Open Interest and Volume Dynamics
On 25 Sep 2026, Bajaj Finance’s open interest (OI) in derivatives rose sharply by 11.13%, climbing from 171,372 contracts to 190,443 contracts. This increase of 19,071 contracts is significant, indicating fresh positions being established or existing ones being rolled over. The volume for the day stood at 97,763 contracts, underscoring active trading interest in the stock’s futures and options.
The futures segment alone accounted for a value of approximately ₹2,20,859 lakhs, while the options segment exhibited an even larger notional value of ₹51,794,281,042 lakhs, culminating in a total derivatives market value of ₹2,25,004 lakhs. Such substantial figures highlight the stock’s liquidity and the scale of market engagement.
Price and Market Performance Context
Bajaj Finance’s underlying share price closed at ₹986, trading within a narrow range of just ₹0.5 on the day. Despite this tight price band, the stock outperformed its sector by 0.62%, registering a 1-day return of 0.26% compared to the sector’s decline of 0.32% and the Sensex’s marginal fall of 0.11%. This relative strength amidst broader market softness suggests selective buying interest.
Technically, the stock remains above its 200-day moving average, a long-term bullish indicator, although it is currently trading below its 5-day, 20-day, 50-day, and 100-day moving averages. This mixed technical picture points to a consolidation phase, with investors possibly awaiting clearer directional cues.
Investor Participation and Liquidity
Investor participation has notably increased, with delivery volume on 24 Sep rising by 72.79% to 72.08 lakh shares compared to the 5-day average. This surge in delivery volume indicates genuine accumulation rather than speculative intraday trading, reinforcing the stock’s appeal among long-term investors.
Liquidity remains robust, with the stock’s traded value supporting a trade size of approximately ₹16.71 crore based on 2% of the 5-day average traded value. Such liquidity ensures that institutional and retail investors can transact sizeable volumes without significant price impact.

Market Positioning and Directional Bets
The sharp rise in open interest alongside steady volume suggests that market participants are actively repositioning themselves in Bajaj Finance’s derivatives. The increase in OI by over 11% is often interpreted as a sign of fresh directional bets rather than mere unwinding of positions.
Given the stock’s large-cap status with a market capitalisation of ₹6,13,007.46 crore and a recent upgrade in its Mojo Grade from Hold to Buy (Mojo Score 71.0 as of 20 Jul 2026), investors appear increasingly confident in its medium-term prospects. The upgrade reflects improved fundamentals and positive earnings outlook, which may be driving the increased derivatives activity.
Options market data, with an enormous notional value exceeding ₹51,794 crore, indicates that traders are employing complex strategies, possibly including hedging and volatility plays. The futures market’s substantial value of ₹2,20,859 lakhs further confirms strong directional interest, likely skewed towards bullish positioning given the stock’s relative outperformance.
However, the stock’s current trading below short- and medium-term moving averages suggests some caution, with investors possibly awaiting confirmation of a breakout above these technical levels before committing further capital.
Valuation and Sector Comparison
Within the Non Banking Financial Company (NBFC) sector, Bajaj Finance continues to stand out due to its scale, liquidity, and improving fundamentals. Its recent outperformance relative to the sector (-0.32% 1-day return) and the broader Sensex (-0.11%) underscores its defensive qualities amid sectoral pressures.
The stock’s valuation remains attractive to many investors, supported by its upgraded Mojo Grade and strong market cap grade. This combination of fundamental strength and technical consolidation is likely to attract further interest from institutional investors and traders alike.

Outlook and Investor Takeaways
In summary, the surge in open interest and volume in Bajaj Finance’s derivatives signals a renewed investor focus on the stock, driven by improving fundamentals and relative strength within the NBFC sector. The upgrade in Mojo Grade to Buy reinforces the positive sentiment, suggesting that the stock is poised for potential upside once it clears near-term technical resistance levels.
Investors should monitor the evolving open interest trends and volume patterns closely, as sustained increases in these metrics often precede significant price moves. The current consolidation phase offers a strategic entry point for those looking to capitalise on the stock’s long-term growth trajectory, supported by its large-cap stature and robust market liquidity.
While the derivatives market activity points to bullish positioning, cautious investors may await confirmation through price action above the 5-day and 20-day moving averages before increasing exposure. Overall, Bajaj Finance remains a compelling pick within the NBFC space, combining strong fundamentals with active market participation.
