Square stock falls after Citron makes short call, says company is a 'collection of yawn businesses'

Shares of Square Inc. are down 3% in Monday trading after noted short-seller Citron Research made a short call on the stock. Shares were up 2.8% at their highest point Monday prior to the call. In a tweet, Citron announced a "short-term" target of $30, 35% below current levels, and said that the company's revenue is growing slower than that of Facebook Inc. The tweet also called Square "a collection of yawn businesses" and argued that traders are "drunk on Bitcoin nonsense," a reference to Square's allowance of Bitcoin trading through its peer-to-peer Square Cash app. Square's management has said that Bitcoin trading has a negligible impact on revenue. Shares are up 153% over the past 12 months, while the S&P 500 has gained 11%.
