Cryptocurrency markets have long puzzled investors and researchers alike. Without standardized valuation models or consistent fundamental data, traders often turn to price action and technical indicators to guide their decisions. In a groundbreaking study, researchers Christian Fieberg, Gerrit Liedtke, Thorsten Poddig, Thomas Walker, and Adam Zaremba introduce CTREND, a novel trend factor that aggregates price and volume signals across multiple time horizons to predict cryptocurrency returns with remarkable accuracy.
Using data from over 3,000 coins between 2015 and 2022, the team leverages machine learning techniques to distill insights from 28 technical indicators, including moving averages, momentum oscillators, volume metrics, and volatility measures. The result? A robust, cross-sectional signal that outperforms existing cryptocurrency pricing models and withstands transaction costs, market states, and alternative research designs.
The Power of Technical Signals in Crypto
Unlike traditional equities, where earnings, dividends, and macroeconomic factors inform pricing, cryptocurrencies operate in an environment rich in speculation and low on fundamentals. This scarcity pushes investors toward price-based inference—interpreting trends as signals of adoption, sentiment, or future value.

A growing body of evidence supports the predictive power of technical analysis in crypto markets. Studies show that strategies based on moving averages, relative strength, and volume trends can generate statistically significant returns. However, most prior work focuses on individual coins or isolated indicators. CTREND changes this by synthesizing a wide array of signals into one unified predictive framework.
Why Aggregation Matters
Single indicators are noisy. A coin might appear overbought on the RSI but still rally due to strong volume momentum or breakout patterns. By combining multiple signals—each capturing different aspects of market behavior—CTREND reduces noise and enhances signal clarity.
The methodology uses the Combined Elastic Net (C-ENet) approach to select and weight the most informative forecasts from univariate regressions. This data-driven selection avoids arbitrary choices and adapts dynamically to shifting market conditions.
How CTREND Works: From Data to Prediction
The construction of CTREND follows a rigorous three-step process:
- Data Collection & Cleaning
Prices, volumes, and market caps are sourced from CoinMarketCap. Observations are filtered for validity: missing data is excluded, extreme outliers are truncated (top and bottom 0.5%), and only coins with market caps above $1 million are included. Technical Indicator Calculation
The model computes 28 widely used indicators across four categories:- Momentum Oscillators: RSI, Stochastic (K/D), StochRSI, CCI
- Moving Averages: Simple (3–200 days), MACD, MACD signal line
- Volume Indicators: Volume SMAs, VolMACD, Chaikin Money Flow
- Volatility Measures: Bollinger Bands (upper/mid/lower), Bollinger Width
- Signal Aggregation via Machine Learning
Using cross-sectional Fama-MacBeth regressions combined with elastic net regularization, the model generates a weekly forecast for each coin’s return based on its technical profile.
This approach ensures that CTREND isn’t reliant on any single indicator but instead captures collective market intelligence embedded in diverse technical signals.
CTREND Delivers Strong Risk-Adjusted Returns
When sorted into quintile portfolios—longing the top 20% of coins by CTREND score and shorting the bottom 20%—the strategy yields an average 3.87% weekly return, with a Sharpe ratio of 1.94. Even more impressively:
- The strategy remains profitable after adjusting for transaction costs (up to 70 bps round-trip).
- Abnormal returns persist across bull and bear markets.
- Performance holds in both high- and low-volatility regimes.
| Metric | Value |
|---|---|
| Weekly Return (Long-Short) | 3.87% |
| Annualized Sharpe Ratio | 1.94 |
| LTW-Adjusted Alpha | 2.62% per week |
| Holding Period Significance | Up to 4 weeks |
These results suggest that CTREND taps into a persistent behavioral or structural inefficiency in crypto markets—one not fully captured by momentum, size, or market risk factors.
FAQ: Understanding CTREND’s Edge
Q: Is CTREND just another momentum strategy?
A: While correlated with momentum (CMOM beta = 0.79), CTREND generates significant alpha even after controlling for CMOM. It extracts information beyond simple past returns by integrating volume, volatility, and oscillator dynamics.
Q: Does it work only in small-cap altcoins?
A: No. The effect is strongest among large and liquid coins. When restricted to the top 100 cryptos by market cap, the strategy still earns over 2.45% weekly, net of trading costs.
Q: How sensitive is CTREND to transaction costs?
A: Remarkably resilient. With conservative assumptions (30–40 bps per trade), net returns remain above 2.35% weekly. The breakeven cost is 141 bps—one of the highest among known anomalies.
Q: Can it be used practically by retail traders?
A: Yes. While turnover is high (~68% weekly), returns hold up under less frequent rebalancing (e.g., biweekly or monthly). Automation tools make implementation feasible.
Robustness Across Market Conditions
One of CTREND’s most compelling features is its stability.
- Over time: Performance remains strong post-2018 despite increased market maturity.
- Across volatility regimes: Higher returns in calm markets suggest it's not merely capturing panic or euphoria.
- In bear markets: Delivers 3.25% weekly return, outperforming traditional momentum strategies that often fail during downturns.
Even when subjected to 53,920 alternative research designs—varying sample filters, estimation windows, weighting schemes—the CTREND factor maintains superior risk-adjusted performance in nearly 80% of cases.

Outperforming Existing Asset Pricing Models
Traditional models like the cryptocurrency CAPM (CCAPM) or Liu-Tsyvinski-Wu (LTW) three-factor model struggle to explain known anomalies. But a new model incorporating CMKT + CSMB + CTREND significantly improves explanatory power:
- Average absolute alpha drops from 2.69% (CCAPM) to 0.68%
- Only two anomalies remain significant vs. twenty under CCAPM
- GRS test p-value rises to 8.02%, indicating no strong rejection of model validity
Notably, this model explains momentum itself—rendering the CMOM factor redundant. This suggests that what we call "momentum" in crypto may actually be a subset of broader trend-following behavior captured more fully by CTREND.
Practical Implications for Investors
For active traders and quantitative funds, CTREND offers a powerful edge:
- High-frequency applicability: Weekly rebalancing works well
- Scalability: Effective even in top-tier assets like Bitcoin, Ethereum, BNB
- Cost efficiency: Profits survive real-world trading frictions
- Flexibility: Can be adapted to longer horizons without complete decay
Moreover, because the signal derives from publicly available price and volume data, it’s accessible to all—not just institutional players.
FAQ: Implementation Tips
Q: What tools can I use to implement CTREND?
A: Python libraries like pandas, scikit-learn, and ccxt allow full replication. Key steps include data fetching, indicator calculation, elastic net modeling, and portfolio sorting.
Q: Should I go long/short or just go long high-score coins?
A: Both work—but long-short enhances returns and hedges market risk. For conservative investors, a long-only version still beats benchmarks.
Q: Are there risks I should watch for?
A: Yes. Like all trend-following systems, CTREND may underperform during sharp reversals or black swan events. Diversification and position sizing remain critical.
