How VIX Acts as a Coincident Indicator


The Volatility Index (VIX) is also recognized as a coincident indicator.  As a matter of fact, VIX can be adopted as a trend-confirming barometer as well, since it is trending against the stock market. 

In the range bound stock market, the VIX is able to uncover sentiment excess, which can be employed to prophesy the market reversals.

In the current forceful bull market, the VIX stayed in the depressed level most of the time. The spikes occurred once in a while, but the VIX recovered immediately. There was no apparent uptrend or downtrend tendency.  In January 2013, the range for the VIX shifted to lower levels for both upper bound and lower bound.

The above chart discovers that the VIX index corresponds inversely to $SPX when market extremes occur. It reveals that in the past year, the VIX index ranged between 12 and 22.  It had several spikes and troughs.  The VIX stayed between 12 and 16 most of time due to rampant market momentum.

The VIX spiked to 22 on 12/28/2012, corresponding to the fact that the market was disappointed with the fiscal deal negotiation. The S&P surrendered 15 points that day. The market exhibited fear and anxiety.  The VIX is often referred to as the “fear index” by its very nature.  Fortunately, the struggling and battling fiscal deficit deal opponents reached an agreement.  The market had risen steadily.  The VIX reading moved to a lower level since then.
