Markets don't move in a straight line up and when overbought, they will revert to the mean. Given the economic circumstances and the Fed withdrawing liquidity, I think that time is now.
My primary Elliott Wave count has a pullback to at least 2900 for an ABC correction. However if we get an impulse to 2700, then I'd expect a small bounce and another drop to ~2580.
I'm a long term buyer at either of these levels, but short until then.
