摘要

In 1999 it was dot-com new issues. In 1957 uranium mining stocks were hot. In 1637 investors were overweight tulip bulbs. An ever present hazard on Wall Street is the risk of falling prey to an investing fad. I see one building right now. I can see it by looking at the press releases that float in over the transom. The frenzy of the moment is "smart beta." A beta coefficient, by itself, is a legitimate measure of the risk in a portfolio. If it's 1.5, then the portfolio is expected to lurch up 15% when the market goes up 10%, or down 15% if the market goes down 10%. A fundamental law of investing says that risk cuts both ways. Smart beta is a little less fundamental. It's the notion that you can beat the market by fiddling with the buttons on your stock screen. You could, for example, change the way you weight the positions in a portfolio. Instead of holding stakes proportional to each company's market capitalization, as stock indexes traditionally do, you could weight them equally or weight them according to book value, dividends or earnings.
