The Indian stock market, like its global counterparts, rises due to optimism amongst investors and, falls down due to fear, and thus presents a spectrum of opportunities in its constant fluctuations. But how do you, as a trader, gauge the current sentiment and navigate this ever-shifting landscape? 

India VIX Volatility Index (India VIX), is a crucial tool that helps you do just that by giving you a score of the market’s underlying anxiety or confidence.

What is the India VIX?

India VIX, launched in 2003 by the National Stock Exchange (NSE), is a volatility index. Unlike traditional indices that track stock prices, the India VIX reflects the market’s expectation of volatility in the Nifty 50 index, a benchmark for the Indian stock market, over the next 30 calendar days.

Think of it as a mood meter. A high India VIX reading suggests investors are anxious, anticipating significant price swings in the Nifty 50. Conversely, a low India VIX indicates a calmer market environment with expectations of smaller price movements.

How is India VIX Calculated?

The India VIX calculation factors in the prices of Nifty 50 option contracts across various strike prices and expiry dates. Essentially, the option prices themselves embed market expectations of future volatility. By crunching these numbers, the India VIX delivers a single numerical value that captures the market’s overall volatility sentiment.

VIX uses call and put options prices for different strike prices for current and next month expiry with at least 3 days to expiry, so the current VIX is based on April and May expiries. The value of VIX will tell you, how much movement in Nifty 50 is expected over next 30 days.

The VIX number you can see on the charts on NSE is an annualised number which on the closing of 9th April 2024 stands at 11.36. But what if you need to find out what it will be for this month?

To calculate this, we need to divide the above number by the square root of 12. Why? Because time is taken as 360 (proxy for 365 days of a year) and then dividing it by the number of days for which we are computing it, which in the case of monthly is 30.

So,

360 / 30 = 12

Square root of 12 = 3.464

Hence, monthly volatility = 11.36 / 3.464 = ~3.28 and this number is in percent figure, so 3.28%

Nifty closed at 22642 on 9th April, so expectation of closing in 30 days is between 3.28% of the current spot price viz between the range of 21900 and 23384.

Understanding the Importance of India VIX

India VIX provides investors and traders with the following insights that help them in their trading and investing journey

Risk Management

A high India VIX reading serves as a cautionary flag. It highlights a market environment with potentially large price swings, prompting investors to potentially adjust their strategies and manage risk exposure. This might involve reducing portfolio leverage, implementing stop-loss orders, or hedging positions through options strategies.

Investment Decisions  

India VIX can inform investment decisions. When the VIX is low, it suggests a potentially opportune time for long-term investments, as the market anticipates a period of relative stability. Conversely, a high VIX might signal a time for caution or even short-term trading strategies to capitalize on potential market swings.

Trading Strategies

Savvy traders can utilize the India VIX to devise options-based strategies. For instance, during periods of high VIX, options selling (writing calls or puts) can generate income premiums by capitalizing on the market’s fear.

Decoding the India VIX Movements

The India VIX is a dynamic indicator, constantly fluctuating in response to various market events. Some of the events that have historically shown an increased VIX are as follows:

Economic Data Releases

Important economic data releases, such as GDP growth figures or inflation rates, can significantly impact the India VIX. Unexpected economic news can trigger volatility concerns, pushing the VIX higher.

Geopolitical Events

Global or domestic political tensions can inject uncertainty into the market, leading to a rise in the India VIX.

Corporate Earnings

Earnings announcements from major companies can influence the VIX. Disappointing earnings might raise concerns about future profitability and increase volatility expectations.

Interest Rate Decisions  

Changes in interest rates by the Reserve Bank of India (RBI) can impact market sentiment. Rising interest rates can potentially lead to higher VIX readings.

Limitations of India VIX

While a valuable tool, the India VIX has its limitations:

Short-Term Focus

The India VIX only reflects volatility expectations for the next 30 days. It doesn’t necessarily predict long-term market trends.

Limited Scope

The India VIX solely focuses on the Nifty 50 index. It doesn’t provide insights into the volatility of broader market segments or individual stocks.

Conclusion

By understanding India VIX you can gain a valuable perspective on the market’s underlying mood. This knowledge empowers you to make informed investment decisions, manage risk effectively, and potentially navigate short term market volatility with greater confidence.

Remember, the India VIX is just one piece of the puzzle. Always consider it alongside other market indicators and conduct your own research before making investment decisions.
