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 the 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 or normal range, then it
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 in bounding range or upward trending, the
VIX does not work well. Under this circumstance, you better 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 the
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 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.
