Live FIN NIFTY option chain with full Greeks, max pain, PCR, and dominant OI strikes for India's financial services index. Tuesday weekly expiry.
FIN NIFTY (NIFTY Financial Services) is NSE's broader financials index, covering banks plus NBFCs, asset managers, and insurance companies. It's a popular trading vehicle because its Tuesday weekly expiry offers an alternative to NIFTY's Thursday and BANK NIFTY's Wednesday — letting traders position around different parts of the week's news cycle.
Strota's FIN NIFTY option chain shows live strikes, computed Greeks (Delta, Gamma, Theta, Vega), max pain recomputed from live OI, the 5-day PCR trend, and the highest call and put OI strikes that frequently anchor the weekly expiry.
Underlying basket: roughly 20 stocks spanning banks (HDFC Bank, ICICI, Axis, Kotak, SBI), NBFCs (Bajaj Finance, Cholamandalam, Shriram Finance, Muthoot, Bajaj Finserv), asset managers (HDFC AMC, Nippon AMC), insurance (HDFC Life, SBI Life, ICICI Pru), and brokerages (Angel One, Motilal Oswal).
BANK NIFTY is just banks. FIN NIFTY is banks plus everything else financial — NBFCs, AMCs, insurance, brokerages. The two diverge frequently because non-bank financials respond to different drivers.
When credit growth is strong but RBI keeps rates steady, BANK NIFTY can underperform FIN NIFTY because NBFCs (which fund themselves wholesale) get squeezed less than banks (which pay savers nothing while loan rates compress).
When IPO activity is hot, asset managers and brokerages within FIN NIFTY rally hard while pure banks lag — another common FIN-vs-BANK divergence.
Knowing which index to trade for a given thesis is half the battle. The Strota sector flow page makes this comparison explicit.
FIN NIFTY weekly options expire every Tuesday. That's earlier in the trading week than NIFTY (Thursday) and BANK NIFTY (Wednesday), meaning Tuesday-expiry positioning gets unwound before the bigger expiries hit.
Practical implication: FIN NIFTY's max pain and PCR are most predictive Monday-Tuesday, less so Wednesday-Friday when the chain rebuilds for next week's expiry.
If you're trading FIN NIFTY directionally, Monday morning is often the highest-edge entry — you have 2 days of decay capture into Tuesday's settlement, and option pricing tends to be richest at the start of the new weekly cycle.
Same calculation as NIFTY or BANK NIFTY — the strike at which total open option intrinsic value is minimised on expiry.
What's slightly different about FIN NIFTY's max pain: the underlying basket is more diversified than BANK NIFTY's 12 stocks, so the gravity is somewhat weaker. FIN NIFTY tends to drift to max pain on Tuesday afternoon but not pin as tightly as BANK NIFTY does on Wednesday.
Strota recomputes max pain on every page refresh from live NSE OI, so the number you see is current.
Every Tuesday. Monthly contracts expire on the last Tuesday of each month.
Around 20 stocks covering banks (HDFC Bank, ICICI, Axis, Kotak, SBI), NBFCs (Bajaj Finance, Cholamandalam, Shriram), asset managers (HDFC AMC), insurance (HDFC Life, SBI Life, ICICI Pru), and brokerages (Angel One, Motilal Oswal). Weightings updated periodically by NSE Indices.
FIN NIFTY if your thesis is about broad Indian financials including NBFCs and insurance. BANK NIFTY if your thesis is purely about banking sector and rate-cycle dynamics. Their weekly expiry days are different (Tuesday vs Wednesday), so you can run both with non-overlapping time decay schedules.
Slightly less, because the underlying basket is more diversified. FIN NIFTY's typical implied volatility runs 10-20% below BANK NIFTY's. That means cheaper option premiums but also smaller intraday swings.
Less so. BANK NIFTY remains the highest-volume index option after NIFTY 50. FIN NIFTY weekly options are liquid at the at-the-money and near strikes, but spreads widen meaningfully 200-300 points away from spot.
