As a technique, shopping for the market on days when it eclipsed its 50-day transferring common generated each day common returns between 0.11% and 0.18% throughout the six many years surveyed, with the excessive mark reached within the Eighties. Shopping for the market on days when it fell under the transferring common resulted in common each day returns between -0.14% and -0.28, with the Eighties additionally accounting for the most important losses.

To provide a way of the magnitudes right here: If an investor had been to purchase day-after-day the market was over its 50-day transferring common within the Nineteen Sixties and brief day-after-day that it was under, this could yield a mean yearly return simply round 22%, whereas the S&P 500 generated a geometrical common return of 10% over the last decade. This implies an extra efficiency of 12 proportion factors. This outperformance was important on the 1% degree throughout all many years studied.
