When a stock price plummets, mostinvestors jump ship. But if the fundamentalsbehind the stock remain positive, thechances are good that it will recover.That's when savvy stock pickers likeWilliam Miller, who heads up LeggMason's Value Trust fund (800-822-5544), start to buy in, often buying all theway down to the bottom. This kind ofdollar-cost averaging has led Miller's fundto an eye-popping 12-year winning streakover the S&P 500. Miller notes that individualinvestors can put a less risky versionof this strategy into practice withmutual funds. Instead of buying fundsthat are going up and selling those goingdown, as typical investors do, Miller says,try doing the opposite.
