India VIX

Sun, 21 Jun 2026 00:00:00 +0000

India VIX is the volatility index computed and disseminated by the National Stock Exchange , indicating the market’s expected volatility of the Nifty 50 over the next 30 calendar days, expressed as an annualised percentage and derived from the order book of Nifty 50 index options. NSE computes it using the CBOE VIX methodology and uses the “VIX” mark under licence from the Chicago Board Options Exchange. It is widely called the market’s fear gauge, because it climbs when traders expect turbulence and falls when they expect calm.

Max pain theory

Sun, 21 Jun 2026 00:00:00 +0000

Max pain theory holds that the price of an underlying tends to gravitate, at options expiry, toward the strike at which the total payout to all option buyers, calls and puts together, is the smallest. That strike is the max-pain strike. Stated from the other side, it is the price at which option writers, mostly dealers and market makers, retain the maximum premium, because the largest number of contracts across both calls and puts expire worthless there. The level is computed from the open interest reported on the National Stock Exchange option chain.

Nifty weekly expiry on Zerodha

Sun, 21 Jun 2026 00:00:00 +0000

Nifty 50 weekly options are the National Stock Exchange surviving weekly benchmark, the single weekly index contract the NSE is permitted to run under the Securities and Exchange Board of India one-weekly-per-exchange rule of November 2024. They are options on the Nifty 50 , the NSE 50-stock benchmark, expiring every Tuesday since 1 September 2025, cash-settled, and the most actively traded index option in India, listed on Zerodha in the NSE F&O segment on Kite .

Put-call ratio

Sun, 21 Jun 2026 00:00:00 +0000

The put-call ratio, abbreviated PCR, is an options-sentiment gauge that divides put activity by call activity in an underlying, computed from the option chain data published by the National Stock Exchange . A reading above 1 means more put activity than call activity, conventionally read as bearish positioning or heavy hedging; a reading below 1 means call activity dominates, read as bullish positioning. It is one of the most widely watched single numbers in Indian derivatives.

Weekly versus monthly expiry

Sun, 21 Jun 2026 00:00:00 +0000

Weekly and monthly expiry are the two tenors in which Indian exchange-traded options trade, distinguished by how often a contract expires and, since the 2024 to 2025 reforms, by how few instruments carry a weekly. After the Securities and Exchange Board of India restricted weekly options to one index per exchange in November 2024, only the Nifty 50 on the National Stock Exchange and the Sensex on the Bombay Stock Exchange have a weekly contract, while every single-stock option trades in a monthly tenor only.

NIFTY 10-year G-Sec Index

Tue, 19 May 2026 00:00:00 +0000

The NIFTY 10-year G-Sec Index tracks the benchmark 10-year Indian Government Security yield, serving as the principal long-tenor debt index for benchmarking gilt funds and dynamic-bond mutual funds. The index is constructed by NSE Indices (the index-construction arm of the National Stock Exchange) and is referenced widely by debt-fund managers, asset allocators, and macro-economic analysts.

For Indian retail investors, the 10-year G-Sec yield is the single most-watched indicator of Indian interest-rate conditions. The yield reflects:

NIFTY 5-year G-Sec Index

Tue, 19 May 2026 00:00:00 +0000

The NIFTY 5-year G-Sec Index tracks the benchmark 5-year Indian Government Security yield, serving as the mid-tenor debt index for benchmarking medium-duration gilt funds , banking-and-PSU debt funds, and certain dynamic-bond mutual funds. The index is constructed by NSE Indices and complements the longer-tenor NIFTY 10-year G-Sec .

For mid-duration debt-fund analysis, the 5-year G-Sec yield is the natural reference point. Its behaviour during yield-curve movements (steepening, flattening) provides insight into:

Short-medium policy-rate expectations.
Yield-curve shape vs the 10-year.
Inflation expectations over the medium term.

The index references the benchmark 5-year G-Sec (typically the most recently-issued 5-year paper or the most-traded 5-year security).

Weekly expiry contraction (November 2024)

Mon, 18 May 2026 00:00:00 +0000

The weekly expiry contraction of November 2024 collapsed the Indian weekly options expiry calendar from five distinct weeklies across two exchanges down to two. The change was one of the six measures in the SEBI F&O entry barrier rules 2024 framework dated 1 October 2024 and became operative from 20 November 2024 with the cutover handled by NSE and BSE through staged delistings of the affected contracts.

Before November 2024, Indian retail option traders had access to five weekly expiries across the trading week: Tuesday for Nifty Financial Services, Wednesday for Nifty Midcap Select and BSE Bankex, Thursday for Bank Nifty and Nifty 50 , and Friday for Sensex . The five expiries collectively dominated retail F&O turnover, with weekly contracts contributing approximately 70 to 80 per cent of total index options volume on most trading days in 2023 and the first three quarters of 2024. The variety enabled retail traders to deploy strategies that operated daily on a different weekly contract, with the proximity to expiry generating the high theta-decay and gamma-risk profile that retail option sellers and short-dated buyers respectively were seeking.

NIFTY 50

Sat, 16 May 2026 00:00:00 +0000

The NIFTY 50 is the principal large-cap equity benchmark index for the Indian equity market, computed and disseminated by NSE Indices Limited (formerly India Index Services & Products Limited or IISL), a wholly-owned subsidiary of the National Stock Exchange of India. The index tracks the weighted performance of 50 of the largest and most liquid Indian stocks listed on the NSE, selected from the broader NIFTY 100 universe through a methodology combining market-capitalisation and liquidity filters, and is rebalanced semi-annually in March and September. Alongside the Sensex of the Bombay Stock Exchange , the NIFTY 50 is one of the two principal equity benchmarks for the Indian market and is the more widely referenced index for derivative trading, exchange-traded funds, index funds, and mutual-fund benchmarking under the SEBI scheme rationalisation circular 2017 framework.
