Enduring Periods of Underperformance

From 2010 to 2020, value investing underperformed growth by a historically large margin. An investor who believed in value principles and disciplined selection methods faced a decade of watching technology and growth stocks deliver superior returns while their portfolio stagnated.

This wasn't a minor inconvenience. For professional managers, a decade of underperformance meant clients leaving, assets under management declining, and compensation evaporating. For retail investors, it meant watching friends brag about tech gains while their boring portfolio produced meager returns. For everyone, it meant years of questioning whether the philosophy was broken, whether the analysis was flawed, whether patience was just another word for stubbornness.

And then 2020-2022 arrived, and value outperformed.

Yet something important happened in that gap. Many investors quit, switched strategies, or pivoted to growth. Their underperformance ended in permanent losses because they couldn't endure temporary underperformance.

Quick Definition: Underperformance is the period when your portfolio or strategy returns less than the broader market index or relevant benchmark, even though your underlying thesis and analysis remain sound. It's not a failure of method—it's a feature of contrarian value investing.

Key Takeaways

• Underperformance is not failure: Value portfolios will periodically underperform because they're out of step with crowd sentiment. This is the mechanism through which value creates opportunities, not evidence that the strategy is broken.
• The psychology of underperformance is the hardest part: Most investors can tolerate absolute losses (down 5% is acceptable). What breaks them is relative underperformance (competitors up 15% while you're down 5%).
• Extended underperformance is normal, not rare: History shows that value strategies have underperformed for multi-year periods with surprising frequency. This is not a recent phenomenon.
• Social proof becomes more powerful as underperformance lengthens: The longer you underperform, the more people will tell you you're wrong. Eventually, you'll start believing them.
• The line between patience and stubbornness erodes under pressure: The longer underperformance lasts, the harder it becomes to distinguish between "my thesis will vindicate" and "I'm just rationalizing."
• Winners are those who endure underperformance without breaking: The investors who retire as legends are not those who were always right. They're those who were contrarian when everyone disagreed, and who maintained conviction through the valley of underperformance.

Why Underperformance Happens

Value investing explicitly seeks stocks the market dislikes. This means value portfolios are constructed from positions the crowd is selling or avoiding. When market sentiment is broadly optimistic, the crowd buys growth and technology. When sentiment shifts to fear, the crowd sells cyclicals and value. Value investors are perpetually out of step.

But why does this create extended underperformance?

Sentiment persistence: Once market sentiment shifts toward growth and away from value, that sentiment can persist for years. Growth stocks attract capital inflows. Fund flows push prices higher. Higher prices attract more capital. This feedback loop is momentum, and momentum can overwhelm fundamentals for surprisingly long periods.

Narrative capture: During value underperformance, a coherent narrative typically emerges: "Value investing is dead. The world has permanently changed. Growth stocks are worth their premium because of network effects/AI/disruption/etc." These narratives become self-fulfilling. Institutions that questioned them look foolish, so they adopt them.

Structural changes in capital flows: From 2010-2020, passive indexing exploded. Passive funds allocate capital proportionally to market cap. This means money flows into the biggest, most expensive stocks regardless of valuation. A portfolio of small, cheap stocks is structurally disadvantaged in an environment where capital flows are passive.

Multiple expansion vs. fundamental earnings: Growth stocks are priced for perfection. If a growth stock grows at 20%, the market might still bid it up because growth is scarce. Conversely, a value stock might be cheap because it's only growing 3%, but if growth accelerates to 5%, the market won't care—growth is no longer rare. Value requires waiting for multiple expansion or for the business to compound earnings toward intrinsic value.

The Historical Precedent

Value underperformance is not unique to 2010-2020. History shows several extended periods:

1973-1983: Value stocks, particularly cheap cyclicals, massively underperformed growth and commodities. A value investor who had accumulated positions in depressed industrials in the early 1970s watched technology stocks soar for a full decade before mean reversion arrived.

1995-2000: The dot-com bubble saw technology and growth stocks detach from fundamentals entirely. Value investors who shorted tech or avoided it got crushed. The positions that saved them were dividends from boring positions held in the early 1990s.

2003-2007: Private equity and credit were the favorites. Value investing in public equities looked stale. Leverage and M&A looked genius.

The pattern is consistent: value underperforms for 5-10 years, then sharply outperforms as mean reversion occurs. The investors who succeed are those patient enough to survive the valley.

The Psychological Toll

Understanding intellectually that underperformance is temporary is different from experiencing it emotionally.

Peer pressure escalates with time: In year 1 of underperformance, you might hear one friend brag about tech gains. In year 3, everyone around you is making money on growth. In year 5, you become the outlier—the cautious dinosaur who "doesn't get it." By year 7, self-doubt is genuine.

The narrative becomes seductive: After 2015, genuinely smart people were arguing that value was dead. They had real reasons: passive flows, intangible assets, software economics. These weren't stupid arguments. Hearing them repeatedly, from credible sources, wearing down conviction is natural.

