Shares in Etsy and GameStop surged this week after Tesla boss Elon Musk tweeted about the companies. Musk's GameStop tweet added to an ongoing siege against Wall Streetfrom by a community on Reddit that appeared to be costing corporate hedge funds both power and profit.

Trading was volatile this week as investors from the Reddit community r/wallstreetbets poured funds into video game retailer GameStop (GME), sending shares soaring by over 400 percent in seven days—and resulting in disruption of short sellers.
