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. However, some notable investors such as Warren Buffett have stated that there is no theoretical difference between the concepts of value and growth (“Growth and Value Investing are joined at the hip”), in consideration of the concept of an asset’s intrinsic value. Thomas Rowe Price, Jr. has been called “the father of growth investing”.
