Whitney Tilson highlighted a thesis by his colleague Enrique Abeyta that argues shares of Uber Technologies (UBER) are going to zero. Shares of Uber are up $1.09 to $31.20 in midday trading. “I wouldn’t be surprised if we look back in 18 months and Uber has filed for bankruptcy. In fact, that would be a logical expectation,” writes Abeyta, who recommends shorting both Uber and Lyft (LYFT).
