This is part 3 in my series discussing “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.


Part 3 – There is a place for bonds in investment portfolios


The strong case for stocks over bonds that Siegel makes, he does address the purpose of bonds in the average retiree’s portfolio. While stocks have historically produced superior returns over longer time horizons – try telling a retiree to wait 20 years for things to correct.


The reality is that a portion of investments will likely be used to provide retirement income in the next 1, 5, or 10 years. This should be taken into consideration because there have been numerous short-term periods where stock returns have substantially underperformed bonds or cash.


Over shorter periods of time, the main objective of the investor is often predictability. Siegel analyzes this by calculating the standard deviation – which essentially estimates how predictable to returns could be. Using data from 1802-2012, he uses two asset classes, stocks and bonds. If you were trying to keep your deviation down as much as possible using just these two assets, he calculates that the following would be the best way to achieve it.



For money needed in 1 year: An allocation of 87% bonds and 13% stock 


For money needed in 5 years: An allocation of 75% bonds, 25% stock


For money needed in 10 years: An allocation 61% bonds, 39% stock
