GameStop's stock jumps over 10% after Roaring Kitty tweet

Influential GameStop trader Keith Gill, who goes by Roaring Kitty on social media, dusted off his X account to post another cryptic meme.

The meme shows a Time Magazine cover with a blank computer on it. People on X have speculated that the volume bar on-screen and magazine title could indicate that it's "time for high volume." The time shown on the computer screen shows 1:09 (which is 69 seconds) and 4:20 — two favorite numbers for internet memers.

This is the first time Gill has posted on X since early September. Gill did not immediately respond to a request to clarify the meaning of the post.

Shares of GameStop rose over 10% in the hour following the post. Meanwhile, shares of fellow meme stock AMC Entertainment were also up over 10%.
