Asset Class Trend Following
Asset class trend following is a strategy that tries to exploit a momentum anomaly between various assets. It uses various moving averages/momentum filters to gain an exposure to an asset class only at the time when there is a higher probability for outperformance with less risk. This strategy has been popularized by Mebane Faber (with risk parity weighting tweaking), one of its main proponents. We present Faber's simple version and links to other similar strategies are in «Other papers» section (also recommended to read).
Fundamental reason
Momentum/trend following filter rules are able to divide time into periods with lower performance (higher volatity/risk) and higher performance (lower volatility/risk). A portfolio of several asset classes with incorporated momentum filter rules could enhance returns and lower risks as this portfolio exploits diversification benefits of low correlation between assets.
Use 5 ETFs (SPY — US stocks, EFA — foreign stocks, BND — bonds, VNQ — REITs, GSG — commodities), equal weight the portfolio. Hold asset class ETF only when it is over its 10 month Simple Moving Average, otherwise stay in cash.
