Philip Arthur Fisher

Growth investing. Fisher, a California fund manager, took the opposite view to Graham: buy a few outstanding, growing companies and hold them for decades, even at prices that look high. His 1958 book Common Stocks and Uncommon Profits recommended scuttlebutt, interviewing customers, suppliers and competitors to judge management. He held Motorola for decades. The method needs rare judgement and patience, and is easy to confuse with simply paying too much.
