Analyse active strategies built on factor exposures, including the reasoning behind them and the steps involved
The idea
Factor-based active strategies seek excess return by holding deliberate exposures to rewarded factors such as value, size, momentum, quality or low volatility, and by varying those exposures over time. The process defines each factor, often as a hedged portfolio long the top-ranked and short the bottom-ranked stocks, tests its historical premium, then combines factors, either with fixed weights, by equalising risk contributions (risk parity) or by timing them with valuation or regime signals. Risks include crowding, sharp reversals, unintended exposures when factors are correlated, and data-mining. Since static premia are cheap, the manager's value added should be judged against a benchmark that already contains them. The trap is paying active fees for returns a low-cost smart-beta product could deliver.
