Open Interest and Volume Dynamics
The latest data reveals that Bajaj Finserv’s open interest (OI) in derivatives rose from 1,10,752 contracts to 1,26,362 contracts, an increase of 15,610 contracts or 14.09% on 29 Dec 2025. This expansion in OI is accompanied by a daily volume of 45,771 contracts, indicating robust trading activity. The futures segment alone accounted for a value of approximately ₹90,817 lakhs, while options contributed a staggering ₹14,202 crore, culminating in a total derivatives value of ₹91,911 lakhs.
Such a pronounced rise in open interest amid a declining stock price suggests that new positions are being established rather than existing ones being squared off. This often points to increased speculative interest or hedging activity, reflecting divergent views on the stock’s near-term trajectory.
Price Performance and Moving Averages
Bajaj Finserv’s underlying share price closed at ₹2,004, down 0.64% on the day, slightly underperforming the sector’s decline of 0.50% and the Sensex’s 0.32% fall. The stock has been on a four-day losing streak, cumulatively shedding 2.18% in value. Notably, the share is trading below all key moving averages—5-day, 20-day, 50-day, 100-day, and 200-day—indicating a sustained bearish trend and weak technical momentum.
Investor participation has, however, been rising, with delivery volumes on 26 Dec reaching 12.82 lakh shares, a sharp 95.72% increase over the five-day average. This suggests that despite the price decline, longer-term investors may be accumulating shares, potentially anticipating a reversal or valuing the stock’s fundamentals.

Market Positioning and Directional Bets
The surge in open interest alongside rising volumes points to a shift in market positioning. Traders appear to be taking fresh stances, possibly anticipating volatility or directional moves. Given the stock’s recent underperformance and technical weakness, the increased OI could reflect a mix of bearish bets through futures short positions or protective put options, as well as contrarian long bets by value investors.
Options data, with a total value exceeding ₹14,202 crore, underscores significant activity in the options market. This may indicate hedging strategies by institutional investors or speculative plays on expected price swings. The large notional value in options relative to futures suggests a preference for asymmetric risk strategies, where investors seek to limit downside while retaining upside potential.
Fundamental and Technical Assessment
Bajaj Finserv, a large-cap holding company with a market capitalisation of ₹3,20,298 crore, currently holds a Mojo Score of 60.0 and a Mojo Grade of Hold. This represents a downgrade from a Buy rating issued on 6 Oct 2025, reflecting a reassessment of the stock’s near-term outlook amid sectoral pressures and broader market volatility.
The company’s market cap grade remains at 1, indicating its status as a heavyweight in the index. However, the downgrade signals caution, as the stock struggles to sustain momentum and faces resistance at multiple moving averages. Investors should weigh these technical headwinds against the company’s underlying fundamentals and sector positioning.
Liquidity and Trading Considerations
Liquidity remains adequate for sizeable trades, with the stock’s average traded value supporting a trade size of approximately ₹4.93 crore based on 2% of the five-day average. This ensures that institutional and retail investors can enter or exit positions without significant market impact, an important factor given the heightened derivatives activity.
Given the current environment, market participants should monitor open interest trends closely, as sustained increases in OI during price declines often precede sharp reversals or confirm bearish momentum. The interplay between futures and options volumes will also provide clues on whether the market consensus is shifting towards risk-off or selective accumulation.

Outlook and Investor Takeaways
In summary, the recent spike in open interest for Bajaj Finserv’s derivatives amid a declining price trend highlights a complex market scenario. While technical indicators suggest caution, the rising delivery volumes and active options market hint at nuanced positioning by investors.
For investors, this environment calls for a balanced approach. Those with a bullish outlook may consider selective accumulation on dips, supported by improving delivery volumes and the company’s large-cap stature. Conversely, traders wary of further downside should monitor open interest and volume patterns for signs of intensifying bearish bets or volatility spikes.
Ultimately, the stock’s downgraded Mojo Grade to Hold reflects the need for prudence, with a watchful eye on both fundamental developments and technical signals in the coming weeks.
