Shares of major gunmakers rallied in premarket trading on Monday, one day after the deadliest mass shooting in US history.
Smith & Wesson shares jumped by as much as 9%, while Sturm, Ruger & Company shares rallied 4%.
At least 50 people died at a gay nightclub in Orlando on Sunday when Omar Mateen, the suspected gunman, opened fire with an assault-style rifle.
Gunmaker shares have rallied after previous mass shootings that revived the debate about tougher gun-control laws.
And amid prior calls from the White House to toughen gun laws, the companies have reported increased demand for their products; the concern among consumers is that guns may be harder to buy in the future if tougher 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 theatre, or a nightclub,” Obama said on Sunday.
