Bed Bath & Beyond Inc (NASDAQ:BBBY) shares are tanking in Thursday's after-hours session after a new SEC filing confirmed that GameStop Corp (NYSE:GME) chair Ryan Cohen sold his stake in the home furnishings retailer.

According to a Form 144 filing from earlier in the week, Cohen owned 7.78 million common shares, as well as 1,257 $60 strike call options, 444 $75 strike calls and 5,000 calls at the $80 strike. 

Although the Form 144 showing intent to sell had a notice date of Aug. 16, it was unclear if any shares had been sold. Thursday's 13D confirms that Cohen has exited his position completely.

According to a separate SEC filing, Bed Bath & Beyond CFO Gustavo Arnal sold 55,013 shares of the company this week. However, the reported transactions were effected pursuant to a Rule 10b5-1 plan, which Arnal entered into in April.
