Highfields acquires stake in Wendy's

It's the second time this week an investor has disclosed buying a large amount of Wendy's shares. Boston-based Highfields Capital Management LP said in a federal regulatory filing Thursday that it bought 6.9 million shares of the hamburger chain in March. On Tuesday, Pershing Square Capital Management LP in New York said in a Securities and Exchange Commission filing that it had acquired stock and options that could give it a 9.3 percent stake in Wendy's, and that it may seek major changes at the fast-food chain.
