David Einhorn of Greenlight Capital Inc. is no stranger to controversy. His current project is General Motors Corp. He put a flashlight on its common shares on March 28 arguing that they are unreasonably cheap. Immediately before the proposal was made GM’s shares were trading just below $35 per share, which equates to 5.8x 2016 earnings of $6.00 per share and 5.6x the midpoint of management’s 2017 guidance ($6.25 per share). The dividend yield is high at 4.4%, more than double the yield of the S&P 500. As Einhorn points out, the yield is not high because the payout ratio is high; the $1.52 per share dividend equates to just one quarter of (current) earnings.
