The CBOE Volatility Index (VIX) is a
sentiment indicator that passively
reflects the stock market movements. Therefore, the VIX is not used to predict
the direction of the market. Instead, it should be applied to identify
sentiment extremes and help investors and traders to detect optimal trading
opportunities.
Dramatic and unexpected stock market
deterioration usually causes the extravagant spikes in the VIX reading, as
panic dominates and penetrates the investor’s mind. If the spikes go beyond a specific
level (measured by the moving average of VIX), then this indicates that a
gigantic bearish sentiment can spur a market recovery.
Technically speaking, when the market
drops, the VIX can better detect the reversals. However, if the market is in
bounding range or upward trending, the VIX does not work well. Under this
circumstance, it is best to combine the VIX with other technical indicators
such as RSI, ISEE, TRIN, SMFI, etc.
On the other hand, a
sustainable and robust stock market gain yields a gradual downward and
comparatively depressed level for this index. Undue bullishness makes it
challenging to foretell if the market is going to continue its trending path. Therefore,
the VIX can better detect the bottom than the top. It would be wise to apply
the VIX, accompanied by other technical indicators, to identify imminent market
reversals.
Occasionally, an unforeseen debacle
might arouse the swell in VIX reading as well. For example, many investors and
traders around the world still remember the outrageous flash crash which
occurred on 5/6/2010. This created a broad and inverse impression of the stock
market.
As a matter of fact, the market
started its correction from 4/26/2010 amidst the sovereign debt concern. However,
the “fat-finger” incident just amplified the market moving magnitude. Even if
the market recouped most of its losses at the end of day, the S&P index
dipped to an intraday low of 1,065 and managed to close at 1,128. The S&P
500 index dropped 106 points in total from 4/26/2010 to 5/7/2010. Within the
next three days, the S&P 500 snapped up half of the loss. Then the market
resumed the downtrend after that.
On 5/25/2010, the market broke its
intraday low on 5/6/2010 and reached the low of 1,040. On 5/27/2010, the VIX
had a bigger hike than that of the infamous flash crash day. Since the Euro
dropped significantly and entered the dangerous zone, the S&P lost 43
points that day. After the big rise of the VIX, the fear was relieved.
Therefore, the market bottomed out and made a reversal.
