Keith Gill wrapped up his first YouTube livestream since the 2021 meme-stock mania. The meme lord addressed more than 650,000 people at one point, with scores of investors and market watchers tuning in to see what Gill has been up to since he first started streaming from the basement of his home in suburban Massachusetts. The livestream coincided with extreme volatility in GameStop shares, which were recently down more than 35% and were halted at least 16 times in recent trading.
