 100 (and OEX)

- Subject: Stock Splits
- From: egreen@east.sun.com, schindler@csa2.lbl.gov, ask@cblph.att.com
-
- Ordinary splits occur when the company distributes more stock to holders
- of existing stock. A stock split, say 2-for-1, is when a company simply
- issues two shares for every one outstanding. If the stock was at $50
- per share, after the split, each share is worth $25, because the company's
- net assets didn't increase, only the number of outstanding shares.
-
- Sometimes an ordinary split is referred to as a percent. A 2:1 split is
- a 100% stock split (or 100% stock dividend). A 50% split would be a 3:2
- split (or 50% stock dividend). You will get 1 more share of stock for
- every 2 shares you owned.
-
- Reverse splits occur when a company wants to raise the price of their
- stock, so it no longer looks like a "penny stock" but looks more like a
- self-respecting stock. Or they might want to conduct a massive reverse
- split to eliminate small holders. If a $1 stock is split 1:10 the new
- shares will be worth $10. Holders will have to trade in their 10 Old
- Shares to receive 1 New Share.
-
- Often a split is announced long before the effective date of the split,
- along with the "record date." Shareholders of record on the record
- date will receive the split shares on the effective date (distribution
- date). Sometimes the split stock begins trading as "when issued" on or
- about the record date. The newspaper listing will show both the pre-
- split stock as well as the when-issued split stock with the suffix "wi."
- (Stock dividends of 10% or less will generally not trade wi.)
-
- Theoretically a stock split is a non-event. The fraction of the company
- each of your shares represents is reduced, but you are given enough
- shares so that your total fraction of the company owned remains the same.
- On the day of the split, the value of the stock is also adjusted so that
- the total capitalization of the company remains the same.
-
- In practice, an ordinary split often drives the new price per share up,
- as more of the public is attracted by the lower price. A company might
- split when it feels its per-share price has risen beyond what an individual
- investor is willing to pay, particularly since they are usually bought
- and sold in 100's. They may wish to attract individuals to stabilize the
- price, as institutional investors buy and sell more often than individuals.

- Subject: Ticker Tape Terminology
- From: capskb@alliant.backbone.uoknor.edu, nfs@cs.princeton.edu
-
- Ticker tape says: Translation (but see below):
- NIKE68 1/2 100 shares sold at 68 1/2
- 10sNIKE68 1/2 1000 shares sold at "
- 10.000sNIKE68 1/2 10000 shares sold at "
-
- The extra zeroes for the big trades are to make them stand out. All
- trades on CNN and CNBC are delayed by 15 minutes. CNBC once advertised
- a "ticker guide pamphlet, free for the asking", back when they merged
- with FNN. It also has explanations for the futures they show.
-
- However, the first translation is not necessarily correct. CNBC has
- a dynamic maximum size for transactions that are displayed this way.
- Depending on how busy things are at any particular time, the maximum
- varies from 100 to 5000 shares. You can figure out the current maximum
- by watching carefully for about five minutes. If the smallest number
- of shares you see in the second format is "10s" for any traded security,
- then the first form can mean anything from 100 to 900 shares. If the
- smallest you see is "50s" (which is pretty common), the first form
- means anything between 100 and 4900 shares.
-
- Note that at busy times, a broker's ticker drops the volume figure and
- then everything but the last dollar digit (e.g. on a busy day, a trade
- of 25,000 IBM at 68 3/4 shows only as "IBM 8 3/4" on a broker's ticker).
- That never happens on CNBC, so I don't know how they can keep up with all
- trades without "forgetting" a few.

