NSE & BSE Indices Futures and Options Open Interest Volume Analysis for 8/10/2025
Table of Contents
On 8th October 2025, the combined futures and options data reflected a cautious mood in the market, as Open Interest Volume Analysis showed a predominance of short covering with some fresh short additions, signaling a mixed and tactical positioning ahead of important expiry dates. Nifty’s combined futures open interest slipped 1.4%, driven by long covering in near-term October contracts, while November showed fresh short interest creeping in, hinting at a market bracing for near-term volatility.
Bank Nifty echoed this theme, seeing a 3.5% combined OI decline, consistent with bulls unwinding some positions, but November contracts gained fresh longs, revealing pockets of confidence in the banking sector’s medium-term outlook. In contrast, Finnifty and Midcap Nifty both saw combined futures open interest rise, dominated by short additions across series, reflecting traders’ cautious stance in broader market segments.
Sensex futures showed a 3.4% rise in open interest, primarily due to fresh short accumulation, underlining a defensive stance among institutions. Today’s Open Interest Volume Analysis points to a market in consolidation, with participants preparing for moves in either direction as expiry pressures mount.

Conclusion: What the NSE & BSE Indices Futures and Options Open Interest Volume Analysis Tells Us
The derivatives positioning on 8th October 2025 tells a nuanced story of balance and anticipation. The combined data shows that while short covering dominated near-term contracts in some indices, fresh short positioning in November and across broader futures signals that traders remain cautious about broader sustainability of gains.
The divergence between fresh longs in Bank Nifty’s November contracts and continued short buildup in Finnifty and Midcap Nifty underscores the selective nature of the market’s optimism. Options data with decreasing PCR reflects traders’ guarded risk appetite and willingness to hedge rallies at resistance zones. Overall, the Open Interest Volume Analysis suggests the market is at a crossroads—primed for a meaningful move but presently marked by consolidation and hedging as participants wait for decisive triggers in the week ahead.
