When I queried my wife, friends and acquaintances about India VIX, I was mentally building framework for this article. Before going to India VIX, let us first briefly understand about volatility Index. Volatility is often referred as the changes in prices and in finance often termed as risk. Volatility index basically measures market expectation of short term volatility. In other words, volatility index is a good indicator of the perception of investors on how volatile market would be in short term. During period of market volatility, market may move steeply up or down and as a result volatility Index (also referred as VIX Index) tends to rise. VIX, started by Chicago Board Options Exchange (CBOE), is a global trademark of volatility index. VIX measures implied volatility of S&P 500 index options.
Coming back to India VIX, it is a volatility Index introduced by National Stock Exchange (NSE) on the Nifty 50 index option prices. India VIX Index, calculated by NSE, shows expected market volatility over the next 30 calendar days just like original VIX. Higher the India VIX values, higher the expected volatility in market and vice versa. Investors or market participants can gather more information on VIX from NSE website.
Nifty 50 Index is an absolute number and signifies directional movement of the market. On the other hand, India VIX is a percentage value which indicates expected volatility in short term and how expected volatility is changing from time to time.
As we see in the chart, Nifty and India VIX Index has negative correlation. Correlation between Nifty and India VIX (both over 4 yrs and 1 year) is around -0.833, which makes it a good tool to hedge positions in Nifty. However, investors will have to wait for futures and options in India VIX to be started by NSE.
We also observe in the chart that India VIX Index started inching towards 17 and above from low of 13.3 when market started falling this year (Jan’13 onwards). The India VIX Index is more useful for market participants in derivatives markets (buying selling of futures and options contract).
