Growth investing is a style of investment strategy focused on capital appreciation. Those who follow this style, known as growth investors, invest in companies that exhibit signs of above-average growth, even if the share price appears expensive in terms of metrics such as price-to-earnings or price-to-book ratios. In typical usage, the term "growth investing" contrasts with the strategy known as value investing. Also influential in shaping this investment style was Phil Fisher, whose 1958 book "Common Stocks and Uncommon Profits" is still today a reference for identifying growth companies.
