NEW YORK ( TheStreet) -- Think the horrific shootings in Aurora, Colo., and subsequent discussion of tougher gun laws might worry shareholders of publicly traded gun manufacturers? Think again. Shares of both Smith & Wesson Holding Corp. ( SWHC) and Sturm, Ruger & Co. ( RGR) have outperformed the broader market during the past two trading days since James Holmes allegedly walked into a crowded movie theater during a midnight premiere of The Dark Knight Rises and opened fire, killing 12 people and wounding 58 others. As of Monday's market close, shares of Smith & Wesson were down by less than .01% since the close of trading Thursday, before the shooting took place. Smith & Wesson manufactured one of the weapons allegedly used by Holmes in the shooting, according to news reports. Shares of Sturm, Ruger are up 3.6% over the same time period, while the Standard & Poor's 500 has fallen by 1.9% and the Dow Jones Industrial Average (DJIA) has fallen by 1.7%. Smith & Wesson and Sturm, Ruger are the only two publicly-traded gun manufacturers, though their revenues comprise just 25% of total US commercial gun sales, as most firearms manufacturers are privately held, according to a report published Monday by The Benchmark Company. The report, which previews Sturm, Ruger's scheduled release of second quarter earnings on Aug. 1, does not mention the Aurora shootings, but is bullish on prospects for both Sturm, Ruger and Smith & Wesson. It notes Sturm, Ruger has a "record backlog", but that "success for Smith & Wesson does not necessarily spell failure for Sturm, Ruger ." The report goes on to argue that "increased social acceptance will continue to drive new first-time firearm purchasers, and, depending on the outcome of the election in November, we could see continued political buying well into fiscal year 2013 ." The author of the report, analyst Mike Greene, did not clarify what he meant by "political buying," nor did he respond to a request for comment. However, some investors have lately been arguing that the strength in these gun stocks has paradoxically increased as a result of renewed debate over whether the U.S. should strengthen its gun laws. Writing on Twitter under the handle @event_trader on Monday, one market watcher wrote, "not surprising to see $RGR and $SWHC green today - renewed gun control debates generally spark fear sales ahead of any potential ban."
