Biography
Keith Gill is an American individual investor who became prominent on Reddit's r/wallstreetbets under the handle DeepF***ingValue and on YouTube and X as Roaring Kitty. Beginning in 2019, he posted detailed bullish analyses and screenshots of his large GameStop position, arguing the stock was undervalued. His posts were widely cited as a driving factor in the GameStop short squeeze of January 2021, which caused dramatic price swings and significant losses for short-selling hedge funds. On February 18, 2021, he testified before the U.S. House Financial Services Committee, stating he did not solicit others to trade for his own profit. Regulatory scrutiny followed: his former employer MassMutual was fined for failing to supervise his online activity, though no finding of market manipulation against him resulted.
