Elon Musk trolls short seller for betting against Tesla

Tesla CEO Elon Musk on Wednesday trolled short seller David Einhorn for betting against the automaker by saying, "Tragic. Will send Einhorn a box of short shorts to comfort him through this difficult time." Einhorn's hedge fund Greenlight Capital in its investor letter had said its bet against Tesla shares "was our second biggest loser" in the most recent quarter.