Regret increases with opportunity cost: A 5% annual underperformance compounds. After 5 years, you've underperformed by roughly 25% cumulatively. The regret—what you could have made if you'd been in growth stocks—becomes acute.

Your identity becomes threatened: If you've defined yourself as a value investor or fundamental analyst, extended underperformance threatens your identity. You're not just wrong about stocks. You're wrong about yourself.

How the Best Investors Have Endured

Buffett's approach: focus on business, not price

Buffett has explicitly stated that he doesn't care about annual returns relative to the S&P 500. He cares about intrinsic value and business quality. If Berkshire underperforms for a period, he views it as the market making a mistake, not Berkshire making a mistake. This allows him to be indifferent to the comparison.

In practice, this means focusing on what he can control (quality of business analysis, capital allocation) and ignoring what he can't (whether technology stocks will continue dominating).

Munger's approach: construct an ecosystem of believers

Charlie Munger surrounded himself with other intelligent people who shared value principles. They'd discuss businesses and markets together. The point wasn't to convince each other. It was to maintain a mental model of rationality in an irrational environment.

He explicitly rejected institutional frameworks that would penalize contrarianism. No benchmarks, no performance comparisons to growth indices. This insulates you from underperformance pressures.

Klarman's approach: maintain a thesis record

Seth Klarman has emphasized the importance of keeping a decision journal—recording your thesis at the time of the investment, not in hindsight. This allows you to separately evaluate whether your analysis was sound (even if outcomes were poor) from whether outcomes were favorable.

This distinction matters enormously. If your analysis was sound but outcomes were bad, that's market risk, not analysis failure. If your analysis was flawed, that's a different problem.

Tepper's approach: position sizing proportional to conviction

David Tepper sizes positions based on conviction, not potential return. When you have very high conviction, you can size larger, which means concentrated underperformance hurts less because concentrated gains compound faster.

When conviction is medium, you size smaller. This means that when you're wrong, the damage is limited. And when you're right, the gain is enough to offset earlier underperformance.

Real-World Examples

Howard Marks through the tech bubble

Marks was famously skeptical of technology valuations in the late 1990s. His fund had significant underperformance for several years as tech rocketed. But Marks didn't change his analysis. He maintained that valuations were unjustifiable. And when 2000 arrived and tech crashed, his fund's defensive positioning meant he suffered less damage while having cash to deploy into depressed assets.

The underperformance period (1996-1999) ended with vindication (2000-2003).

Value investors 2010-2020

Many value-focused hedge funds and mutual funds faced their worst decade on record from 2010-2020. Some closed. Some pivoted to growth. But a few maintained conviction. Adjusted for 2020-2022 bounce, those who maintained conviction captured one of the largest mean reversion rallies in history.

The cost of that patience was years of client calls explaining underperformance. The reward was vindication.

A hypothetical tech skeptic in 2017

Imagine an investor who in 2017 concluded that technology was overvalued and sized a portfolio away from tech. From 2017-2021, they'd experience severe underperformance, missing the explosive gains in Tesla, Apple, Nvidia, and others. But from 2021-2023 (when tech corrected sharply), that underperformance reversal would compound rapidly.

How to Psychologically Survive Underperformance

1. Define success in terms of process, not outcomes

The best investors separate analysis from results. Your analysis can be sound and results can be bad (bad luck). Your analysis can be flawed and results can be good (good luck). Judge yourself on whether your process was rational given available information, not just on whether you made money.

2. Maintain a decision journal

Record your thesis before the investment. Quarterly, compare your predictions to outcomes. This accomplishes two things: (a) you see whether you were actually wrong or just early, and (b) you develop pattern recognition about your own forecasting errors.

3. Construct a peer group of like-minded thinkers

Surround yourself with other thoughtful investors who share your framework. Not for affirmation, but for intellectual honesty. Discuss positions. Debate assumptions. This ecosystem keeps you honest about rationalizations.

4. Reframe underperformance as evidence your thesis is intact

If you're underperforming, it's because the market disagrees with you. The market disagreeing with you is precisely why your positions are cheap. Underperformance is your margin of safety being validated.

5. Calculate the opportunity cost of switching

If you're tempted to abandon a value strategy for growth, calculate the cost. If you've underperformed by 5% annually for 5 years, you're down about 25% cumulatively. To break even, growth must outperform value by roughly 5% annually for another 5 years. Is that what you believe?

6. Set explicit invalidation thresholds

Before entering a value position, define what would make you wrong. Not "if the price falls 50%" but "if the business fundamentally deteriorates in X way." Having explicit thresholds makes underperformance sustainable because you're not permanently locked in.

7. Maintain diversification

A diversified portfolio of undervalued positions will have periods where various parts underperform. But the portfolio as a whole is more likely to contain some positions that perform. This reduces the psychological burden of underperformance—not all positions are simultaneously underwater.

