Factor Investing
Tilt a diversified portfolio toward proven return drivers like value, size, and momentum.
How it works
Factor investing systematically harvests characteristics that academic research links to higher long-run returns: value (cheap), momentum (trending), size (small), quality (profitable), and low volatility. Instead of picking individual stocks, you build rules-based baskets tilted toward these factors, often several at once so their uneven cycles offset each other. It sits between passive indexing and active management, sometimes called 'smart beta.' The premise is that factor premia are compensation for risk or persistent behavioral errors, and that disciplined, diversified exposure captures them cheaply. Because any single factor can underperform for years, multi-factor blending and patience are central to the approach.
