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.

At Generation Bio, a filing with the SEC revealed that on Tuesday, Director Charles A.

Rowland Jr. bought 30,000 shares of GBIO, at a cost of $19.00 each, for a total investment of $570,000.

So far Rowland Jr. is in the green, up about 15.5% on their purchase based on today's trading high of $21.94.

And also on Tuesday, Director William K.

Hood bought $444,000 worth of First Guaranty Bancshares, buying 37,000 shares at a cost of $12.00 each.
