Watch CNBC's full interview with Wharton's David Erickson on Robinhood

David Erickson, Wharton senior fellow and former co-head of global equity capital markets at Barclays, joins CNBC's 'Squawk Box' to discuss shares of Robinhood, which have plummeted following the company's quarterly earnings report last week. Erickson explains why Robinhood could benefit from new leadership or a potential merger with fintech company SoFi. "They missed their first quarter out of the box, which is really a big sin when you're a newly public company," Erickson tells CNBC.
