Philip Arthur Fisher (September 8, 1907 – March 11, 2004) was a stock investor best known as the author of Common Stocks and Uncommon Profits, a guide to investing that has remained in print ever since it was first published in 1958. His money management company, Fisher & Co., was founded in 1931.
Philip Fisher is considered a pioneer in the field of growth investing. Morningstar has called him "one of the great investors of all time." In Common Stocks and Uncommon Profits, Fisher said that the best time to sell a stock was "almost never". His most famous investment was his purchase of Motorola, a company he bought in 1955 when it was a radio manufacturer and held until his death.
