Volatility is still low, before disaster come we may see a couple of weeks of side-way action. Even if we have 2-5% decline, most likely we will have a bounce up. If it happens and Volatility on the S&P 500 goes up (14-ay ATR moves above 1.3%) then we may talk aout a coming disaster.
If we do not se increase in voltility then we cannot expect a disaster. Low volatility = calm investors.
