This option is used to maintain current and historical share prices
of securities in your portfolio data base. Additionally, you may
record market index data such as the Standard and Poor's 500 index
for graphic analysis using the charting capabilities of the program.
Current/historical price and index data are recorded on a weekly
basis and retained for the most recent 52 weeks. The Sunday business
section of most major newspapers lists all the information required
to maintain these records.
When you select the "UPDATE PRICES HISTORY" option from the main
menu, the "UPDATE PRICES FOR" menu appears listing the following
options:
╒═══════════════════════════╕

Table 5-1
These options allow the user the flexibility to perform weekly
updates on all stocks and indexes, selectively update individual
stocks and indexes, and backfill historical prices of individual
stocks and market indexes.
DATA REQUIRED
Depending on the option selected you should be prepared to enter the
data listed in Tables 5-2 and/or 5-3.
Page 14
When entering current and/or historical price data, the system checks
for previous entries for the date you are updating. If you have
previously entered data for that date the system warns you of this
fact and allows you the option of either overwriting the old data or
retaining it.

Table 5-3
ALL STOCKS/INDEXES 1 WEEK
In general you will choose this option to perform your weekly
updates. This option provides for automatic cycling through all
securities in your portfolio as well as all market indexes which you
are tracking.
Page 15
When you select this option you will enter the market date only once
and the system will provide data entry screens for all securities and
market indexes you are tracking. This allows you to update each
security and index without individually selecting them from a menu.
If you have not previously entered current and/or historical price
data for a security in your portfolio, the system asks if you wish to
track that security. If you wish to track the price of that security
then type Y. If not, type N and the system will proceed to the next
security in your portfolio.
ONE STOCK 1 WEEK
This option is used to update individual securities in your
portfolio. After selecting this option, you choose the security you
wish to update from a menu. As above, if you have not previously
entered data for this security, the system will ask if you wish to
track this security. Answer the question by typing Y or N and
proceed with data entry or your next "UPDATE PRICES FOR" menu
selection, respectively.
ONE STOCK MULTIPLE WEEKS
In general this option is used to backfill multiple weeks of
historical price and volume data for an individual security. After
selecting this option, you choose the security you wish to update
from a menu. You then enter the date for the first week of your data
and proceed with data entry. After entering and verifying the data
for one week, the system automatically increments the date for the
next week and requests that data. The sequence is ended by entering
a backslash (\) in the weekly high data field.
ONE INDEX 1 WEEK AND ONE INDEX MULTIPLE WEEKS
These options are functionally the same as their counterparts for
stocks except that you select from among market indexes which you
have previously defined.
DEFINE A NEW MARKET INDEX
This option is used to define the name of a market index which you
wish to track along with your securities. When you select this
option a data entry screen will be displayed requesting that you
enter a four character abbreviation for the market index and up to a
20 character name. Examples are listed in Table 5-4.

Table 5-4
DELETE AN INDEX
This option is used to delete a stock index record from your data
files when you are no longer interested in tracking that index.
When you select this option, a menu listing all the indexes in your
data files will be displayed. To delete an index record, select
the index you wish to delete, and confirm that your selection
is correct. If you accidentally select the wrong index, the deletion
process can be aborted by answering no to the question "Are you sure
you want to delete this index?"
X-DIVIDEND HISTORY UPDATE
This option allows you to update the price history of a given
security to compensate for payment of an X-Dividend. As
distinguished from ordinary dividends, payment of extraordinary (X)
dividends causes a devaluation of the market share price equal to the
amount of the dividend per share. If the price history is not
adjusted for payment of an X-Dividend, a discontinuity of share price
would appear at the record date of the X-Dividend when plotted over
time.
After selecting the "X-DIVIDEND PRICE UPDATE" option from the menu,
you will select the security for which the X-Dividend was paid, enter
the record date, and enter the amount of dividend per share.
Historical prices on or before the record date will be adjusted on a
percentage basis. You should be aware that this does not
automatically create a record of dividend income received. Use the
dividend income option from the main menu to record any dividend
income actually received by you.
