Yup,good question...I get dispersion,but do not get how this info posted puts $$$ in ones pocket...
I'm sincerely asking because there is a lot of fascinating studies and research to be done, but at the end of the day what matters is if it's actionable and consistent for making profits.
I haven't looked into the specifics posted in this thread and probably won't anytime soon, but it's also my experience that any kind of intermarket relationship is fleeting and inconsistent. And if something only works some of the time, I'll take a pass and rather narrow down my focus.
