GameStop soars 70% after flag bearer 'Roaring Kitty' resurfaces with X post

The Grapevine, Texas-based firm's rally also boosted other meme stocks that have been hammered over the past year. Theater chain jumped 27%, while headphones maker Koss Corp soared 23%.

Keith Gill, known as "" on YouTube and "DeepF***ingValue" on Reddit, was a key figure in the so-called , which saw shares of surge as much as 21-fold over two weeks in January 2021 before crashing to pre-surge levels in the subsequent days.

Gill on Sunday posted a sketch of a man leaning forward in a chair, a popular meme among gamers that indicates things are getting serious, with no caption.

The cryptic post is his first on X, earlier Twitter, after being notably absent on social media platforms since mid-2021.

"Roaring Kitty" did not immediately respond to a Reuters request for a comment.

GameStop and AMC were the most traded stocks among retail at 11 a.m. ET, J.P.Morgan data showed.

Roaring Kitty "seems to be the most likely suspect for the renewed interest today... but I would be careful not to characterize the participants in this phenomenon as investors," said Art Hogan, chief market strategist at B Riley Wealth.

"There's no fundamental change in any of the companies that are popularized in this phenomenon."

GameStop in March cut an unspecified number of jobs to reduce costs and reported lower fourth-quarter revenue.

Shares of the struggling videogame retailer have surged over 57% in May up to Friday's close, but still remain sharply below their $120 peak of 2021.

"It's unlikely you're going to see a repeat of meme stock mania for any sustained period of time because it was a point in time when you had a bunch of people stuck at home with free money and that's no longer the case," said Thomas Hayes, chairman at Great Hill Capital LLC.

The meme stock rally in 2021 was set off by Gill's posts on Reddit's discussion group about the gains he had made on his investments in the highly shorted firm.

The rally spread to other highly including AMC as Reddit users banded together to squeeze bearish hedge funds, costing them billions in losses and drawing scrutiny from U.S. regulators.

The entire episode inspired Craig Gillespie's 2023 movie "Dumb Money".
