- This is the output of a program that I wrote to evaluate the average
- return of the DJIA as related to various calendar periods. It's based
- on the data from 1952-1980. It does not include dividends. It assumes
- that you bought the average at the closing price the day before the
- period began and sold at the closing price the day the period ended
- and paid no commisions. The performance figure is the amount that
- you would have if you started in 1952 with $1.00
-
-
- This series evaluates the average performance of holding the DJIA for
- the 1st, 2nd, ... nth calendar day of the month. Count is the number
- of such days found in the sample.

- The following two series evaluate 9 and 10 day cycles. They
- are intended to provide a check on the reliability of the other numbers.
- I don't know how to do statistical tests for significant differences
- between geometric means.
- What they seem to say is that you can ignore any numbers in the above
- that are within the range .8 to 1.5.

- carrot and stick. The numbers by themselves are not big enough
- to make money on if you are paying commissions, but what they
- say is that if you have decided to buy IBM for other reasons,
- Tuesday morning would probably be a good time. And Friday afternoon
- is a good time to sell.
