Shares of Square (NYSE: SQ) have declined nearly 30% since the beginning of the year, and currently hover just above its IPO price of $9. The online payments processor has been battered by lackluster sales growth, non-existent profitability, and a lockup expiration in mid-May. CEO Jack Dorsey’s ability to simultaneously lead Square and Twitter has also been repeatedly questioned. Should investors consider Square a contrarian buy, or could it fall far below its IPO price like Twitter?
