These are my thoughts as well -- not enough data. I've had really good luck in 2016 (bought into natural gas during the price-of-oil collapse; bought into safe stocks being panic-sold after Brexit), but I almost feel like I'm living on borrowed time.

I'm planning on writing a book on my strategies (or maybe seeking backing for an actively-managed mutual fund?), but only if I can enjoy 10 years and one full market cycle of success...
