Buy-and-Hold Dollar Projections

I have constructed tables with the projected stock market returns in dollars for 1995-2005 at 10, 20 and 30 years to assist buy-and-hold investors.

Buy-and-Hold Projections

These projections are to assist in understanding. I have based these projections only on the valuations during 1995-2005. I have not made any adjustments for what has happened in the meantime.

Buy-and-Hold Equations

Here are the equations.

Here is the regression equation for the 10-year stock return and the percentage earnings yield 100E10/P (using 1923-1972 data): y = 1.5247x-4.5509 where y is the annualized real return in percent and x is 100E10/P or 100/[P/E10]. The confidence limits are plus and minus 6%.

Here is the regression equation for the 20-year stock return and the percentage earnings yield 100E10/P (using 1923-1972 data): y = 1.0849x-1.4488 where y is the annualized real return in percent and x is 100E10/P or 100/[P/E10]. The confidence limits are plus and minus 4%.

Here is the regression equation for the 30-year stock return and the percentage earnings yield 100E10/P (using 1923-1972 data): y = 0.4159x+3.764 where y is the annualized real return in percent and x is 100E10/P or 100/[P/E10]. The confidence limits are plus and minus 2%.

P/E10 Values for 1995-2005

Here are the January values of P/E10, rounded. I have taken them from Professor Robert Shiller’s S&P500 database.

10-Year Projections

Here are projections of the final balances after 10 years. The initial balances are all $10K.

The 5% and 95% confidence levels are –6% and +6% about the Calculated Rate, respectively. That is, 5% of all outcomes will be below the 5% confidence level. And 95% will be below (and 5% will be above) the 95% confidence level. The 20% and 80% confidence levels are –3% and +3% about the Calculated Rate, respectively. That is, 20% of all outcomes will be below the 20% confidence level. And 80% will be below (and 20% will be above) the 80% confidence level. One-half of all outcomes will be above the Calculated Rate. And one-half will be below the Calculated Rate.

To clarify: the 1995 10-Year Calculated Rate is 2.99%. The confidence levels are based on real, annualized returns of (3.01%), (0.01%), 2.99%, 5.99% and 8.99%.

What these Projections Tell Us

The years 1995-2005 have had the highest valuations in the historical record. P/E10 levels above 20 are unusual. The worst (January) levels before the bubble were 24 and 27, corresponding to the two worst times financially (1966 and 1929) to begin retirement.

The 10-Year projections show that whether investors would make money was close to a coin toss throughout the entire period. There was a high degree of uncertainty. Roughly, investors could expect returns ranging from one-half of the amount indicated by the equations (i.e., one-half of the Calculated Rate) to twice the indicated amount.

The 20-Year projections show that investors were likely to make money. There was still a high degree of uncertainty. Roughly, there was still about a 20% chance of loss. There was also a 20% chance of doubling one’s money.

The 30-Year projections show that investors were almost certain to do well. Even starting from the highest valuations, they were likely to multiply their initial investment by four times. The worst case was to double one’s money. The upside potential starting from the highest valuations was to multiply one’s money by seven.

Investors who started in 1995 and 2003 could expect a 30% higher 30-year final balance than those who started at the peak of the bubble. The 1995 and 2003 P/E10 levels were much more reasonable, but still very high at 20 and 23. The Calculated Rates for 1995 and 2003 were about 1% below the historical average. [When P/E10 = 15, the 30-Year Calculated Rate is 6.54%. The 1995 30-Year Calculated Rate was 5.82%. The 2003 30-Year Calculated Rate was 5.58%.]

Have fun.
