WASHINGTON – Shares of Chewy fell nearly 2 percent in overnight trading on Wednesday after a regulatory filing revealed that the meme stock trader known as Roaring Kitty sold its stake in the online pet retailer.

A beneficial ownership filing with the Securities and Exchange Commission released Tuesday showed that Roaring Kitty, whose legal name is Keith Gill, sold all of his shares in Chewy, which amounted to a 6.6 percent stake.

Plantation, Fla.-based Chewy fell 1.9 percent after hours to $26.19 a share.

Gill, an investor at the center of the meme stock craze, bought more than 9 million shares of Chewy in July, making him the company’s third-largest shareholder.

Gill made a name for himself in 2021 when he rounded up retail investors GameStop. At the time, the video game retailer was struggling to survive — and big Wall Street hedge funds and big investors were betting against it or shorting its stock. But Gill and those who agreed with him changed GameStop’s trajectory by buying thousands of shares in the face of nearly every accepted metric that told investors the company was in serious trouble.

That started what’s known as the “short squeeze,” when those big investors who had bet against GameStop were forced to buy its fast-rising stock to offset their massive losses.

Gill said he has confidence in GameStop President and CEO Ryan Cohen’s ability to modernize the company after what he did at Chewy. Cohen co-founded Chewy in 2011. He stepped down as CEO of Chewy in 2018.
