Stocks for the Long Run – 4 Important Takeaways, Part 1

One of my favorite investment books is “Stocks for the Long Run” by Jeremy Siegel. The book uses historical data going back to 1802 to make a case for owning stocks, despite their risks. It was originally published in 1994 and he has since made several editions, usually a few years after a recession to reassure his readers that in fact his advice has not changed despite a changing investment environment.


I’ll admit the book can be a bit dense so I wanted to expand on 4 important takeaways from the book to save you some time.


Part 1 - Stocks have historically been less risky than bonds over long time horizons


I know that may be surprising to hear. Jeremy explains that for most investors, the best way to measure risk is to examine what the worst-case scenario could be. To do this he examines the best and worst after-inflation returns for stocks, bonds, and T-bills from 1802-2012.  Stocks were measured as dividends (plus capital gains) on a broad based capitalization-weighted index of U.S stocks.


Not surprisingly, stocks were considerably riskier over short time frames.



1 Year Worst Annualized Return

5 Year Worst Annualized Return

Stocks: -38.6%

Stocks: -11.9%

Bonds: -21.9%

Bonds: -10.1%

T-Bills: -15.6

T-Bills: -8.3


However, when the time horizons got longer, the worst case scenario for stocks not only was better than bonds or T-bills, it was actually much easier to predict what those returns might be. 


10 Year Worst Annualized Return

30 Year Worst Annualized Return

Stocks: -4.1%

Stocks: 2.6%

Bonds: -5.4%

Bonds: -2.0%

T-Bills: -5.1

T-Bills: -1.8%


During the 30 year time periods the best annualized return was 10.6% vs. 7.8% for bonds. So the range of returns for stocks was 8% while the range of returns for bonds was nearly 10%. According to Mr. Siegel’s data, stocks actually produced more predictive after-inflation returns over 30 year time horizons!
