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. Today we look at one noteworthy recent insider buy.

At Hornbeck Offshore Services (HOS), a filing with the SEC revealed that on Monday, CFO James O. Harp Jr. bought 10,000 shares of HOS, at a cost of $19.86 each, for a total investment of $198,601. Harp Jr. was up about 6.7% on the buy at the high point of today's trading session, with HOS trading as high as $21.20 in trading on Wednesday. Hornbeck Offshore Services is trading off about 3.1% on the day Wednesday.
