What Warren Buffett’s Apple sale brings back to the investment world?

Warren Buffett’s longtime business partner Charlie Munger brought quality to value investing. Now Buffett is bringing value to quality investing.

At Berkshire Hathaway Inc.’s annual meeting in May, Buffett revealed that he had trimmed his stake in Apple Inc., inarguably one of the best businesses in the world. Buffett reassured the Berkshire faithful that he is no less enthusiastic about the company, calling the iPhone one of the greatest products of all time and Apple an even more wonderful business than American Express Co. and Coca Cola Co., two prominent investments in Berkshire’s portfolio.
