Growth investing

Growth investing is a strategy centered on buying companies expected to grow their earnings significantly faster than the overall market or the economy, betting that expanding profits will eventually drive capital gains regardless of the starting valuation.

The growth thesis

A growth investor believes that the market underweights future earnings potential. A company may look expensive by current price-to-earnings ratio standards, but if its profits are doubling every two to three years, a $100 stock growing 30% per year will justify $200, then $260, then $338 over five years — regardless of whether the multiple itself expands.

This is fundamentally different from value investing. A value investor buys cheapness; a growth investor buys momentum in earnings. The starting valuation is not the enemy — rapid earnings growth is the tailwind.

What growth investors hunt for

• Double-digit earnings growth. Sustained profit expansion at 15%, 20%, 30% per year. The growth rate is often more important than the starting multiple.
• Market share gains. A company stealing customers from competitors and expanding its total addressable market (TAM).
• Pricing power. The ability to raise prices without losing customers, indicating a defensible competitive advantage.
• Reinvestment opportunity. The company has so many attractive uses for its capital that it can grow rapidly and reinvest heavily, reducing near-term dividends but expanding long-term value.
• Secular tailwinds. Growth trends (aging populations, cloud adoption, electrification, automation) that will compound the company’s natural growth.

Why growth stocks trade at a premium

A growth stock’s high price-to-earnings ratio is not irrational. If you believe Company A will grow earnings 20% per year and Company B 3%, paying 40x for A and 12x for B may be perfectly reasonable. The multiple reflects the growth rate.

However, this creates vulnerability: if growth slows unexpectedly, the multiple can compress rapidly, creating a double hit — lower earnings and a lower multiple on those earnings. This is why growth stocks are often volatile, especially in sectors like technology.

Growth versus value — the long debate

Over decades, value stocks have outperformed growth on average, but this is not a law of nature. In certain eras — the 1980s, the 1990s, and 2010–2021 — growth has dominated. Growth stocks also exhibit lower volatility than their valuation multiples might suggest when the underlying growth is durable.

The deepest insight is that the distinction is temporal: today’s growth stock becomes tomorrow’s value stock. A company with 30% growth becomes a company with 10% growth, and at some point, a mature profitable business. The shift from growth to value is where mispricing opportunities often hide.
