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 dollars to make a purchase, is that they expect to make money. Today we look at two noteworthy recent insider buys.

On Friday, Cullen/Frost Bankers's Director, Samuel G. Dawson, made a $99,857 purchase of CFR, buying 1,306 shares at a cost of $76.46 a piece. Cullen/Frost Bankers, Inc. is trading up about 0.1% on the day Monday.

And on Wednesday, James Murchie bought $71,522 worth of First Trust Energy Infrastructure Fund, buying 6,500 shares at a cost of $11.00 each. First Trust Energy Infrastructure Fund is trading up about 0.7% on the day Monday.
