Had you invested in an S&P 500 index fund in August 1997 and sat tight for 10 years, you'd have racked up an 88% return. Had you missed just the 20 best days in the market over that period, you would have had a 20%
loss, according to Chicago's Altair Advisers. Moral: Stock returns come in bursts. Step out of the market, even temporarily, and you may miss the whole point of owning stocks.
