Cryptocurrencies, particularly Bitcoin, have captivated global attention over the past decade. Their meteoric price movements, speculative appeal, and technological innovation have drawn interest from investors, regulators, and academics alike. While much research has explored cryptocurrency volatility, hedging benefits, and market inefficiencies, relatively little has focused on the behavioral and technical trading anomalies that may influence returns—until now.
This article investigates the MAX momentum effect in the cryptocurrency market—a phenomenon where assets with extreme positive returns in the prior month continue to outperform in the following period. Unlike traditional financial markets, where high maximum daily returns (MAX) typically predict lower future returns due to investor overreaction and mispricing, cryptocurrencies appear to follow a different pattern: one of momentum persistence.
By analyzing a comprehensive dataset of tradable cryptocurrencies from January 2014 to June 2020, we uncover robust evidence of a positive MAX momentum effect, suggesting that extreme performance tends to repeat rather than reverse. This finding challenges conventional asset pricing logic and opens new avenues for strategic trading in digital assets.
Understanding the MAX Effect
The MAX effect was first identified by Bali, Cakici, and Whitelaw (2011) in U.S. equities. It refers to the anomaly where stocks exhibiting the highest maximum daily return over the past month (referred to as MAX) tend to underperform in the subsequent month. This underperformance is attributed to investor preference for lottery-like assets—securities with high positive skewness that attract speculative buying, leading to temporary overpricing.
In traditional markets, this creates a reversal pattern: after a spike in price driven by speculation, prices tend to correct downward as rationality reasserts itself. However, in the highly speculative and sentiment-driven cryptocurrency market, this dynamic appears inverted.

Why Cryptocurrencies Are Different
Several characteristics make cryptocurrencies a unique environment for studying extreme return behavior:
- High volatility: Cryptocurrencies experience price swings far exceeding those of traditional assets.
- Positive skewness: Most digital assets exhibit right-skewed return distributions—meaning large upward moves are more common than large downward ones.
- Speculative investor base: Evidence suggests crypto investors display risk-seeking behavior akin to lottery players.
- 24/7 trading: Unlike stock markets, crypto markets never close, amplifying reaction speed and momentum.
A histogram of skewness across over 2,500 cryptocurrencies reveals that the majority display positive skew, reinforcing the idea that these assets function similarly to lottery tickets in investors' minds.
Moreover, studies have shown that:
- Bitcoin price movements correlate with gambling activity (Conlon & McGee, 2020).
- Crypto traders exhibit higher risk appetite and behavioral biases (Lammer et al., 2019).
- Investors increase leverage and speculative trading across asset classes when active in crypto (Pelster et al., 2019).
These findings collectively support the hypothesis that behavioral finance plays a dominant role in cryptocurrency pricing.
Methodology and Data
Our analysis uses daily closing price data from CoinMarketCap, covering all actively traded cryptocurrencies between January 1, 2014, and June 30, 2020. Prices are aggregated using a weighted average across multiple exchanges to ensure accuracy and reduce arbitrage distortions.
We define MAX(N) as the highest daily return for a given cryptocurrency in month t. At the end of each month, we sort all coins into deciles based on their MAX value and measure their performance in the first week of the following month.
Using weekly returns instead of monthly allows for greater statistical precision due to the short history and high volatility of crypto assets.
We employ both:
- Single-sorted portfolio analysis
- Double-sorted portfolios, controlling for size, momentum, illiquidity, price, and trading volume
This multi-layered approach ensures robustness against alternative explanations.
Key Findings: The Emergence of MAX Momentum
Contrary to findings in traditional equity markets, our results show a clear positive MAX momentum effect:
- Cryptocurrencies with the highest MAX values in month t significantly outperform those with the lowest MAX values in week t+1.
- The return spread between high-MAX and low-MAX portfolios exceeds 1% per week on an equal-weighted basis.
- This effect persists even after adjusting for market risk, size, momentum, and liquidity factors.
Behavioral Drivers Behind MAX Momentum
The anomaly is strongest during:
- Market upturns: Bullish sentiment reinforces momentum chasing.
- Periods of low investor sentiment: When fear prevails, extreme performers stand out and attract contrarian attention.
- Among underpriced assets: Using Stambaugh et al. (2015)'s mispricing framework, we find the MAX premium is largest for coins deemed most undervalued—suggesting rational investors may be late to recognize breakout potential.

Robustness Checks
To ensure our findings are not artifacts of sample selection or measurement bias, we conduct several robustness tests:
- Longer holding periods: The MAX momentum effect remains significant over 2-week and 4-week horizons.
- Alternative MAX measures: Results hold when using median or average of top 3 daily returns instead of single-day maximum.
- Large-cap filter: Excluding cryptocurrencies with market caps below $500,000 does not diminish the effect.
- Minimum history requirement: Restricting the sample to coins with at least two years of trading history confirms durability.
Importantly, the MAX momentum premium is:
- Independent of idiosyncratic volatility
- Higher than skewness-based premiums
- Not driven by micro-cap or illiquid tokens
This indicates the effect is economically meaningful and not merely a proxy for known risk factors.
Implications for Traders and Investors
For active traders, the MAX momentum effect presents a compelling strategy:
- Monitor monthly maximum returns across major cryptocurrencies.
- Allocate capital toward those with recent extreme gains.
- Target short-to-medium-term holding periods (1–4 weeks).
However, caution is warranted:
- Momentum can reverse suddenly during market corrections.
- High volatility demands strict risk management.
Portfolio construction should integrate MAX signals alongside other technical and sentiment indicators to improve timing and reduce drawdowns.
Frequently Asked Questions (FAQ)
Q: What exactly is the MAX effect in financial markets?
A: The MAX effect traditionally refers to the tendency of stocks with high maximum daily returns over a period to underperform in the future. It's linked to investor overreaction and overpricing of lottery-like stocks.
Q: Why does cryptocurrency show a momentum version of MAX instead of reversal?
A: Due to persistent speculation, FOMO (fear of missing out), and slow information diffusion in crypto markets, extreme gains often signal strength rather than exhaustion—encouraging further buying pressure.
Q: Can retail traders apply the MAX momentum strategy effectively?
A: Yes, but only with disciplined execution. The strategy works best when combined with volume analysis and market regime filters (e.g., applying it only during bull phases).
Q: Is the MAX momentum effect consistent across all cryptocurrencies?
A: No—it’s strongest among larger, more liquid coins and weakest in very small or inactive tokens. Market cap and trading history matter.
Q: How does investor sentiment affect MAX momentum?
A: Surprisingly, the effect intensifies during periods of low sentiment. After broad pessimism, extreme performers attract attention as potential turnaround candidates.
Q: Does this mean traditional finance models don’t work in crypto?
A: Not entirely—but behavioral models often explain crypto price dynamics better than classical mean-variance frameworks due to high speculation and skewness.
Conclusion
This study provides compelling evidence of a MAX momentum effect in cryptocurrency markets—a reversal of the traditional MAX anomaly seen in equities. Rather than reversing after extreme gains, top-performing cryptos tend to keep rising in the short term.
