Well, v briefly, I don't see much about ANY strategy to say its no-brainer". I don't believe in the long term upward bias either (have a look at the last ten years).
Market hits lows,bounces back, repeats so traders keep expecting the same. Until at some point it doesn't and then all hell breaks loose. Would be good if today's is that day, but you would probably need some news to come out to trigger it.