- Subject: Treasury Direct
- From: jberlin@falcon.aamrl.wpafb.af.mil
-
- You can buy T-Bills directly from the US Treasury. Contact any Federal
- Reserve Bank and ask for information on Treasury Direct. The minimum
- for a Treasury Note (2 years and up) is only $5K and in some instances
- (I believe 5 year notes) $1K. There are no fees and you may elect to
- have interest payments made directly to your account. You even may pay
- with a personal check, no need for a cashier's or certified check as
- Treasury Bills (1 year and under) required. AAII Journal had an article
- on this a couple of years ago. Like they said, the government service is

-
- Subject: Uniform Gifts to Minors Act (UGMA)
- From: ask@cbnews.cb.att.com, schindler@csa1.lbl.gov
-
- The Uniform Gifts to Minors Act allows you to give $10,000 per year
- to any minor, tax free. You must appoint a custodian.
-
- Some accountants advise that one person should make the gift and
- that a different person should be the custoidian, but I have never
- seen any IRS publication to justify this, nor any tax case ruling
- which makes this a problem. I suspect some people are just being
- conservative.
-
- To give such a gift, go to your friendly neighborhood stockbroker,
- bank, mutual fund manager, or (close your eyes now: S&L), etc. and
- say that you wish to open a Uniform Gifts (in some states "Transfers")
- to Minors Act account.
-
- You register it as:
- [ Name of Custodian ] as custodian for [ Name of Minor ] under the
- Uniform Gifts/Transfers to Minors Act - [ Name of State of Minor's
- residence ]
-
- You use the minor's social security number as the taxpayer ID for this
- account. When you fill out the W-9 form for this account, it will
- show this form. The custodian should certify the W-9 form.
-
- The money now belongs to the minor and the custodian has a legal
- fiduciary responsibility to handle the money in a prudent manner for
- the benefit of the minor.
-
- So you can buy common stocks but cannot write naked options. You
- cannot "invest" the money on the horses, planning to donate the
- winnings to the minor. And when the minor reaches age of majority -
- usually 18 - the minor can claim all of the funds even if that's
- against your wishes. You cannot place any conditions on those funds
- once the minor becomes an adult.
-
- Until the minor reaches 14, the first $500 earned by the minor is
- tax free, the next $500 is taxed at the minor's rate, and the rest
- is taxed at the higher of the minor's or the parent's rate. After
- the minor reaches 14, all earnings over $500 are taxed at the
- minor's rate.
-
- Note that if you want to continue doing your childs taxes even after
- they turn 18, there is no reason they need to know about their UGMA
- account that you set up for them. They certainly can't blow their
- college fund on a Trans Am if they don't know about it.
-
- Even if your child does his/her own taxes, you can still give them
- gifts through a trust without them knowing about it until they are
- more mature. Call and ask Twentieth Century Investors for information
- about their GiftTrust fund. The fund is entirely composed of trusts
- like this. The trust pays its own taxes.

- Subject: Warrants
- From: ask@cblph.att.com
-
- There are many meanings to the word warrant.
-
- The marshal can show up on your doorstep with a warrant for your arrest.
-
- Many army helicopter pilots are warrant officers, who have received
- a warrant from the president of the US to serve in the Army of the
- United States.
-
- The State of California ran out of money earlier this year and
- issued things that looked a lot like checks, but had no promise to
- pay behind them. If I did that I could be arrested for writing a
- bad check. When the State of California did it, they called these
- thingies "warrants" and got away with it.
-
- And a warrant is also a financial instrument which was issued with
- certain conditions. The issuer of that warrant sets those conditions.
- Sometimes the warrant and common or preferred convertible stock are
- issued by a startup company bundled together as "units" and at some
- later date the units will split into warrants and stock. This is a
- common financing method for some startup companies. This is the
- "warrant" most readers of the misc.invest newsgroup ask about.
-
- As an example of a "condition," there may be an exchange privilege
- which lets you exchange 1 warrant plus $25 in cash (or even no cash
- at all) for 100 shares of common stock in the corporation, any time
- after some fixed date and before some other designated date.
- (And often the issuer can extend the "expiration date.")
-
- So there are some similarities between warrants and call options for
- common stock.
-
- Both allow holders to exercise the warrant/option before an
- expiration date, for a certain number of shares. But the option is
- issued by independent parties, such as a member of the Chicago Board
- Options Exchange, while the warrant is issued and guaranteed by the
- corporate issuer itself. The lifetime of a warrant is often
- measured in years, while the lifetime of a call option is months.
-
- Sometimes the issuer will try to establish a market for the warrant,
- and even try to register it with a listed exchange. The price can
- then be obtained from any broker. Other times the warrant will be
- privately held, or not registered with an exchange, and the price
- is less obvious, as is true with non-listed stocks.
-

