Historical Performance and Market Cycles
Understanding the historical performance of factor premiums provides crucial context for interpreting current market conditions. This section examines how factors have performed across different market environments.
Long-Term Factor Returns
The Kenneth R. French Data Library provides factor returns dating back to 1926, offering nearly a century of data for analysis. Key historical observations include:
| Factor | Average Annual Premium (1926-2023) | Standard Deviation |
|---|---|---|
| Market (Mkt-RF) | ~8.0% | ~20% |
| Size (SMB) | ~2.0% | ~12% |
| Value (HML) | ~3.5% | ~14% |
| Profitability (RMW) | ~3.0% | ~8% |
| Investment (CMA) | ~3.0% | ~7% |
Caution: These long-term averages mask enormous variation over shorter periods. Factors can underperform for a decade or more, testing the patience of even committed factor investors.
Value Factor Cycles
The value factor has experienced several extended periods of significant under- and outperformance:
- 1926-1940s: Strong value premium during and after the Great Depression, as distressed stocks recovered.
- 1970s: Excellent decade for value as "Nifty Fifty" growth stocks collapsed.
- Late 1990s: Value severely underperformed during the dot-com bubble.
- 2000-2007: Strong value recovery after the tech bubble burst.
- 2007-2020: Extended period of value underperformance, reaching historic extremes by 2020.
- 2021-2022: Value showed signs of recovery amid rising interest rates.
Factor Correlations
One benefit of multi-factor investing is diversification. Factors have varying correlations with each other:
- Value and Profitability: Negatively correlated. Cheap stocks are often cheap because they're less profitable.
- Value and Momentum: Negatively correlated. Value stocks are often recent underperformers.
- Size and Value: Modestly positive correlation, especially in down markets.
- Profitability and Investment: Positive correlation. Profitable firms tend to invest less aggressively.
Factor Performance During Crises
Factor behavior during market crises is particularly important for risk management:
2008 Financial Crisis: Value stocks suffered significant losses, particularly financial value stocks. Quality and low volatility factors provided better protection.
2020 COVID Crash: Value underperformed sharply in the initial crash, as investors fled to growth and quality names. This exacerbated the already extended drawdown in value.
2022 Rising Rates: Value significantly outperformed as rising interest rates hurt growth stock valuations. This demonstrated value's potential as a hedge against rate increases.
