What Is It?

Trend following identifies and rides sustained price movements across markets, profiting from the tendency of markets to exhibit persistence—winners keep winning and losers keep losing for extended periods. Unlike mean reversion strategies that bet against extremes, trend followers buy assets rising in price and sell assets falling in price, capturing directional moves. The strategy operates across time horizons from days to months, using systematic rules to enter when trends begin and exit when they end.

Origin

Trend following was formalized in the 1970s by commodity trading advisors (CTAs) trading futures markets. Legendary traders like Richard Dennis, who famously taught the "Turtle Traders," demonstrated that trend following could be systematized and taught. The 1980s saw the emergence of dedicated CTA funds, while the 1990s and 2000s brought trend following to equities, currencies, and fixed income. Managers like AQR, Winton, and Trendstat became institutional leaders. The strategy's legendary performance during the 2008 financial crisis cemented its reputation as a source of "crisis alpha."

Why It Matters

Trend following provides crisis alpha and diversification, generating positive returns during market dislocations when traditional assets suffer. The strategy is uncorrelated with equities over long periods while offering convexity—trend followers tend to profit during extreme market moves in either direction. For institutional portfolios dominated by long-only equity risk, trend following offers valuable diversification, improving risk-adjusted returns through negative correlation during drawdowns. The strategy exploits a fundamental market anomaly: prices exhibit persistence rather than random walk behavior.

Market Mechanics

Trend following models use moving averages, breakouts, or channel systems to identify directional moves, combined with volatility targeting for position sizing. Common entry signals include price crossing above a 50-day or 200-day moving average, or breaking out to new 20-day or 55-day highs. Exit signals occur when prices reverse through moving averages or hit trailing stops. Risk management involves volatility targeting—reducing position sizes when volatility increases to maintain constant risk exposure. The strategy trades across diverse markets (equities, bonds, currencies, commodities) to capture whatever trends emerge.

How It Behaves

Trend following performs best during prolonged directional markets and struggles during choppy, range-bound conditions where false signals generate losses. The strategy exhibits positive skew—many small losses from failed breakout attempts offset by occasional large gains from sustained trends. Returns are concentrated in crisis periods when trends are strongest and most persistent. Trend following faces lengthy drawdowns during trendless markets, requiring psychological endurance and institutional commitment to maintain allocations when performance lags. The strategy benefits from diversification across markets since trends emerge asynchronously in different asset classes.

Key Data to Watch

  • Trend strength metrics: Moving average slopes, ADX (Average Directional Index), or linear regression R-squared
  • Drawdown duration: Length of losing periods, often lasting months during trendless markets
  • Correlation to equities: Trend following typically shows negative correlation during crisis periods
  • Volatility-adjusted position sizes: Ensuring risk remains constant as market volatility changes
  • Breakout success rate: Percentage of entry signals that develop into sustained trends
  • Time to recovery: How quickly the strategy recovers drawdowns when trends resume
  • Cross-asset trend dispersion: Whether trends exist across multiple markets simultaneously
  • Market regime indicators: Measures distinguishing trending from range-bound environments

Institutional Behavior

Large CTAs (Commodity Trading Advisors) run multi-asset trend-following programs with billions in assets under management. AQR, Man AHL, and Winton are leading institutional trend followers, combining systematic rules with sophisticated risk management. Pension funds and endowments allocate to trend following for crisis risk mitigation and diversification. The strategy has evolved from simple moving average crossovers to machine learning-enhanced signal generation and multi-factor trend identification. Institutional trend followers trade 100+ markets across asset classes, dynamically adjusting position sizes based on volatility and correlation.

Key Takeaways

Trend following profits from market persistence—the tendency of prices to continue moving in the same direction for extended periods. The strategy provides unique diversification benefits through crisis alpha and low correlation to traditional assets. However, trend following requires patience and psychological resilience—most trades lose money, and profitable trends occur infrequently. Success demands disciplined adherence to systematic rules without discretionary overrides during drawdowns. The strategy is not about prediction but about participation: trend followers don't know which trends will persist, but they ensure they participate in the ones that do. For investors seeking returns uncorrelated with equity markets and particularly valuable during crises, trend following offers a compelling, if occasionally frustrating, alternative.
