Gunmaker shares have rallied after previous mass shootings that revived the debate about tougher gun-control laws.

President Barack Obama and Hillary Clinton, the presumptive Democratic presidential nominee, both called for stricter gun-control measures in statements on Sunday.

And amid prior calls from the White House to toughen laws, gunmakers have reported increased demand for their products; the concern among consumers is that guns may be harder to buy in the future if stricter legislation is passed.

The Orlando shooting was "a further reminder of how easy it is for someone to get their hands on a weapon that lets them shoot people in a school, or a house of worship, or a movie theater, or a nightclub," Obama said on Sunday.
