Eighties nostalgia?
We constructed two lengthy portfolios within the S&P 500 when it traded above its shifting common and shorted it when it traded beneath. One portfolio is constructed on a 50-day shifting common, and the opposite on a 200-day shifting common.
As a technique, shopping for the market on days when it crosses the 50-day shifting common generated a mean each day return of between 0.11% and 0.18% throughout the six a long time surveyed, with the best mark within the 80s. Shopping for the market on days when it fell beneath the shifting common resulted in common each day returns of between -0.14% and -0.28, with the 80s additionally accounting for the most important losses.

This implies an extra efficiency of 12 share factors. This superior efficiency was vital on the 1% degree throughout all a long time studied.
