Dick's Sporting Goods (DKS - Get Report) , which in early 2018 mulled whether to stop gun sales after a Florida mass shooting, reportedly is now again considering that move.

CNN reported, without saying where it got the information, that the company could announce that decision as soon as Thursday when it reports its quarterly results.

Dick's has been the most publicly prominent among the retailers about the subject of firearms sales, CNN reported.

After the Parkland shooting in February 2018, the Coraopolis, Pa., company stopped selling assault-style rifles and high-capacity magazines; raised the age at which customers could buy firearms to 21 from 18; destroyed its inventory of assault weapons; hired lobbyists on gun safety and gun control; and reduced the number of stores that carry hunting equipment, CNN reported.

After Parkland, Walmart (WMT - Get Report) raised the minimum age at which customers could buy firearms and ammunition to 21 from 18 and removed toys resembling assault-style weapons from inventory, the Washington Post reported.

The world's No. 1 retailer has been the target of a number of shooting attacks, including two recent ones in El Paso, Texas, and Southaven, Mississippi.

And it has come under pressure to remove guns from its stores. CEO Doug McMillon said in a statement Aug. 15, that the Bentonville, Ark., company supported strengthening some gun measures in the U.S., though he wasn't specific.

President Donald Trump apparently has been of two minds on the subject.

After the early-August mass shootings in Texas and Ohio, the president said he was prepared to endorse "very meaningful background checks" on people who wanted to buy firearms.

But recent reports say he has backed off that prospect after discussing the issue with gun-rights advocates, including the CEO of the National Rifle Association, Wayne LaPierre.

Dick's shares on Tuesday traded down 1.9% at $32.37, while Walmart fell 1.6% to $112.05.

The firearms companies traded mixed. American Outdoor Brands (AOBC - Get Report) , parent of Smith & Wesson, was off 2.4% at $7.61. Sturm Ruger (RGR - Get Report)  fell 2.7% to $40.70. Ammunition producer Vista Outdoor (VSTO - Get Report)  added 4.1% to $4.91.
