NEW YORK (Reuters) - Keith Gill, the stock influencer known as Roaring Kitty, updated his holding of GameStop on Thursday to show he now owns 9 million shares of the company, up from 5 million at the start of the week.

Gill's update, posted on Reddit after the close of trading, showed the value of his position at $262.1 million. That is 2.1% of GameStop's 426 million outstanding shares, according to a recent regulatory filing.

The update also showed he no longer holds the 120,000 June 21, $20 strike call options he had disclosed in his last update.
