Keith Gill

Keith Patrick Gill (born June 8, 1986) is an American financial marketer and educator and individual investor known for his posts on the subreddits r/wallstreetbets and r/SuperStonk. His analyses of GameStop stock (NYSE: GME) and details of his resulting investment gains—posted on Reddit under the username DeepFuckingValue (DFV) and on YouTube and Twitter as Roaring Kitty, were cited as a driving factor in the GameStop short squeeze of January 2021, and as a spark for the subsequent trading frenzy in retail stocks. The rising stock value allowed Gill to turn an initial US$53,000 investment into $50 million by January 2021. Between 2021–2024, Gill kept a low profile but continued to increase his GameStop ownership. As of June 2024, Gill owned 9 million Class A shares of Chewy, Inc.

Gill's posts were described as "forthright, spreadsheet-laden content". His Reddit username derives from the investing term deep value, as Gill claims to be a proponent of value investing. Reuters revealed his identity to the public on January 28, 2021, after an investigation of public records and social-media posts.

Gill gave testimony as part of a virtual hearing held by the US House Financial Services Committee on February 18, 2021, as part of a discussion about when "short sellers, social media, and retail investors collide". Gill testified he "did not solicit anyone to buy or sell the stock for [his] own profit."
