volatility changes can warn of impending trend changes in price.
Option and futures premiums increase due to an increase in
volatility. There are two major Indices that track volatility.
The first is the VIX or Volatility Index. Developed in 1993, the
CBOE's volatility index is a measure of volatility of the US equity
market. The VIX is calculated by taking the weighted average of the
implied volatilities of eight OEX calls and puts with an average time to
maturity of 30 days. Most often it is considered a contrarian
indicator, where high reading are considered oversold territory and low
readings are overbought. Notice as well that volatility
measures often move inversely to the price trend of major indices.
Rising volatility often confirms expectation of declining markets and
corresponds with downward moving prices. Falling volatility often
accompanies rising markets and supports a bullish outlook in near
term. These are only indications but can be used to help build
supporting evidence of price trend. A confirming VIX reading
supports price trend indications present in the markets. A VIX
that is not confirming price trend may suggest that the price trend
is suspect.
The
second measure of volatility found in the market place is the CBOE Nasdaq Volatility Index. One
use in tracking volatility for option traders
is in recalculating option price projections based on projected changes in
volatility. Determining the current volatility and extrapolating
future possible values of volatility allows option traders to use
option pricing systems like the Black Schoels to calculate possible
price projections for an option given an expected
volatility.
A
declining volatility level over time suggest that bullish sentiment exists
in the markets for the longer term price trend. A rising volatility
level over time carries bearish sentiment. Tracking volatility
allows a glimpse of what traders feel are the possibilities of price trend
in the near term. Falling values in volatility suggest a bullish
bias. Rising volatility levels suggest a bearish bias.
