Cash pile

Berkshire Hathaway, the investment conglomerate led by legendary value investor Warren Buffett, currently holds an astonishing $334 billion in cash and Treasury bills. This war chest is now large enough to acquire 476 of the 500 companies in the S&P 500 outright. It's no surprise, then, that Berkshire's stock is up 14% year-to-date, while the broader S&P 500 has declined by 10%.
