Despite a sell-off in Tesla Inc.’s (NASDAQ: TSLA) stock due to the erratic behavior of CEO Elon Musk, SEC scrutiny of his public statements, rumored turmoil among board members and risks that it can’t hit production targets, the electric car company’s market value is still higher than that of General Motors Co. (NYSE: GM). GM sells about 10 million cars a year. Tesla delivered slightly more than 40,000 last quarter.
