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 two noteworthy recent insider buys.

On Thursday, RF Industries's CEO, Robert D. Dawson, made a $34,998 purchase of RFIL, buying 5,000 shares at a cost of $7.00 a piece. So far Dawson is in the green, up about 9.5% on their buy based on today's trading high of $7.67. RF Industries Ltd. is trading up about 1.3% on the day Friday. Before this latest buy, Dawson bought RFIL at 2 other times during the past twelve months, for a total cost of $23,750 at an average of $2.38 per share.

And on Wednesday, Director Roger Nicholas Sexauer II purchased $27,010 worth of Espey Manufacturing & Electronics, purchasing 1,000 shares at a cost of $27.01 a piece. Espey Manufacturing & Electronics Corp. is trading up about 0.3% on the day Friday. Bargain hunters have the opportunity to pick up ESP even cheaper than Sexauer II did, with the stock trading as low as $25.79 at last check today which is 4.5% below Sexauer II's purchase price.
