09:46 AM EDT, 05/13/2024 (MT Newswires) -- (Updates to add recent stock move in the headline and first paragraph.)

GameStop ( GME ) shares were up more than 68% in recent Monday trading after "Roaring Kitty," the social media persona that sparked a massive stock rally with the videogame retailer in 2021, returned online for the first time in three years.

Keith Gill, known as "Roaring Kitty" on YouTube and "DeepF------Value" on Reddit, posted on Monday a sketch of a video gamer leaning forward on their chair, a popular meme used to indicate that things are getting serious.

Gill's posts on Reddit's Wallstreetbets discussion group in 2021 about his gains investing in GameStop ( GME ) had inspired a stock rally on highly shorted stocks including GameStop ( GME ) and AMC.
