Warren Buffett's Berkshire Boosted by Bank of New York Mellon

Bank of New York Mellon has helped prop up Warren Buffett's Berkshire Hathaway portfolio, taking double digit gains this year along with a bunch of other financial services sector companies. When Capitol Hill calls to break up the banks, all Wall St. does is laugh or groan -- but when activist Nelson Peltz says he wants to break up BNY Mellon, it could be a sweet tune to the ears of Buffett and other investors. After all, the company's asset management business could be easily cleaved off for a buyer or as a standalone. As we close out Buffett's picks on Chart of the Day, it's a New York bank pick.
