Relative Strength Strategies for Investing
First Draft April 2010
ABSTRACT
The purpose of this paper is to present simple quantitative methods that improve risk-adjusted returns for investing in US equity sector and global asset class portfolios. A relative strength model is tested on the French-Fama US equity sector data back to the 1920s that results in increased absolute returns with equity-like risk. The relative strength portfolios outperform the buy and hold benchmark in approximately 70% of all years and returns are persistent across time. The addition of a trendfollowing parameter to dynamically hedge the portfolio decreases both volatility and drawdown. The relative strength model is then tested across a portfolio of global asset classes with supporting results.
