Momentum-Based Sector ETF Rotation: A Moving Average Crossover Approach

A pure momentum-based approach to sector rotation offers a effective and objective way to stay on the right side of the market's strongest trends. This article outlines a sector rotation strategy that uses a moving average crossover system to identify and trade the most effective sector moves.
