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.
His son Kenneth L. Fisher also founded an investment firm. Perhaps the best-known of Fisher's followers is Warren Buffett who has said in some occasions that his investment view is a 15% Philip Fisher and 85% Benjamin Graham.
