eBay (EBAY) gained 1.2% partly as the CEO said the company is looking at non-fungible tokens or NFTs."We're looking at it and exploring opportunities as for how we can enable it on eBay in an easy way," CEO Jamie Iannone said in an interview on CNBC.NFTs have gained in popularity this year and are largely responsible for moves in stocks such as PLBY Group, the parent of Playboy, which has surged 367% this year and SPAC Mudrick Acquisition Corp. II, which has climbed 63%, on a deal to take Topps trading cards public. Last week, eBay slides after guidance disappoints, downgrades pile up.
