Wednesday 3/14 Insider Buying Report: ETM, REVG (3/14, 10:44 AM ET) -- Bargain hunters are wise to pay careful attention to insider buying, because although there are many various reasons for an insider to sell a stock, presumably the only reason they would use their hard-earned cash to make a purchase, is that they expect to make money.
