Most of the book takes a long-term view of the financial markets, starting in 1802, mainly in USA (but with some comparisons with other markets). Siegel takes an empirical perspective to answer some major investing questions.
Even though the book has been termed "the buy and hold Bible" , the author occasionally concedes that there can be some market inefficiencies that can be exploited.
Siegel argues that stocks have returned an average of 6.5 percent to 7 percent per year after inflation over the last 200 years. He expects returns to be somewhat lower in the next couple of decades. In he states:
A significant part of the book is based on his academic and non-academic publications, many of which can be found on his web-site
The book covers the following topics.
The next edition includes a new chapter on globalization that argues that the emerging world will soon overtake the developed world. A discussion on fundamentally-weighted indexes which have historically resulted in better returns and lower volatility has been added.

This table presents some of the main findings presented in Chap 1 and some related text. Stocks on the long term have returned 6.8% per year after inflation, whereas gold has returned -0.4% (i.e. failed to keep up with inflation) and bonds have returned 1.7%. The equity risk premium (excess return of stocks over bonds) has ranged between 0 to 11%, it was 3% in 2001also. The Fed model of stock valuation was not applicable before 1966. Before 1982, the treasury yields were generally less than stock earnings yield.
Why the long-term return is relatively constant, remains a mystery.
The dividend yield is correlated with real GDP growth, as shown in Table 6.1.
Explanation of abnormal behavior:
In chapter 2, he argues (Figure 2.1) that given sufficiently long period of time, stocks are less risky than bonds, where risk is defined as the standard deviation of annual return. During 1802-2001, the worst 1-year returns for stocks and bonds were -38.6% and -21.9% respectively. However for a holding period of 10-years, the worst performance for stocks and bonds were -4.1% and -5.4%; and for a holding period of 20 years, stocks have never lost money. Figure 2.6 shows that the optimally lowest risk portfolio even for one-year holding, will include some stocks.
In Chapter 5, he shows that after-tax returns for bonds can be negative for significant period of time.
| Duration | Stocks | Stocks after tax | Bonds | Bonds after tax |
|---|---|---|---|---|
| 1871-2001 | 6.8 | 5.4 | 2.8 | 1.8 |
| 1946-1965 | 10.0 | 7.0 | -1.2 | -2.0 |
| 1966-1981 | -0.4 | -2.2 | -4.2 | -6.1 |
| 1982-2001 | 10.5 | 6.1 | 8.5 | 5.1 |
Some of the critics argue that the book uses a perspective that is too long term to be applicable to today's long-term investors.
