Open Interest and Volume Dynamics
On 19 Feb 2026, Bajaj Finance's open interest in futures and options contracts rose sharply to 185,079 contracts from the previous 166,884, marking an increase of 18,195 contracts or 10.9%. This expansion in OI was accompanied by a futures volume of 61,646 contracts, reflecting sustained trading interest. The combined futures and options value stood at approximately ₹24,316 crores, with futures contributing ₹2,412 crores and options an overwhelming ₹23,338 crores, underscoring the significant derivatives market activity around the stock.
The underlying stock price closed at ₹1,019, down marginally by 0.42% on the day, slightly underperforming the sector's 0.37% decline and the broader Sensex's 0.56% fall. Notably, the stock traded within a narrow range of ₹7.5, indicating subdued price volatility despite the surge in derivatives activity.
Market Positioning and Investor Behaviour
The increase in open interest amid a slight price dip suggests that market participants are actively building positions, potentially anticipating a directional move. The fact that Bajaj Finance is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages indicates an underlying bullish trend, despite the short-term price pullback.
However, delivery volumes tell a different story. On 18 Feb, the delivery volume fell sharply by 42.46% to 41.26 lakh shares compared to the 5-day average, signalling reduced investor participation in the cash segment. This divergence between derivatives activity and cash market participation may imply that traders are increasingly relying on leveraged instruments to express their views rather than outright stock purchases.
Sector and Market Context
Bajaj Finance operates within the NBFC sector, which has been under pressure due to tightening liquidity conditions and regulatory scrutiny. Despite these headwinds, the company maintains a robust market capitalisation of ₹6,34,413 crore, categorising it as a large-cap stock with a Market Cap Grade of 1. The recent downgrade in its Mojo Grade from Buy to Hold on 1 Feb 2026, with a current Mojo Score of 65.0, reflects a cautious stance by analysts amid evolving market conditions.

Interpreting the Derivatives Activity
The surge in open interest, particularly in options contracts valued at over ₹23,338 crores, points to increased hedging and speculative activity. Market participants may be positioning for potential volatility or directional moves in Bajaj Finance’s stock price. The narrow trading range and the stock’s position above key moving averages suggest that investors are weighing the possibility of a rebound after the recent two-day consecutive gains were reversed.
Given the stock’s liquidity profile, with an average tradable value supporting trade sizes up to ₹22.7 crore, institutional investors and high-frequency traders can efficiently execute sizeable positions. This liquidity, combined with the derivatives market activity, could lead to amplified price movements if a catalyst emerges.
Potential Directional Bets and Risks
While the open interest increase often signals fresh capital entering the market, the mixed signals from price action and falling delivery volumes suggest caution. Some traders may be betting on a short-term correction or consolidation, utilising options strategies such as spreads or straddles to capitalise on expected volatility without directional bias.
Conversely, the stock’s strong technical positioning above multiple moving averages and its large-cap status may attract long-term investors seeking value amid sectoral uncertainties. The downgrade to a Hold rating by MarketsMOJO reflects this balanced outlook, advising investors to monitor developments closely before committing fresh capital.

Outlook and Investor Considerations
Investors should closely monitor the evolving open interest trends and volume patterns in Bajaj Finance’s derivatives market as indicators of potential price direction. The current environment suggests a market in wait-and-watch mode, with participants hedging their positions amid sectoral challenges and broader market volatility.
Given the stock’s recent technical strength but short-term price softness, a cautious approach is warranted. Investors may consider waiting for confirmation of trend direction or clearer signals from delivery volumes and price momentum before increasing exposure.
In summary, the significant open interest surge in Bajaj Finance’s derivatives points to active market positioning and potential volatility ahead. However, the mixed signals from price action and investor participation highlight the need for careful analysis and risk management in portfolio decisions.
