How Do I Use This Information? There are many investment theories that are well publicized in the financial press. Even though little or no historical data may be offered as evidence for such theories, many investors use them subconsciously, if not intentionally.
Example Theories: Rising Inflation is bad for the stock market. A booming housing market is good for the S&P 500 stock index. A falling fed funds rate means that long term interest rates will fall.
There are many such theories. In this site, long term investment and economic data is tested against decades to determine whether a relationship actually exists or not. This historical correlation provides a vital aid in interpreting the often confusing behavior of the financial markets. The perspective gained may be the difference between staying the course or being blown and tossed by every investment theory that is popular at the moment. What the majority assumes to be true, often is not. In the final analysis, readers are admonished to follow the evidence, wherever it leads.

Formula for periods with a rising 30 Year Mortgage Rate: 1) Change in the Historical DJIA Return Rate DURING periods with a rising 30 Year Mortgage Rate: The abbreviated formula is: (Historical DJIA Return Rate Change / 30 Year Mortgage Rate Rise) x 1% = Published Rate.
The complete formula is: [(Average change in the Historical DJIA Return Rate over all rolling 12 month periods with a rising 30 Year Mortgage Rate) / (Average Rise in the 30 Year Mortgage Rate over the same 12 month periods)] x 1% = Published Rate.
2) Change in the Historical DJIA Return Rate AFTER a rising 30 Year Mortgage Rate: The abbreviated formula is: (Subsequent Historical DJIA Return Rate Change / 30 Year Mortgage Rate Rise) x 1% = Published Rate.
The complete formula is: [(Average change in the Historical DJIA Return Rate during the 12 months following any rolling 12 month base period with a rising 30 Year Mortgage Rate) / (Average Rise in the 30 Year Mortgage Rate over the 12 month base periods)] x 1% = Published Rate.
Formula for periods with a declining 30 Year Mortgage Rate: 1) Change in the Historical DJIA Return Rate DURING periods with a declining 30 Year Mortgage Rate: The abbreviated formula is: (Historical DJIA Return Rate Change / 30 Year Mortgage Rate Decline) x 1% = Published Rate.
The complete formula is: [(Average change in the Historical DJIA Return Rate over all rolling 12 month periods with a declining 30 Year Mortgage Rate) / (Average decline in the 30 Year Mortgage Rate over the same 12 month periods)] x 1% = Published Rate.
2) Change in the Historical DJIA Return Rate AFTER a decreasing 30 Year Mortgage Rate: The abbreviated formula is: (Subsequent Historical DJIA Return Rate Change / 30 Year Mortgage Rate Decrease) x 1% = Published Rate.
The complete formula is: [(Average change in the Historical DJIA Return Rate during the 12 months following any rolling 12 month base period with a declining 30 Year Mortgage Rate) / (Average decline in the 30 Year Mortgage Rate over the 12 month base periods)] x 1% = Published Rate.
Rolling 12 Month Periods Defined: Overlapping 12 month periods in a monthly data base.
For example: In the 24 month period included in 2000  2001, there are 13 complete rolling 12 month periods. The first is January, 2000  December, 2000. The second is February, 2000  January, 2001. The third is March, 2000  February, 2001 and so on. The last complete rolling 12 month period in the 2000  2001 period is January, 2001  December, 2001.
