The key words are "expectation of volatility." It says nothing about the direction of said volatility. High VIX readings can be associated with both bullish and bearish conditions. As a measure of expected future volatility, the higher readings tell us that traders are anticipating an increase in market volatility, which is usually associated with a trend change.
The VIX by itself is not particularly useful. But combine the VIX with other chart analysis methods and the trader has a good idea of the direction of the volatility move i.e. it tells the trader about the direction of the trend change, or trend acceleration.
If I am long and an uptrend is developing then a high VIX reading is nothing to fear. If I am long and the market is showing some signs of end-of-trend behavior and the VIX gives a high reading, then I need to be fearful.

This takes us back to the recent VIX chart, which showed a dramatic decline is the VIX reading. What had the market been afraid of that drove the VIX to the previous highs? The upcoming FOMC meeting and the potential for an interest rate rise was the primary fear in the market. There was a high expectation of volatility and the consequent potential for a trend change or acceleration.
The, suddenly the VIX dropped. This gave a clear indication that the market did not expect a rise in interest rates. It expected the situation to remain unchanged. No need to volatility and mo need to anticipate a significant potential for trend change.
The VIX indicator gave traders the answer on what the Fed's move would be long before it became reality. The VIX, used properly, assists traders to anticipate the potential for significant trend change. Combined with other chart analysis methods it provides a significant trading edge, which is nothing to be fearful of.
