I seem to remember Otar describing his market timing philosophy. It's been a few years since I read it, but I remember it was something like reducing the equities from say 50% to 30%. He was looking at the S&P500 PE. What I'm remembering is if both the 10week and 52week moving average are still going up, stay the course.
I've looked at the long range chart. What looks crystal clear in the historical, doesn't look so clear when you look forward.
