What is India VIX

What is India VIX? Complete Guide with Daily, Weekly & Monthly Range Calculation

India VIX, also known as the Volatility Index, is one of the most important indicators used by traders and investors to understand the expected volatility of the Indian stock market. It is often called the "Fear Gauge" because it reflects the market's expectation of future volatility over the next 30 calendar days.

Unlike the Nifty 50 Index, which measures the direction of the market, India VIX measures the expected magnitude of price movement, regardless of whether the market moves up or down.

What Does India VIX Measure?

India VIX is calculated using the bid and ask prices of Nifty Option contracts. It estimates the annualized volatility expected by option traders over the next 30 days.

In simple words:

• High India VIX = High uncertainty and larger market swings expected.
• Low India VIX = Stable market and smaller price movements expected.

---

How India VIX Works

India VIX represents an annualized volatility percentage. For example:

• India VIX = 13 means the market expects approximately 13% annual volatility.
• This does NOT mean the market will fall by 13%.
• It simply represents the expected movement (up or down).

How is India VIX Calculated?

The National Stock Exchange (NSE) calculates India VIX using the Black-Scholes option pricing methodology and real-time prices of Nifty Options.

The simplified expected movement formula is:

Expected Move =
Nifty × (India VIX ÷ 100) × √(Time ÷ 365)

Where:

• Nifty = Current Nifty Index
• India VIX = Current VIX Value
• Time = Number of calendar days

Example Calculation

Assume:

• Nifty = 24,050
• India VIX = 13

Daily Expected Range

Expected Move

= 24,050 × (13/100) × √(1/365)

≈ 163 Points

Current Nifty	Daily Expected Move	Lower Range	Upper Range
24,050	±163	23,887	24,213

This means the options market expects Nifty to remain within this range approximately 68% of the time during a normal trading day.

---

Weekly Expected Range (7 Days)

Expected Move

= 24,050 × (13/100) × √(7/365)

≈ 433 Points

Current Nifty	Weekly Move	Lower Range	Upper Range
24,050	±433	23,617	24,483

---

Monthly Expected Range (30 Days)

Expected Move

= 24,050 × (13/100) × √(30/365)

Shortcut Formula Used by Professional Traders

≈164 Points

Weekly Range

Daily Move × √7

164 × 2.646

≈434 Points

Monthly Range

Daily Move × √30

164 × 5.477
