"In summary, it seems as if the market is slowing down, but the indicators are still overwhelmingly bullish, as the only sell signals right now are the put-call ratios and breadth. Thus, it is important to wait for $SPX and $VIX to confirm before attempting to take a strong bearish position."

SP chart is extended, overbought, as are many other indicators, but the bullish trend remains intact. Sell-off gives us a chance to see whether the underlying trend is still strong or not.

                           If VIX closes above 16, that would be a sell signal for stocks.
