GameStop Jumps 63% in After Market, to $243 and Counting By Investing.com

Investing.com — There’s speculation, and then there’s just plain crazy. GameStop Corp (NYSE:GME) shares soared 62% after the market closed on Tuesday, to reach $243, and that’s after nearly doubling during regular trading hours.

Elon Musk appears to have something to do with this.

The Tesla Inc (NASDAQ:TSLA) CEO, who is known for his itchy Twitter trigger finger, tweeted a shoutout late Tuesday and a link to the Reddit board whose members reportedly are responsible for the run-up in GameStop shares in recent days. The retail investors are battling professional traders who have heavily shorted the stock.
