Invesco explores how traditional risk metrics can mislead investors and introduces “Internal Portfolio Risk” as a better way to understand true return potential in a low-rate, low-volatility world. The paper challenges the idea that low volatility equals low risk and suggests returns depend more on position-level risk than portfolio-level smoothness.

Key Takeaways
Volatility Misrepresents Risk: Portfolios with similar volatility (~10–15%) can have materially different internal risks, meaning standard deviation alone may understate true return-driving exposures.
Diversification Masks Exposure: Splitting risk across multiple assets can reduce observed volatility by 30–50% without reducing underlying risk taken to generate returns.
Return Driven By Selection: Long-run outcomes depend on manager skill and position selection, not volatility, with internal risk levels ultimately determining return magnitude over time.
