Billionaire Warren Buffett, marking 60 years leading Berkshire Hathaway, told shareholders in his annual letter released Saturday that he continues to prefer stocks despite a higher cash position.

Warren Buffett is celebrating the successes of Berkshire Hathaway’s companies last year and in the 60 years since he took over a struggling New England textile company and began converting it into a massive conglomerate.

The legendary investor wrote in Saturday’s annual letter that Berkshire Hathaway will never prefer cash over ‘good businesses.’