-
- Subject: Zero-Coupon Bonds
- From: ask@cblph.att.com
-
- Not too many years ago every bond had coupons attached to it. Every
- so often, usually every 6 months, bond owners would take a scissors
- to the bond, clip out the coupon, and present the coupon to the bond
- issuer or to a bank for payment. Those were "bearer bonds" meaning
- the bearer (the person who had physical possession of the bond) owned
- it. Today, many bonds are issued as "registered" which means even if
- you get to touch the actual bond at all, it will be registered in your
- name and interest will be mailed to you every 6 months. It is not too
- common to see such coupons. Registered bonds will not generally have
- coupons, but may still pay interest each year. It's sort of like the
- issuer is clipping the coupons for you and mailing you a check. But
- if they pay interest periodically, they are still called Coupon Bonds,
- just as if the coupons were attached.
-
- When the bond matures, the issuer redeems the bond and pays you the
- face amount. You may have paid $1000 for the bond 20 years ago and
- you have received interest every 6 months for the last 20 years, and
- you now redeem the matured bond for $1000.
-
- A Zero-coupon bond has no coupons and there is no interest paid.
-
- But at maturity, the issuer promises to redeem the bond at face value.
- Obviously, the original cost of a $1000 bond is much less than $1000.
- The actual price depends on: a) the holding period -- the number of
- years to maturity, b) the prevailing interest rates, and c) the risk
- involved (with the bond issuer).
-
- Taxes: Even though the bond holder does not receive any interest while
- holding zeroes, in the US the IRS requires that you "impute" an annual
- interest income and report this income each year. Usually, the issuer
- will send you a Form 1099-OID (Original Issue Discount) which lists the
- imputed interest and which should be reported like any other interest
- you receive. There is also an IRS publication covering imputed interest
- on Original Issue Discount instruments.
-
- For capital gains purposes, the imputed interest you earned between the
- time you acquired and the time you sold or redeemed the bond is added to
- your cost basis. If you held the bond continually from the time it was
- issued until it matured, you will generally not have any gain or loss.
-
- Zeroes tend to be more susceptible to prevailing interest rates, and
- some people buy zeroes hoping to get capital gains when interest rates
- drop. There is high leverage. If rates go up, they can always hold them.
-
- Zeroes sometimes pay a better rate than coupon bonds (whether registered
- or not). When a zero is bought for a tax deferred account, such as an
- IRA, the imputed interest does not have to be reported as income, so
- the paperwork is lessened.
-
- Both corporate and municipalities issue zeroes, and imputed interest on
- municipals is tax-free in the same way coupon interest on municipals is.
- (The zero could be subject to AMT).
-
- Some marketeers have created their own zeroes, starting with coupon
- bonds, by clipping all the coupons and selling the bond less the coupons
- as one product -- very much like a zero -- and the coupons as another
- product. Even US Treasuries can be split into two products to form a
- zero US Treasury.
-
- There are other products which are combinations of zeroes and regular
- bonds. For example, a bond may be a zero for the first five years of
- its life, and pay a stated interest rate thereafter. It will be treated
- as an OID instrument while it pays no interest.
-
- (Note: The "no interest" must be part of the original offering; if a
- cumulative instrument intends to pay interest but defaults, that does not
- make this a zero and does not cause imputed interest to be calculated.)
-
- Like other bonds, some zeroes might be callable by the issuer (they are
- redeemed) prior to maturity, at a stated price.
