Krispy Kreme (DNUT), Opendoor (OPEN), Rocket Mortgage (RKT) and Kohl’s (KSS) had become the meme stocks of the moment, along with a new moniker from traders — “DORK,” a reference to the first letters of their tickers.

Kohl's and Krispy Kreme have been subject of online chatter, including on WallStreetBets, about their potential. Rocket Companies is up 6%.
