Why Stock Pickers Keep Trying to Beat a Market They Know They Can't

Summarized from MarketWatch.com - Top Stories

Most active investors know the odds are stacked against them, yet they keep trading. Here's how to manage that impulse without wrecking your portfolio.

Millions of individual investors continue to pick stocks and attempt to outperform the broader market even as decades of evidence — and most financial professionals — confirm the effort is largely futile for the average person. The tension between what investors know intellectually and what they do emotionally sits at the heart of one of personal finance's most persistent puzzles.

Q.How much can underperforming the market actually cost an investor over time?

Even lagging the market by just one or two percentage points per year can result in a substantially smaller portfolio over a 20- to 30-year investment horizon due to the effects of compounding.
