Momentum investing — buying stocks that have been going up and avoiding those going down — sounds too simple to work. Yet it’s one of the most well-documented factors in academic finance, and the Nifty 200 Momentum 30 index has returned 22% CAGR over 10 years versus Nifty 50’s 12%. Here’s how to implement it.
The Science Behind Momentum
Momentum works because of behavioral biases: investors underreact to positive information initially, then overreact as trends become obvious. This creates predictable price patterns over 3-12 month horizons. Nobel laureate Eugene Fama acknowledged momentum as an “anomaly” that challenges market efficiency.
