How Investors Can Capture Long-Term Growth the Market Overlooks in 2025
In the world of modern investing, long-term growth expectations shape nearly every financial decision, from equity valuations and discounted cash flow models to how analysts estimate a company’s future prospects. Despite this central importance, the investment landscape has long suffered from a lack of clear guidance on how long-term growth should be measured or forecasted. The result is a market that often misprices growth, leaving significant opportunities for investors who know where to look.
A groundbreaking study by Angel Tengulov, Josef Zechner, and Jeffrey Zwiebel, published in 2025, reveals that markets consistently fail to fully incorporate long-term growth expectations into stock valuations. Using decades of historical data, combined with machine learning tools and traditional econometric methods, the research uncovers patterns that investors can use to identify companies poised for sustainable expansion. These insights challenge the long-standing assumption that markets always price growth efficiently—and open the door for disciplined investors to capitalize on overlooked opportunities.
The Hidden Inefficiencies Behind Long-Term Growth Pricing
The study’s central finding is simple but powerful: long-term growth is systematically underpriced. Companies with strong long-term growth characteristics regularly generate abnormal returns, indicating that markets aren’t absorbing this information accurately. This contradicts the efficient market hypothesis and suggests that many investors either ignore or misinterpret long-horizon signals.
Several company and industry characteristics were identified as highly predictive of future long-term growth—yet markets often undervalue them when pricing stocks, creating opportunities for investors who understand these patterns.
- Book-to-market ratios often fail to reflect future revenue expansion.
- Analyst long-term earnings forecasts reliably signal actual long-term growth.
- Companies with strong competitive barriers experience higher and more durable growth.
- High profitability and profit reinvestment correlate strongly with future expansion.
- High leverage reduces growth potential due to bankruptcy risks and financial constraints.
- Smaller and younger firms tend to grow faster than mature incumbents.
Predictable Patterns in Long-Term Growth
Contrary to the belief that growth is largely unpredictable, the researchers found that long-term growth patterns are surprisingly systematic. Using multi-decade datasets, their models explained up to 22% of long-term growth variation—an impressive achievement in forecasting.
Machine learning models revealed nonlinear relationships missed by traditional methods, improving forecasting precision and highlighting structural patterns in how companies expand over time.
- Sales and EBITDA growth over five-year horizons showed significant predictive stability.
- Investment levels, capital expenditures, and external financing often foreshadow growth surges.
- Industries with fewer exits and lower competitive turnover tend to produce stronger long-term performers.
How Investors Can Benefit From Mispriced Growth
The evidence clearly shows that markets do not efficiently incorporate long-term growth expectations. This inefficiency creates an opportunity for investors to generate above-average returns by identifying firms whose growth potential remains underappreciated.
Investors who factor long-term growth into their strategies—beyond traditional valuation metrics—can position themselves ahead of slower-reacting market participants.
- Firms with high forecasted long-term growth but moderate valuations produce strong abnormal returns.
- Growth tends to reward patient investors who hold positions until markets correct undervaluations.
- Smaller-cap firms offer superior opportunities because markets price their growth potential less efficiently.
Why Markets Miss Long-Term Growth Signals
Markets tend to over-focus on short-term earnings cycles, interest rates, or macroeconomic uncertainty, causing long-term structural drivers to be overlooked. Behavioral biases also play a role, as investors frequently underestimate how competitive positioning or reinvestment strategies shape future outcomes.
The study highlights several reasons for this systematic mispricing.
- Short-termism in quarterly reporting culture.
- Analysts prioritizing immediate earnings surprises over five-year outlooks.
- Difficulty valuing intangible assets like technological leadership or brand power.
- Loss aversion making investors hesitant to bet on long-term growth stories.
The Role of Machine Learning in Growth Forecasting
One of the study’s most innovative contributions is the use of machine learning to identify complex predictors of long-term growth. These models analyze thousands of variables, uncovering subtle patterns invisible to traditional analysis. However, they emphasized the risk of overfitting, urging investors to combine machine learning insights with economic intuition.
When applied correctly, these advanced analytics can uncover undervalued companies whose long-term trajectories are poised for significant expansion.
- Machine learning isolates nonlinear trends in profitability, competition, and reinvestment.
- Predictive power improves significantly when combining ML with classical models.
- Wide datasets help reduce noise and identify recurring structural growth patterns.
How to Build a Strategy Around Long-Term Growth Opportunities
Investors seeking to exploit long-term growth mispricing should use a systematic, multi-factor approach. Relying solely on traditional valuation metrics is insufficient, as many high-growth companies do not appear cheap on earnings multiples.
Instead, investors should integrate growth-focused indicators into their strategy to identify mispriced opportunities before the broader market catches up.
- Screen for high-profitability companies with strong reinvestment rates.
- Prioritize firms operating in industries with high barriers to entry.
- Analyze long-term earnings forecasts for consistency and upward revisions.
- Favor companies with flexible balance sheets and moderate leverage.
- Use machine learning outputs to validate growth trajectory signals.
The Importance of Patience and Long-Term Holding
One of the strongest conclusions from the study is that long-term investment horizons are essential for capturing the gains associated with mispriced growth. Markets may take years to correct undervaluations, but patient investors are rewarded with returns that exceed benchmark averages.
The findings reinforce that short-term volatility should not deter investors from pursuing long-term growth opportunities grounded in strong fundamentals.
- Abnormal returns materialize over multi-year horizons.
- Market cycles often mask growing competitive strengths until inflection points.
- Long-term growth stocks are often misunderstood early in their trajectory.
Market Inefficiency and the Adaptive Markets Hypothesis
The research aligns with Andrew Lo’s adaptive markets hypothesis, which argues that markets evolve as participants learn and adapt—but are not always efficient. While inefficiencies may shrink over time, long-term growth mispricing continues to persist due to behavioral biases and analytical limitations.
The study suggests that professional investors may increasingly incorporate these insights, but opportunities will still exist for skilled individuals who apply systematic frameworks.
- Markets adjust but do not eliminate all inefficiencies.
- Structural biases mean long-term growth is chronically underpriced.
- Early adopters of this approach may benefit before widespread implementation.
Conclusion
The research by Tengulov, Zechner, and Zwiebel offers one of the most comprehensive analyses of long-term growth expectations in modern finance. The evidence is clear: markets often fail to accurately price long-term growth, creating substantial opportunities for investors who know how to identify high-potential firms before the rest of the market catches up.
By adopting a systematic framework—one that blends financial fundamentals, competitive analysis, and advanced data methods—investors can position themselves to benefit from growth mispricing in 2025 and beyond. Patience, discipline, and a long-term mindset remain crucial, but the rewards can be significant for those willing to look beyond the short-term noise.
