What is Factor Investing? A Data-Driven Strategy to Boost Returns
Factor investing is a powerful and systematic investment approach that targets specific, proven drivers of return. Instead of relying on market timing or individual stock picking, factor investing focuses on quantifiable characteristics, or “factors”, that influence an asset’s risk and return profile.
Whether you’re a beginner or an experienced investor, understanding factor investing can help you make smarter, more strategic portfolio decisions.
What Is Factor Investing?
Factor investing is a research-backed approach that selects securities based on attributes statistically linked to long-term performance. These attributes, or factors, help explain why certain stocks outperform others.
Common Style Factors in Factor Investing
Here are the most widely used style factors in equity investing:
1. Value
Seeks undervalued stocks (e.g., low P/E or P/B ratios)
Historically strong performance during economic recovery periods
2. Momentum
Focuses on recent winners—stocks with upward price trends
Based on behavioral finance principles
3. Size
Emphasizes small-cap stocks, which historically outperform large caps
4. Quality
Selects companies with stable earnings, low debt, and high return on equity
5. Low Volatility
Targets stocks with low price fluctuations
Aims for smoother returns in volatile markets
Types of Factors
Factor investing is typically divided into two main categories:
1. Macro Factors
These affect broad asset class returns and include:
Economic growth
Inflation
Interest rates
Liquidity
Volatility
2. Style (Micro) Factors
These explain returns within asset classes (e.g., equities or bonds). Common style factors include:
| Factor | Description |
|---|---|
| Value | Stocks that are undervalued relative to fundamentals (e.g., low P/E ratios) |
| Momentum | Stocks with strong recent performance tend to continue to outperform |
| Size | Smaller companies often outperform larger ones over time (small-cap premium) |
| Quality | High profitability, stable earnings, and strong balance sheets |
| Low Volatility | Lower-risk stocks that outperform on a risk-adjusted basis |
| Dividend Yield | Companies with consistent and high dividend payments |
Macro vs. Style Factors
| Type | Examples | Scope |
|---|---|---|
| Macro Factors | Inflation, interest rates, growth | Broad market impact |
| Style Factors | Value, momentum, size, quality | Individual security level |
