Which Trend is Your Friend?
The Classic 12-Month Simple Moving Average? No!
It would be more than shocking if exactly one year of equal-weighted returns turned out to be the optimum way to measure trends indicative of future performance. But it was simply an experimental choice made by an early academic momentum researcher later copied by others. That choice betrays that they had no knowledge of signal processing theory (that digs signals out of the noise and makes WIFI, digital TV, and remotely controlled rovers on Mars possible).
Can Shorter Trends Respond Faster and Better? No!
They can respond faster, but not better. Sharp drops often snap back, leaving nervous sellers with whipsaw losses when they buy back into the market at a higher price. The common wisdom of “buy the dips” suggests doing the opposite for just this reason. It takes time to safely confirm a trend. See Example Analysis Here
Are Optimum Trend Settings Stable Over Decades? No!
The trend character of the market sometimes changes in reaction to political, economic, and world events. Our Forward-Walk Progressive-Tuning technology automatically adapts the trend measurement settings in response to the market and character of the candidate funds. This Tuning Profile for an ordinary SPDR sector rotation strategy shows how it adapts.
