One thing the recent market weakness has accomplished is to turn consensus opinion firmly bearish. There is no doubt about it. Sentiment, as measured by the VIX, has made an extreme move on a long-term basis, and it may be another signal that this market has gone about as far as it can to the downside without some lift occurring first.

The VIX is simply a measure of fear, as volatility is a nice-sounding word for fear. When the consensus becomes this one-sided, the probabilities of a swing the other way and a reversion to a more median reading in the VIX away from the recent extreme, increases significantly.

In a normal world, most price movement is contained to about two standard deviations. The VIX has moved out beyond four standard deviations of the 200-day moving average. A four-standard-deviation move away from the 200-day moving average marks an extreme move that we have seen in only 11 previous situations. The market has shown a strong upside bias once a signal has been reached.

Many technicians have looked at this selloff and are predicting the start of a bear market. This may be the case, but it's just a guess, nothing more. The market is oversold, as measured by our 40-day SARSI indicator, the uptrend channel for this rally remains intact, the long-term trend for breadth remains intact and sentiment is at a rare bearish extreme. All the signs for a bullish reversal are there.

If this is the start of a bear market, you won't know until the rally plays out. The decline isn't the key, the rally is. We would watch for a weak countertrend type of move back toward the prior highs to start getting bearish, not now with every bullish reversal signal in the book flashing "buy."

If we go back and look at each occurrence of a four-standard-deviation move in the VIX, in most cases it was "the" low. This is cold comfort when the market is acting as heavy as it did today, but traders should keep this in mind.

The sentiment picture is about as bad as we have ever seen it. The selling has been brutal, but if we look at the longer-term charts for the major indices, surprisingly little damage has been done. The reason for this is that the distribution of stocks started in May. The market weakened internally starting in May, and this 10% correction has been the last-stage "blow-off" to the downside.

The possibility of this being the start of a bear market is present, but there simply isn't enough information to make that determination. The market will rally and that rally will give us the clues we need to decide if this is an old bull or a new bear.
