Open Interest and Volume Dynamics
The latest open interest (OI) for Bajaj Finance Ltd’s derivatives rose sharply to 1,80,737 contracts from the previous 1,63,814, marking an increase of 16,923 contracts or 10.33%. This expansion in OI occurred alongside a volume of 1,15,349 contracts traded, indicating robust participation in the futures and options market. The futures value stood at ₹2,34,394.02 lakhs, while the options segment accounted for an enormous ₹52,252.96 crores, culminating in a total derivatives value of approximately ₹2,41,525 lakhs.
This spike in open interest amidst a declining stock price suggests that fresh positions are being initiated rather than existing ones being squared off. The stock’s underlying value closed at ₹848, down 3.84% on the day, underperforming its sector by 1.38% and the broader Sensex by 2.27%. Intraday, the stock touched a low of ₹846, with the weighted average price skewed towards the lower end, signalling selling pressure.
Price Trends and Moving Averages
Bajaj Finance’s price action reveals a trend reversal after two consecutive days of gains. The stock currently trades above its 5-day moving average but remains below its 20-day, 50-day, 100-day, and 200-day moving averages, indicating a mixed technical picture. The short-term momentum is positive, but medium to long-term trends remain subdued, reflecting investor caution amid broader sector weakness.
The Finance/NBFC sector itself declined by 2.67% on the day, amplifying the pressure on Bajaj Finance. However, rising investor participation is evident from the delivery volume of 1.14 crore shares on 25 Mar, which surged 28.21% above the five-day average, highlighting increased interest in the stock despite recent weakness.

Market Positioning and Directional Bets
The surge in open interest amid falling prices typically signals that traders are either building fresh short positions or hedging existing long exposure. Given Bajaj Finance’s current Mojo Score of 46.0 and a downgrade from Hold to Sell on 23 Mar 2026, market participants appear to be positioning for further downside or increased volatility.
Notably, the stock’s large-cap status with a market capitalisation of ₹5,27,915.36 crores ensures ample liquidity, with a trade size capacity of ₹27.22 crores based on 2% of the five-day average traded value. This liquidity supports active derivatives trading and facilitates sizeable institutional participation.
Volume patterns reveal that more trades occurred near the day’s low price, reinforcing bearish sentiment. The divergence between rising open interest and declining price suggests that short sellers are confident in a continued downward trajectory or that hedgers are protecting against downside risks in their portfolios.
Sectoral and Broader Market Context
The NBFC sector’s decline of 2.67% on the day, coupled with Bajaj Finance’s sharper 3.84% drop, reflects sector-specific headwinds possibly related to tightening credit conditions or macroeconomic concerns. The Sensex’s modest 1.57% fall indicates that the pressure is more concentrated within financials, particularly NBFCs.
Investors should also note the stock’s technical positioning relative to moving averages, which suggests that while short-term momentum may offer some support, medium-term trends remain under pressure. This mixed technical outlook, combined with the open interest surge, points to a market bracing for potential volatility or a directional shift.

Implications for Investors
For investors, the current derivatives activity in Bajaj Finance Ltd signals caution. The downgrade to a Sell rating by MarketsMOJO, combined with the open interest surge and price weakness, suggests that downside risks are being priced in. Investors should carefully monitor the stock’s ability to hold key support levels and watch for any reversal in volume and open interest trends that might indicate a shift in market sentiment.
Given the stock’s liquidity and active derivatives market, traders may find opportunities to hedge or speculate on directional moves. However, the prevailing technical and fundamental signals counsel prudence, especially in the context of broader sector weakness and macroeconomic uncertainties.
Conclusion
Bajaj Finance Ltd’s recent open interest surge amid a declining price environment highlights a complex interplay of market forces. While increased participation reflects strong investor interest, the directional bias appears tilted towards caution or bearishness. The stock’s downgrade to Sell and underperformance relative to its sector and the Sensex reinforce this outlook. Investors and traders should remain vigilant, leveraging both fundamental and technical indicators to navigate the evolving landscape in this key NBFC large cap.
