Jack Dorsey resigned from his post as CEO of the social media company on Monday and will be replaced by chief technology officer Parag Agrawal. Mitch Rubin, portfolio manager at RiverPark Long/Short Opportunity Fund, joined Cheddar to break down the move and what it means for investors in both Twitter and Square, the payment company that Dorsey also helms. "For the long-term, I think this is very positive news for both companies," he said. Rubin also talked about growing competition in the social media space and why Twitter continues to lag behind other major players.
