Dear friend, I have major math statistic. I was making money writing open forecasting models. I’m trading looong time and now it’s my profession.
Let me tell you secret. These models forecast only work for nearest future. Regression, correlation, cluster, factor, functional analysis if it tells you
something. You predict 3200 looking for trend, OMG. It would happened and may not sooner or later. You predict we recover, sure we do. Only question when. You know what you are missing, you did not provide evidence why it will happened. Instead you pointed I do not get it.
Open model with many impacting factors for long run is unpredictable.
