Growth investing means buying companies expected to grow earnings faster than the market. The goal is capital appreciation rather than income.

Bottom Line
Growth investing can generate exceptional returns but requires discipline. Focus on companies with sustainable competitive advantages, strong unit economics, and large addressable markets. Diversify across sectors, size positions based on conviction, and be willing to sell when the thesis breaks. The best growth investors buy great companies and let them compound for years.
