I updated my two favorite graphs this week. The first shows the cumulative real return for stocks and bonds for the last 100 years. Stocks outperformed bonds by a factor of 100. The second shows the results of head-to-head competitions for stocks and bonds for 25-year holding periods. Stocks are risk free because they’ve never lost money; stocks ~always have outperformed bonds.
== Fuel for growth ==
The point of this graph: jet fuel (stocks) outperformed candlewax (bonds) by a factor of 100.

Jet fuel: My straight line for stocks indicates they have averaged ~7.1% real return per year; if I drew the line to the exact end point, it would be 7.3% real return per year.
Using the Rule of 72, stocks double in real spending power ~every ten years; 100 years is ten doublings; $1 invested in stocks is now +$1,000.
Candlewax: Bonds have averaged ~2.3% real return per year; bonds double in real spending power ~30 years; 100 years is three doublings and 1/3 of the way to the next doubling. $1 invested in bonds in January 1926 is now <$10 in the same spending power.
I enclose a .pdf of the graph here.
== Stocks crush bonds for 25 years ==
The point of this graph: younger folks should be invested in STOCKS ONLY for many years. NO BONDS. Younger folks with an employer retirement plan contribute every month and their employer contributes for them. They can’t even touch this money without severe penalty to age 59½. They clearly have 25-year holding periods for those monthly investments.

Stocks have NO RISK of loss for 25-year holding periods. Their worst return was a 67% gain. Bonds are risky; they lost money in 22% of the sequences averaging 16% loss in those sequences.
Stocks are essentially RISK-FREE relative to bonds: stocks win the competition in 1552 of 1560 25-year sequences since 1871. (And they are on track to win the upcoming 300 next complete sequences). The last time bonds beat stocks was an investment in March 1984.
My graphs for shorter holding periods (not shown) aren’t quite as dramatic, but it’s still obvious that those in the save and invest phase of life must invest ONLY IN STOCKS for many years before they hit retirement age.

Conclusion: I updated my two favorite graphs. One shows the long, long-term trend for stocks is ~7.1% real return per year. Stocks double in real spending power ~every ten years. The trend line for bonds is ~2.3% real return per year; bonds double in real spending power ~every 30 years. Over the last 100 years, stocks have outperformed bond by a factor of 100.
The second graph plots the multiple of real return from an investment in stocks and bonds for 25-year holding periods. That’s 1,560 complete 25-year periods since January 1871. Stocks are risk-free because they’ve never returned less than 0%; bonds are not risk-free because they’ve lost money 22% of the time. Stocks are essentially risk-free relative to bonds because they have outperformed bonds in 99.5% of the sequences of return since January 1871.
Invest in STOCKS ONLY if you are in the Save and Invest phase of life.