8. Don't measure yourself constantly

Check your portfolio monthly for updates. Check returns quarterly. But don't check daily, and don't compare to growth indices monthly. The more frequently you measure, the more you'll focus on relative performance rather than fundamental progress.

Common Mistakes

Mistake 1: Confusing "underperforming the S&P" with "underperforming the market" The S&P 500 is not the market. It's one index. If your value strategy is outperforming global equities but underperforming large-cap growth, you're not failing. You're succeeding in a specific niche that's out of favor.

Mistake 2: Switching strategies at the precise moment of maximum pain The worst time to switch from value to growth is after value has underperformed for many years. At that point, growth is most expensive and value is cheapest. You're selling low and buying high.

Mistake 3: Assuming underperformance is permanent During 2010-2020, many intelligent analysts concluded that value investing was dead. The environment had fundamentally changed. Technology would always outperform. Within a few years of mean reversion, these same analysts were calling value investing the new hot strategy. Permanent changes are rarer than they feel.

Mistake 4: Abandoning process because of poor outcomes You follow a strict value process. You buy cheap stocks with good fundamentals. But this year, you underperformed. So you abandon the process and "try something new." This ensures you're switching at the wrong times.

Mistake 5: Not distinguishing between thesis failure and market timing Your thesis might be right—a stock will double in five years. But if growth stocks triple in five years and your value stock doubles, you underperformed. The failure was market timing (not predicting growth would dominate), not analysis.

FAQ

Q: How long should you endure underperformance before reconsidering? A: This depends on whether your thesis remains intact. If your analysis is sound but the market disagrees, you can maintain conviction indefinitely. If your analysis is being invalidated by outcomes, you should reconsider much faster.

Q: Should you adjust your strategy if you're underperforming? A: Only if your analysis has changed, not if outcomes have changed. Many investors use underperformance as a signal to switch. This is backwards. Use underperformance as a signal to examine your analysis.

Q: Is it safer to follow your thesis if you have long-term horizon? A: Yes and no. A long-term horizon is necessary for value investing because value requires patience. But a long-term horizon doesn't mean never reconsidering. Monitor your thesis continuously, even if your time horizon is long.

Q: What's the maximum underperformance you should tolerate? A: There's no magic number. But if underperformance is extreme (down 30% while the market is up 30%), that's a signal to investigate whether something fundamental is wrong. It doesn't mean immediately capitulating, but it means serious analysis.

Q: How do you explain underperformance to investors/clients? A: Honestly. Your portfolio is underperforming because it contains positions the market currently dislikes. You believe they're mispriced. Here's your thesis. Here's the thesis remains valid. These are the signals that would prove you wrong.

Q: Should you increase position sizes during underperformance? A: Only if your thesis has gotten better (price is lower, fundamentals are stronger). Don't increase position size simply to average down into losses. That's loss aversion, not contrarianism.

Q: How do professional managers survive underperformance? A: Some don't. Many close funds or pivot to fashionable strategies. Those who do survive typically focus on: (a) creating an edge that justifies the deviation from benchmarks, (b) raising patient capital that won't demand constant outperformance, (c) managing fees aggressively (lower fees reduce the pain of underperformance), and (d) demonstrating long-term results that more than compensate for periods of underperformance.

Related Concepts

Recency bias: The tendency to believe that recent trends will continue. Underperformance seems permanent because it's recent, but historically, it reverses.

Survivorship bias: The bias that leads us to study only the investors who survived underperformance, not those who quit. This makes patience seem wiser than it might be.

Time diversification: The idea that longer time horizons mean lower risk. This is true for systematic risk but not for mispricing. Underperformance can extend indefinitely.

Mean reversion: The statistical tendency for performance to revert to historical averages. This is the mechanism that typically ends periods of value underperformance.

Benchmark risk: The risk that you underperform a benchmark you're measured against. For many professional managers, this is actually more painful than absolute losses.

Summary

Enduring periods of underperformance is perhaps the single greatest test of value investing conviction.

Value investing requires you to be out of step with market sentiment. Being out of step means periods when your returns are worse than the broader market. These periods can last years. They can be psychologically agonizing. Friends will make money. Competitors will outperform. The narrative will shift against you.

Yet underperformance is not failure. It's the price of contrarianism. Every underperforming period creates opportunity—either because your thesis is correct and will eventually be validated, or because it reveals that your thesis is flawed and should be updated.

The investors who succeed are those who can distinguish between these two scenarios quickly enough to act on the distinction. Those who can maintain conviction through underperformance without becoming stubbornly irrational. Those who update their theses when new information warrants while maintaining conviction when the original thesis remains intact.

The psychological capacity to endure this is the core edge of value investing. It can't be learned from a book. It can only be developed through experience, reflection, and deliberate practice.

For institutional investors and professional managers, underperformance creates not just psychological pressure but career risk. The incentive structures of professional investing can directly oppose value investing discipline.
