Momentum Strategy

As elaborated in "What Works Best?", a strategic allocation involving perhaps five to ten equally weighted asset classes available via low-fee exchange-traded funds (ETF) or mutual funds, with periodic rebalancing, is a simple way for individual investors to harvest uncorrelated volatility over the long term. For investors seeking an active (tactical) edge, there is evidence supporting exploitation of intermediate-term momentum of these asset class proxies. Holding a few top-performing funds (rather than just the top fund) combines continuous diversification and momentum.

For the set of strategies described here, we allocate at the end of each month all funds to the top one (Top 1), the equally weighted top two (EW Top 2) or the equally weighted top three (EW Top 3) asset class ETFs from a set of nine, based on total return over the past five months.

Supporting research consists of:

Cumulative Performance

The following chart shows the gross cumulative values of $100,000 initial investments in Top 1, EW Top 2 and EW Top 3 portfolios since the end of August 2006 (when all ETFs considered are first available). The chart includes two benchmarks: buying and holding SPDR S&P 500 (SPY); and, an equally weighted, monthly rebalanced portfolio of all ETFs considered (EW All), indicative of simple diversification benefits.
