Dividend reinvestment as the bear market protector and return accelerator.
Siegel argues that investors systematically overpay for growth and that the highest long-run returns have come from established companies in mature or declining industries that were priced low and paid dividends which were reinvested.
His central evidence is a study of the original 1957 Standard and Poor's 500 constituents held to 2003. He finds the best performer over that period was Philip Morris, a company in a shrinking, litigated, heavily taxed industry, and that the portfolio of original constituents held without change outperformed the continuously updated index. His explanation is what he calls the growth trap: investors bid up companies and sectors with visible growth prospects to prices that impound more growth than is delivered, while ignored companies with low expectations deliver returns above their price implies. Dividend reinvestment is the mechanism, since a low-priced stock's reinvested dividends buy more shares, which he calls the bear market protector and return accelerator.
He extends this to new issues, arguing that initial public offerings as a class have underperformed, and to sectors and countries, arguing that the fastest-growing economies have not produced the best equity returns.
The second half of the book concerns demographics, arguing that ageing populations in developed countries will need to sell assets to fund retirement and that buyers will come from developing economies. That argument is speculative and has not played out as described.
The study methodology has been criticised, particularly on survivorship and on the treatment of spin-offs and mergers among the original constituents. The growth trap finding is consistent with the broader value literature.
