As a basis for PC%, ocroft has stated in several posts including 40389 that using MACD (24,52,9) as an entry point
when the stocks monthly Macd does a crossover, you can anticipate that the price will rise above its moving average. I use 20/40 EMA
leads me to believe this methodology may tell us more. If for example we trend the 2 MACD averages, we could look for a pattern, whether in the R-Squared value or by High/low points between crossover points to determine what PC% could be. I've also considered (very early in the process) Black-Litterman allocation prediction as a basis.
Still though, a lot of thinking and testing to do. As a caveat, the danger becomes too much tinkering or, as we used to say in the airplane world, chasing the needle can lead to undesirable effects.
