This strategy applies a long term timing rule over each asset in a properly planned asset allocation portfolio. It reduces the overall portfolio risk while still maintaining (or even increasing) the return.

This strategy is based on Mebane T. Faber's article in seekingalpha.com. It uses a 10 month simple moving average in each asset in the portfolio. A so called Endowment model portfolio is maintained here. This strategy shows that by applying market timing as simple as a moving average could enhance a portfolio's risk adjusted return while avoiding big loss during a market crisis such as the one in 2008. Notice by using market timing, one could choose a once considered 'risky' long term treasury bond in place of the fixed income asset.
