Bajaj Finance Sees Significant Open Interest Surge Amid Mixed Technical Signals

Open Interest and Volume Dynamics

On 22 Jan 2026, Bajaj Finance’s open interest (OI) rose sharply to 2,28,237 contracts from 1,94,529 the previous day, marking an increase of 33,708 contracts or 17.33%. This surge in OI was accompanied by a futures volume of 1,13,632 contracts, reflecting active participation in the derivatives market. The futures value stood at ₹4,42,405.65 lakhs, while the options segment exhibited an enormous notional value of ₹37,118.11 crores, culminating in a total derivatives value of approximately ₹4,46,184 lakhs.

The underlying stock price closed at ₹938, aligning closely with sector performance, which gained 0.68% on the day, while the Sensex rose 0.19%. Bajaj Finance’s 1-day return of 0.45% was slightly below the sector average but above the broader market benchmark.

Technical and Market Positioning Insights

Despite the positive price movement, Bajaj Finance is currently trading below all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — indicating a prevailing bearish technical backdrop. This divergence between price gains and moving average positioning suggests that short-term traders may be positioning for a rebound, while longer-term investors remain cautious.

Investor participation appears to be waning, with delivery volumes on 21 Jan falling by 34.19% to 31.79 lakh shares compared to the 5-day average. This decline in delivery volume may imply reduced conviction among long-term holders, even as derivatives activity intensifies.

Liquidity remains robust, with the stock’s average traded value supporting trade sizes up to ₹14.61 crores, ensuring that institutional investors can execute sizeable positions without significant market impact.

Interpreting the Open Interest Surge

The 17.3% increase in open interest is a significant development, often interpreted as fresh capital entering the market or existing participants increasing their exposure. In Bajaj Finance’s case, this rise in OI alongside a moderate price gain suggests that traders may be building directional bets, possibly anticipating a near-term recovery or volatility spike.

Given the stock’s position below all major moving averages, the open interest build-up could reflect speculative long positions taken by traders expecting a technical bounce. Alternatively, it might also indicate hedging activity by institutional players preparing for potential downside risks amid broader market uncertainties.

The large notional value in options contracts further supports the notion of active hedging and strategic positioning, with market participants likely employing a mix of calls and puts to manage risk or capitalise on expected price swings.

Mojo Score and Analyst Ratings

Bajaj Finance currently holds a Mojo Score of 71.0, categorised as a Buy rating by MarketsMOJO. This represents a slight downgrade from its previous Strong Buy grade assigned on 21 Jan 2025, reflecting a more cautious stance amid recent price and volume trends. The company’s market capitalisation stands at a substantial ₹5,85,224.42 crores, affirming its large-cap status within the NBFC sector.

The downgrade in rating may be attributed to the stock’s technical weakness and falling investor participation, despite the encouraging derivatives activity. Analysts appear to be balancing the company’s strong fundamentals against near-term market headwinds and valuation concerns.

Sector and Market Context

The NBFC sector has experienced mixed performance recently, with some players benefiting from improving credit demand and others facing challenges from rising interest rates and regulatory scrutiny. Bajaj Finance’s performance, in line with sector gains but lagging slightly, reflects this nuanced environment.

Investors should note that while derivatives data points to increased interest and potential directional bets, the underlying fundamentals and macroeconomic factors remain critical in shaping the stock’s medium-term trajectory.

Investor Takeaways and Outlook

For investors, the recent surge in open interest in Bajaj Finance’s derivatives signals an active market positioning phase. The mixed technical signals — with price gains offset by weakness below key moving averages and declining delivery volumes — suggest that caution is warranted.

Short-term traders may view the increased OI as an opportunity to capitalise on potential volatility or a rebound, while long-term investors should monitor fundamental developments and sector trends closely. The downgrade from Strong Buy to Buy by MarketsMOJO reflects this balanced view, acknowledging the company’s robust fundamentals but recognising the current technical and market challenges.

Overall, Bajaj Finance remains a key player in the NBFC sector with strong market capitalisation and liquidity. However, the evolving derivatives activity and technical backdrop underscore the importance of a nuanced approach, combining fundamental analysis with close attention to market positioning and volume patterns.

Conclusion

The significant increase in open interest for Bajaj Finance Ltd highlights a period of heightened market engagement and potential directional bets among traders. While the stock’s price performance remains modest and technical indicators suggest caution, the derivatives market activity points to an expectation of near-term movement, either as a rebound or increased volatility.

Investors should weigh these factors carefully, considering both the company’s strong fundamentals and the current market environment. Monitoring open interest trends alongside price and volume data will be crucial in assessing future opportunities and risks in this large-cap NBFC stock.
