GameStop (GME) stock rose more than 30% on Thursday after a YouTube account believed to be tied to investor Keith Gill, also known as “Roaring Kitty” on social media, posted a livestream scheduled for Friday at noon ET.

This would be the first live appearance on the channel since Gill helped ignite the meme stock rally in 2021 via bullish videos and posts about the video game retailer.

“The Roaring Kitty channel and live streams are for educational and entertainment purposes only. I don’t provide personal investment advice or stock recommendations during the stream,” read the YouTube account’s description.

The channel has about 706,000 subscribers.

Shares of GameStop have been on a rollercoaster over the past month as Gill, also known as DeepF—ing Value on Reddit, reemerged across social media.

On Monday, shares surged 21% after an account also believed to be tied to Gill posted a screenshot on Reddit that purported to show a holding of nearly $175 million in GameStop stock and call options.

The following session the stock declined 5%. The Wall Street Journal reported that executives at JPMorgan’s (JPM) E*Trade platform were considering kicking off the account tied to the screenshot.

“Is whoever controlling this account doing this in your best interest or in their best interest? And, really, you should think that one through because, to me, it [is] pretty obvious whose interest it’s in,” Sosnick said.

“If you’re chasing the stock up here, you’re more likely than not the source of liquidity for whoever is controlling this account to sell into your enthusiasm.”

GameStop also rallied 180% over a span of two days in mid-May after “Roaring Kitty” posted for the first time on X, formerly known as Twitter, since 2021.

Last month’s rally was short-lived, and analysts warned the meme action this time around was a far cry from the level of retail inflows seen in 2021.

Shares of fellow meme stock AMC (AMC) have been riding GameStop’s coattails. The stock rose 10% on Monday.
