General Motors Co. fell to the lowest price in more than nine months after Morgan Stanley downgraded the Detroit-based company’s stock, saying investors’ profit-margin expectations are too high. Shares in the biggest U.S. automaker dropped 2.6 percent to $33.62 at the close in New York, after analyst Adam Jonas downgraded them to underweight. That was the lowest level since June 28. The loss for the year is 18 percent as GM and its Chief Executive Officer Mary Barra deal with criticism after delaying recalling 2.59 million cars linked to 13 deaths. http://www.bloomberg.com/news/2014-04-09/gm-slips-as-morgan-stanley-downgrades-stock-on-margin-concern.html
