Monday’s rally in gun stocks came hours after Hillary Clinton, the former secretary of state and the Democratic candidate for the president, unveiled a plan calling for tougher background checks at gun shows and online than those currently in place.

“We need universal background checks,” Clinton said at the New Hampshire town hall. “We know that they will work.”

Obama also renewed his calls for tougher gun control laws on Thursday, after a deadly shooting at Umpqua Community College in Oregon.
