Reddit trading star known as “Roaring Kitty” defended his social media posts that helped spark a mania in GameStop shares last month in testimony released on Wednesday, saying he was an individual investor acting only on publicly-available information. The trader, whose real name is Keith Gill, is set to testify to the U.S. House of Representatives’ Committee on Financial Services on Thursday. Other than defending his actions, Gill used his testimony to again make the case for why he is still bullish on GameStop.
