5% to 6% for example) has typically been accompanied by a 1.69% DJIA Return Rate
decline during that year and a 0.81% DJIA Return Rate increase the following year.
It also indicates that a 1% Personal Savings Rate decline over a 12 month period,
(from 5% to 4% for example) has typically been accompanied by a 1.93% DJIA Return
Rate increase during that year and a 0.87% DJIA Return Rate decline the following
year.
The center column shows the change in the DJIA Return Rate over 12 months,
depending on whether the period experienced a rising or falling Personal Savings
Rate. The right column shows the change in the DJIA Return Rate during the year
following an increase or decrease in the Personal Savings Rate.
The data history in the middle column shows a strong tendency for the two
rates to move inversely to each other during the same time period.
The evidence for using the previous 12 month change in the Personal
Savings Rate to predict the future direction of the DJIA Return Rate is strong
(right column).
Annual rates are shown in the graph and calculations.
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.
This page tests the relationship between the Personal Savings Rate and the DJIA
Return Rate. Suppose you are making a business or investment decision. Suppose
again that the decision hinges on whether the Personal Savings Rate and the DJIA
Return Rate tend to move in the same or opposite directions. The DJIA History chart,
data, and analysis above will enlighten you. You'll discover whether they move with,
inversely to, or independently of each other.
Suppose that the Personal Savings Rate has risen sharply and that you need to know
what direction the DJIA Return Rate is headed in the near future. Does the recent
increase in the Personal Savings Rate provide a clue about the future direction of the
DJIA Return Rate? The DJIA history graph, and analysis above will show you how the
DJIA Return Rate has performed after increases in the Personal Savings Rate. You'll
see if one indicator has been likely to signal a change in another. This is not intended
as a prediction, but merely as a clue to the future from the annals of history. No man
knows the future, unless he has the ability to control the future.

Formula for periods with a rising Personal Savings Rate:
1) Change in the DJIA Return Rate DURING periods with a rising Personal Savings
Rate:
The abbreviated formula is: (DJIA Return Rate Change / Personal Savings Rate Rise)
x 1% = Published Rate.
The complete formula is: [(Average change in the DJIA Return Rate over all rolling 12
month periods with a rising Personal Savings Rate) / (Average Rise in the Personal
Savings Rate over the same 12 month periods)] x 1% = Published Rate.
2) Change in the DJIA Return Rate AFTER a rising Personal Savings Rate:
The abbreviated formula is: (Subsequent DJIA Return Rate Change / Personal
Savings Rate Rise) x 1% = Published Rate.
The complete formula is: [(Average change in the DJIA Return Rate during the 12
months following any rolling 12 month base period with a rising Personal Savings
Rate) / (Average Rise in the Personal Savings Rate over the 12 month base periods)]
x 1% = Published Rate.
Formula for periods with a declining Personal Savings Rate:
1) Change in the DJIA Return Rate DURING periods with a declining Personal Savings
Rate:
The abbreviated formula is: (DJIA Return Rate Change / Personal Savings Rate
Decline) x -1% = Published Rate.
The complete formula is: [(Average change in the DJIA Return Rate over all rolling 12
month periods with a declining Personal Savings Rate) / (Average decline in the
Personal Savings Rate over the same 12 month periods)] x -1% = Published Rate.
2) Change in the DJIA Return Rate AFTER a decreasing Personal Savings Rate:
The abbreviated formula is: (Subsequent DJIA Return Rate Change / Personal
Savings Rate Decrease) x -1% = Published Rate.
The complete formula is: [(Average change in the DJIA Return Rate during the 12
months following any rolling 12 month base period with a declining Personal Savings
Rate) / (Average decline in the Personal Savings 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.
