One way to make money from Friday's market bloodbath is by buying stocks with the "single-best estimate beats," Jim Cramer told viewers of his "Mad Money" TV show on Tuesday. Shaw Group ( SGR) fits this description. One of his favorite infrastructure plays, the company reported great numbers before last week's selloff and it's a stock people should think about buying, Cramer said. After its beat, the stock "powered up relentlessly" -- that's how good its quarter was -- but now because of the selloff, it's gone down and there is an entry point to get into this stock, Cramer said. Beyond its great quarter, another good reason to buy Shaw Group is that there is a scarcity of good nuclear plays, and it should benefit from a number of nuclear projects in the works, he said. "As each plant gets approval, the stock should go up."
