The SP500 CBOE volatility index began rising at 14:39 EST from 27.97 to 28.46 with SPX still gently rising on a generally rising SPX day. CBOE P/C was also relatively high all day. Today is four weeks from the lowest 2CS reading (5 day summation of daily VXO * P/C). Other market-based sentiment measures have put in their extremes in the past four weeks. My best guess is that the generic stock market is ready to fall.
