Why Blue Apron Holdings Soared as Much as 38.1% This Week

Without any official news releases from the company, it is hard to say what drove up Blue Apron's stock price. Blue Apron didn't publish any official news or major filings with the Securities and Exchange Commission (SEC) this week, so investors were not reacting to any fundamental changes to the underlying business. Finance, approximately 23% of Blue Apron's float (shares that are publicly traded) were sold short as of the end of July.
