NEW YORK (Reuters) -The clock is ticking for Keith Gill, the stock influencer known on YouTube as "Roaring Kitty," to lock in gains on his options position in GameStop as the company’s share price swings wildly and the expiration date for the contracts draws closer. Gill helped launch the meme-stock phenomenon in 2021. The value of his sizeable GameStop options holdings briefly slipped into the red on Tuesday when the stock tumbled by as much as 8%.
