Risk management Wed, 22 Apr 2026 09:00:00 GMT https://greeksgyan.bulansarkar.com/greeks/delta https://greeksgyan.bulansarkar.com/greeks/delta Delta measures how much an option's price is expected to change when the underlying moves by ₹1 — and doubles as a rough probability of the option finishing in-the-money. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/greeks/gamma https://greeksgyan.bulansarkar.com/greeks/gamma Gamma measures how fast Delta changes when the underlying moves — it is the acceleration behind an option's directional exposure, and it peaks for at-the-money options close to expiry. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/greeks/theta https://greeksgyan.bulansarkar.com/greeks/theta Theta measures how much value an option loses each day purely from the passage of time — the daily 'rent' an option buyer pays and an option seller collects. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/greeks/vega https://greeksgyan.bulansarkar.com/greeks/vega Vega measures how much an option's price changes when implied volatility moves by one percentage point — it is your exposure to the market's expectation of future movement, not to the movement itself. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/greeks/rho https://greeksgyan.bulansarkar.com/greeks/rho Rho measures how much an option's price changes when interest rates move by one percentage point — the least influential Greek for short-dated Indian options, but meaningful for long-dated positions. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/greeks/vanna https://greeksgyan.bulansarkar.com/greeks/vanna Vanna measures how an option's Delta shifts when implied volatility changes — equivalently, how Vega shifts when the underlying moves — a cross-Greek that matters most for skew-sensitive and Delta-hedged positions. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/greeks/charm https://greeksgyan.bulansarkar.com/greeks/charm Charm measures how much an option's Delta changes as one day passes — the 'Delta decay' that quietly re-shapes your directional exposure over time, especially near expiry. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/greeks/vomma https://greeksgyan.bulansarkar.com/greeks/vomma Vomma measures how much an option's Vega changes when implied volatility moves — the convexity of your volatility exposure, which makes long-Vega positions gain Vega as volatility rises. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/greeks/color https://greeksgyan.bulansarkar.com/greeks/color Color measures how much an option's Gamma changes as one day passes — the 'Gamma decay' that reshapes how fast your Delta will move, and it turns explosive for at-the-money options in the final days before a Nifty weekly expiry. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/greeks/speed https://greeksgyan.bulansarkar.com/greeks/speed Speed measures how much an option's Gamma changes when the underlying moves by ₹1 — the third derivative of price with respect to spot, which tells you how quickly your acceleration (Gamma) itself shifts as Nifty travels. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/greeks/ultima https://greeksgyan.bulansarkar.com/greeks/ultima Ultima measures how much an option's Vomma changes when implied volatility moves — the third-order volatility Greek that captures the curvature of volatility convexity itself, mattering most for out-of-the-money wings in violent volatility regimes. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/greeks/lambda https://greeksgyan.bulansarkar.com/greeks/lambda Lambda (also called Omega or elasticity) measures the percentage change in an option's price for a 1% change in the underlying — it is the true leverage of an option, telling you how many times harder your money works than buying the index outright. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/greeks/zomma https://greeksgyan.bulansarkar.com/greeks/zomma Zomma measures how much an option's Gamma changes when implied volatility moves — it tells you whether your directional acceleration will be sharper or flatter after India VIX shifts, and matters most to Gamma-hedged books in volatile markets. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/greeks/veta https://greeksgyan.bulansarkar.com/greeks/veta Veta measures how much an option's Vega decays as one day passes — it tells you how quickly your volatility exposure fades over time, which is why long-dated positions carry volatility risk that weeklies simply do not. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/interactions/delta-vs-gamma https://greeksgyan.bulansarkar.com/interactions/delta-vs-gamma Delta is your directional speed and Gamma is the acceleration that changes it — Delta tells you how much you make per point now, Gamma tells you how fast that per-point exposure grows as Nifty moves. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/interactions/theta-vs-vega https://greeksgyan.bulansarkar.com/interactions/theta-vs-vega Theta is what an option loses to the passage of time each day; Vega is what it gains or loses when the market re-prices expected volatility — two separate drains and lifts on premium that often fight each other around Indian event catalysts. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/interactions/delta-vs-theta https://greeksgyan.bulansarkar.com/interactions/delta-vs-theta Delta is the reward you earn when Nifty moves your way; Theta is the toll you pay every day while you wait — every directional option trade is a race between the move you need and the decay charging against you. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/interactions/gamma-vs-theta https://greeksgyan.bulansarkar.com/interactions/gamma-vs-theta Gamma and Theta are the two sides of the same coin: you cannot own favourable curvature (long Gamma) without paying daily decay (Theta), and you cannot collect decay without carrying accelerating move-risk — this is the single most important trade-off in options. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/interactions/vanna-vs-vega https://greeksgyan.bulansarkar.com/interactions/vanna-vs-vega Vega is how much your option value moves when implied volatility changes; Vanna is how your directional exposure (Delta) shifts when that same volatility moves — Vega is the volatility bet, Vanna is the hidden directional side-effect of it.

Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/interactions/greeks-during-expiry https://greeksgyan.bulansarkar.com/interactions/greeks-during-expiry As expiry approaches, Gamma and Theta explode at the at-the-money strike, Charm pulls Deltas toward 1 or 0, and Vega fades to nothing — expiry day is when the Greeks stop being gentle sensitivities and become violent, fast-moving forces.

Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/strategies/long-call https://greeksgyan.bulansarkar.com/strategies/long-call A long call is positive Delta, positive Gamma, positive Vega and negative Theta — you are long direction, long movement and long volatility, and you pay daily time decay for all of it. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/strategies/long-put https://greeksgyan.bulansarkar.com/strategies/long-put A long put is negative Delta, positive Gamma, positive Vega and negative Theta — you are short direction but long movement and long volatility, paying daily time decay for downside protection or a bearish bet. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/strategies/covered-call https://greeksgyan.bulansarkar.com/strategies/covered-call A covered call — long stock or futures plus a short call — is net positive but reduced Delta, negative Gamma, positive Theta and negative Vega, converting an outright long into an income position that caps upside and collects time decay. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/strategies/covered-put https://greeksgyan.bulansarkar.com/strategies/covered-put A covered put — short stock or futures plus a short put — is net negative but reduced Delta, negative Gamma, positive Theta and negative Vega, an income trade on a bearish-to-neutral view that caps the downside profit and collects time decay.

Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/strategies/bear-spread https://greeksgyan.bulansarkar.com/strategies/bear-spread A bear put spread — long a higher put, short a lower put — is net negative Delta with small and shifting Gamma, Theta and Vega, a defined-risk bearish trade whose secondary Greeks are largely neutralised by the short leg. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/strategies/straddle https://greeksgyan.bulansarkar.com/strategies/straddle A long straddle — buy the ATM call and ATM put together — is near-zero Delta, strongly positive Gamma, strongly positive Vega and heavily negative Theta, a pure bet on a big move and rising volatility that pays double time decay to hold. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/strategies/strangle https://greeksgyan.bulansarkar.com/strategies/strangle A short strangle is short Gamma, short Vega and positive Theta — you sell an OTM call and an OTM put to collect decay while betting Nifty stays range-bound; a long strangle flips every sign. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/strategies/iron-condor https://greeksgyan.bulansarkar.com/strategies/iron-condor An Iron Condor is short Gamma, short Vega and positive Theta with defined risk — it sells an OTM call spread and an OTM put spread to harvest decay while Nifty stays range-bound, with the long wings capping the loss. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/strategies/iron-butterfly https://greeksgyan.bulansarkar.com/strategies/iron-butterfly An Iron Butterfly is short Gamma, short Vega and strongly positive Theta with defined risk — it sells an at-the-money straddle and buys OTM wings, collecting a fat credit that pays off only if Nifty pins near the centre strike. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/strategies/calendar-spread https://greeksgyan.bulansarkar.com/strategies/calendar-spread A calendar spread is long Vega and positive Theta at the same time — you sell a near-term option and buy a longer-dated option at the same strike, profiting from the faster decay of the front leg while staying long volatility. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/strategies/ratio-spread https://greeksgyan.bulansarkar.com/strategies/ratio-spread A ratio spread sells more options than it buys, so its Greeks flip beyond the short strikes — typically positive Theta and net short Gamma and short Vega, with an open tail of directional risk from the extra naked short. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/strategies/butterfly https://greeksgyan.bulansarkar.com/strategies/butterfly A long butterfly is positive Theta near the body and net short Gamma and short Vega there — a low-cost, defined-risk bet that Nifty pins the centre strike, built by buying the wings and selling twice the body. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/strategies/broken-wing-butterfly https://greeksgyan.bulansarkar.com/strategies/broken-wing-butterfly A broken wing butterfly is a skewed butterfly — often entered for a credit — that keeps the positive Theta and short Vega of a normal butterfly while shifting the risk entirely to one side by widening the far wing.

Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/nifty/finnifty-greeks https://greeksgyan.bulansarkar.com/nifty/finnifty-greeks FinNifty is the financial-services index — broader than Bank Nifty but still sector-focused — so its Greeks sit between Nifty and Bank Nifty in intensity, with Vega and Gamma driven by RBI policy, banks, NBFCs and insurers rather than the whole market. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/nifty/weekly-expiry-greeks https://greeksgyan.bulansarkar.com/nifty/weekly-expiry-greeks Weekly options have far faster Theta and much higher expiry-week Gamma than monthly contracts, so their Greeks are compressed into a few days — time decay is brutal for buyers and Gamma risk is severe for sellers.

Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/nifty/0dte-greeks https://greeksgyan.bulansarkar.com/nifty/0dte-greeks On expiry day (0DTE) Gamma and Theta go to extremes — Delta can flip almost instantly on a small move while time value evaporates by the hour — making expiry-day options the fastest and most dangerous Greeks in the market. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/nifty/intraday-greeks https://greeksgyan.bulansarkar.com/nifty/intraday-greeks For intraday trades Delta and Gamma dominate your P&L while Theta and Vega barely register over a few hours — so intraday option trading is essentially a directional Delta bet with Gamma controlling how fast that bet accelerates. Tue, 07 Jul 2026 09:39:32 GMT https://greeksgyan.bulansarkar.com/nifty/overnight-greeks https://greeksgyan.bulansarkar.com/nifty/overnight-greeks Holding options overnight adds gap risk and event/Vega exposure to your Delta and Gamma — the market can jump on overnight global cues before you can react, and at least one full day of Theta is charged whether or not the index moves.
