Fidelity Doubles Stake in Chrysler: Boston-based FMR Corp., parent of Fidelity Investments, the largest U.S. mutual fund company, notified the Securities and Exchange Commission that it owns 48.3 million shares of Chrysler Corp. stock, slightly more than 13% of the shares outstanding. FMR is the second-largest Chrysler shareholder to investor Kirk Kerkorian, who tried to take over the company this year and whose 50 million shares comprise about 13.1%. FMR’s stake has increased from 6.59% since the end of March. A spokeswoman said there would be no comment on it beyond the filing, which was a required quarterly update on the holdings of its mutual funds. Representatives of Chrysler and Tracinda Corp., Kerkorian’s company, also declined comment.
