Which Stocks Witnessed the Biggest Open Interest Moves This Week?
Every trading week, derivative positions tell a powerful story about market sentiment. The movement in open interest (OI) — the total number of outstanding derivative contracts — reveals where traders are building or unwinding positions. Let’s decode the latest weekly OI data and what it signals for Nifty, Bank Nifty, and major stock futures.
About the Weekly Open Interest Report
The Open Interest (OI) data is a key indicator for futures and options traders. A rise in OI with a price increase indicates fresh long positions, while a fall in OI along with a price drop signals long unwinding. On the other hand, rising OI amid price declines points to fresh shorts being added. This weekly report captures the biggest OI movers across stocks, helping traders identify trend shifts early.
Weekly OI Gain and Loss Summary
The following table lists the top stocks that saw significant changes in their open interest positions during the past week. It helps identify where institutional traders are increasing exposure and where they are booking profits or cutting losses.

Sectoral and Market Insights
Metals and banking stocks continued to attract fresh long build-up, with Hindalco leading the charge. Financial counters such as RBL Bank also saw aggressive accumulation, suggesting optimism about credit growth in the upcoming quarter. Conversely, large-cap auto and pharma names like Maruti and Dr. Reddy’s witnessed profit booking and short build-ups.
The rise in open interest in selective stocks despite broader index consolidation indicates rotational participation by traders. Metal and industrial names have started gaining attention, while IT and auto segments show signs of cooling off after extended rallies.
How Traders Can Use This Data
Tracking OI movements helps traders identify strong momentum pockets and early reversals. Stocks with both price and OI increasing together often signal a continuation of bullish momentum, whereas declining OI amid a fall in prices usually marks profit booking or trend exhaustion.
For instance, Hindalco shows both price and OI gains — a classic sign of bullish sentiment. In contrast, Dalbharat and Maruti reveal high OI drops, hinting at possible unwinding after recent rallies.
Traders tracking short-term setups often monitor Nifty Option Tips alongside OI trends to align with broader index momentum. This helps refine entries and exits around weekly expiry setups.
Outlook for the Coming Week
As we head into the next trading week, traders should watch the follow-up action in metals, private banks, and telecom counters. Sustained long build-ups may lead to short covering in the Nifty and Bank Nifty indices, offering trading opportunities on both sides.
Momentum traders frequently rely on updated Bank Nifty Tips for sector confirmation during weekly rollovers. A clear breakout above resistance levels in Bank Nifty could accelerate institutional long additions.
Investor Takeaway
This week’s OI build-up paints a mixed but constructive picture. Metals, banking, and select industrials look poised for more strength, while autos and pharmaceuticals may consolidate. Observing OI changes in context with price and volume can greatly enhance trade precision and risk management.
