“Shares in two U.S. firearms companies were up Monday,” The Wall Street Journal reports, “after the U.S. Supreme Court stuck down the City of Chicago’s decades-old ban on individual ownership of handguns . . . The 5-4 ruling follows by about two years a similar ruling throwing out a handgun ban in the District of Columbia. Shares of Smith & Wesson Holdings (SWHC) rose 5.4% to $4.32 while Sturm, Ruger & Co. (RGR) rose 2.7% to $15.46.”
