NSE & BSE Indices Futures and Options Open Interest Volume Analysis for 9/10/2025
Table of Contents
On 9th October 2025, the combined futures and options setup told a nuanced story of selective optimism and sector rotation, as highlighted by Open Interest Volume Analysis. Nifty’s combined futures open interest dipped by 1%, reflecting broad short covering in the face of mild price gains, suggesting that traders are booking out of Friday positions rather than chasing a breakout.
However, the November futures contract showed fresh long interest—signaling that market participants remain confident about the next leg up but are shifting their bets further out on the calendar. Bank Nifty, on the other hand, reversed trend with combined futures OI climbing 1.3%, driven by fresh long accumulation in both October and November series, which hints at a strong undercurrent of demand in financials. Finnifty was the standout, with a sharp 13% surge in OI across all contracts and aggressive long builds in both October and November, confirming that financial sector appetite remains robust.
In contrast, Midcap Nifty displayed sectoral divergence: short covering in October but fresh long additions in November, a sign of participants cherry-picking midcap exposure for the next week. Sensex futures showed aggressive short covering—down nearly 11% OI—even as spot prices rose, paralleling the bullish bias. Today’s Open Interest Volume Analysis reveals a market warming up to new positions in select pockets while keeping risk balanced in others.

Conclusion: What the NSE & BSE Indices Futures and Options Open Interest Volume Analysis Tells Us
The derivatives snapshot for 9th October 2025 paints an interesting pre-weekend setup. Nifty and Sensex are dominated by short covering, highlighting that profit booking and rollover unwinding are still in play for index heavyweights. Yet the distinct fresh long buildup in Bank Nifty, Finnifty, and Midcap Nifty (especially in November contracts) shows the market’s confidence is re-emerging within financials and select midcaps.
Options data backs this up: rising PCR in both weekly and monthly series for Bank Nifty, Finnifty, and midcap contracts points to strengthening support, even as call writers continue to cap upside close to resistance. Overall, the Open Interest Volume Analysis signals that while broad index moves remain cautious, sector-led bullishness is quietly gathering force and may drive the next directional move if global cues stay friendly and domestic triggers align post-expiry.
