"Gun stocks are surging, even as America mourns another mass shooting and Hillary Clinton vows to restrict sales. Popular gun companies Smith & Wesson (SWHC) and Sturm Ruger (RGR) are among the best stocks in America in 2015. It's a reminder of just how profitable these businesses are. Smith & Wesson has skyrocketed over 80% this year. To put that in perspective, if the stock were in the S&P 500, it would be the second best performer this year, behind only Netflix (NFLX).... This stellar performance comes in a year when many stocks have tanked.... The reason investors like gun stocks is simple: people are buying a lot of guns. Sales hit a record for Smith & Wesson in 2014 and for Sturm Ruger in 2013."
