Growth investing, as a discipline distinct from other equity approaches, focuses on companies whose earnings and revenues are expected to grow at rates materially above the market average. The idea sounds simple; the practice has become one of the most complex and consequential branches of modern equity investing, particularly since the 2010s when growth strategies produced returns far outpacing value strategies for the first sustained decade in modern market history.
The core proposition
A growth investor's return comes from two sources: the growth of the underlying business, and any change in the multiple the market pays for that growth. A company whose earnings grow 15% per year for a decade will, holding the multiple constant, produce a stock return roughly matching the earnings growth. If the multiple expands during the period (from, say, 20x to 30x), the total return is materially higher. If the multiple contracts (from 30x to 20x), the return can be substantially below the earnings growth rate — even negative in extreme cases.
This decomposition — growth of the business plus change in the multiple — is the entire mechanic. Understanding both halves is essential to growth investing; focusing only on the business growth without regard to the multiple has produced some of the most consequential drawdowns in modern equity history.
Why growth premiums exist
The academic finance literature has documented that stocks with high expected growth rates trade at higher multiples than stocks with low expected growth rates. The premium reflects two things: the value of future cash flows that grow (rather than staying flat), and the option-like nature of a growing business (which can accelerate or maintain its growth trajectory over long periods).
The size of the premium is not constant over time. It expands when growth is scarce (or when interest rates are low, making long-duration cash flows more valuable) and contracts when growth is abundant (or when interest rates rise). The 2010s produced the largest sustained expansion of the growth premium in modern history; the 2022 rate shock produced its sharpest recent compression.
The 2010s environment
For roughly a decade after the 2008 financial crisis, growth stocks meaningfully outperformed value stocks in the US. The gap was one of the largest in the record. Multiple explanations have been offered — ultra-low interest rates making long-duration growth more valuable, the emergence of software and internet businesses with genuine economies of scale, the deep and persistent underperformance of the industries that dominated value indices — and the truth is probably a combination.
What is clear in hindsight is that "the growth trade" was not one thing. It was several overlapping bets: on the specific companies that grew (Alphabet, Amazon, Netflix, Meta), on the technology sector broadly, on the persistence of low rates, and on the market's willingness to pay expanding multiples for growth stories. When the environment shifted in 2022 — rates rose, some growth stories disappointed, the multiples compressed — the compound effect was much larger than any single component had been.
The 2022 correction and its lessons
The 2022 growth-stock correction was severe. Cathie Wood's ARK Innovation ETF, a widely-owned proxy for "high-conviction growth," fell more than 60% peak-to-trough. Many individual former-highfliers fell 70–90%. The correction was concentrated in the higher-multiple, lower-current-profitability end of the growth spectrum; more established growth companies with strong current cash flow held up substantially better.
The lesson embedded in the correction is that the "duration" of a stock — the weighted average time to expected cash flows — is one of the most under-appreciated risk exposures in growth investing. A high-multiple company whose value depends heavily on cash flows a decade or more in the future is much more sensitive to rate changes than a similarly-multiple company whose current cash flow already justifies the multiple. Both may be called "growth stocks," but their behaviour in a rate shock is very different.
The three archetypes
Not all growth stocks are the same. Three broad archetypes describe most of the category.
Compounders. Established companies with defensible market positions, steady 10–15% revenue growth, expanding margins, and strong free cash flow. Examples over time have included Costco, Microsoft (post-Nadella), Visa, Mastercard. These companies deliver "growth" but their return profiles are relatively modest and less volatile than the higher-conviction growth categories.
High-multiple growth. Faster-growing companies whose current profitability is either modest or absent, whose multiples reflect expectations of substantial future cash flow. Examples over time have included many software-as-a-service companies. These are more sensitive to interest-rate changes and to any disappointment in the growth trajectory.
Story stocks. Companies whose current fundamentals do not clearly justify their multiples, whose valuation rests on a specific narrative about future transformation. These can be extraordinary winners or catastrophic losers, often within the same company over different periods. Position sizing on story stocks requires a different mental model from the other two archetypes.
What connects the three is the growth focus; what separates them is the durability and visibility of the underlying cash flow. The distinctions matter enormously for portfolio construction.
The under-discussed risk
The risk that most under-discussed in growth investing is not that a specific company will disappoint; it is that the market's willingness to pay high multiples for growth stories can change independently of the underlying businesses. A collection of good growth stocks can produce very poor returns for years if the multiple compression exceeds the earnings growth.
The 2000–2003 tech bear market is the classic case. Many of the companies that fell 60–90% in that period continued to grow their revenues and earnings — the businesses were fine. What compressed was the market's willingness to pay 40–100x for their growth. The subsequent recovery for many of those companies took years, not because the businesses failed but because the multiples had to rebuild from much lower starting points.
The rule to internalise
Growth investing decomposes into two bets: on the business growth, and on the multiple the market will pay. Focusing only on the business without regard to the multiple has produced many of the most consequential drawdowns in equity history. The best growth investors have historically been the ones who could distinguish between growth that was cheap (multiple justified by fundamentals) and growth that was expensive (multiple dependent on rare macro conditions or ever-optimistic assumptions). The distinction is not always obvious, but the investors who missed it in each era paid substantially for the miss.
