One of the most important lessons for any investor to understand is that factor performance is inherently cyclical. Just as economic and market cycles rotate through phases of expansion and contraction, investment factors — such as value, momentum, quality, volatility, and size — experience alternating periods of strength and weakness.
Recognizing and respecting these cycles may be beneficial to set realistic expectations, maintain discipline, and build more resilient multi-factor portfolios.
Why Factor Performance Cycles Occur
Factors reflect broad patterns in investor behavior, market structure, and economic conditions. These drivers are not static — when market sentiment, policy, or growth expectations shift, the factors rewarded by investors shift as well.
The following forces shape these cycles:
- Market Regimes: Different stages of the business cycle favor different factors. Value and size often outperform in early expansions when growth accelerates, while quality and volatility tend to lead during slowdowns or recessions.
- Investor Behavior: Behavioral biases. — such as herding or overreaction — can amplify factor trends. For instance, momentum thrives when investors chase performance, but it can reverse sharply when sentiment shifts.
- Market Dynamics: Changes in interest rates, inflation, and liquidity conditions can influence factor spreads. For example, rising rates may support value stocks, while periods of low volatility can compress premiums across multiple styles.
These dynamics indicate that factor performance can vary across different market environments.
The Challenge of Timing Factor Exposures
Research and market experience show that factor leadership changes over time, sometimes gradually, sometimes abruptly. Although factor cycles are well documented, successfully timing them remains extremely difficult.
In practice, cycles often turn unpredictably and faster than models anticipate. Investors who attempt to shift exposures reactively — by chasing recent winners or abandoning lagging factors — risk locking in losses and missing subsequent recoveries.
Instead, many professionals favor maintaining strategic, diversified factor allocations rather than tactical timing. This approach accepts that while individual factors may lag temporarily, a well-constructed combination can smooth the overall return path over time.
The Importance of Diversification Across Factors
Because factor cycles" rarely move in perfect sync":https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3014521, combining multiple factors can provide substantial diversification benefits.
- Complementarity: Pro-cyclical factors like value and momentum often perform differently from defensive ones like quality or volatility. When one style underperforms, another may offset the shortfall.
- Reduced Volatility: Blending uncorrelated factor exposures can reduce portfolio drawdowns and make returns more consistent across market phases.
- Long-Term Balance: Over extended horizons, a diversified multi-factor approach tends to capture the structural risk premia of each factor while mitigating the impact of short-term cyclicality.
Diversification is one approach that can help investors manage the effects of factor rotation over time.
Expect Rotation, Build Resilience
The cyclical nature of factor performance is basically inevitable. Each factor reflects different sources of risk and investor behavior, and their alternating leadership contributes to market efficiency. By accepting these cycles, diversifying across multiple factors, and maintaining a disciplined, long-term approach, investors can use factor investing not as a tool for short-term prediction, but as a framework for building more durable, adaptive portfolios.
In short, understanding factor cycles is less about forecasting the next leader and more about constructing portfolios resilient enough to endure — and potentially benefit from — their inevitable rotation.
