This surge in OI is accompanied by a substantial volume of 39,874 contracts traded, indicating heightened activity and fresh positions being established by market participants.

Such figures underscore the significant liquidity and interest in Bajaj Finserv's derivatives, making it a focal point for traders and investors alike.

Price Performance and Moving Averages

Bajaj Finserv's underlying stock price closed at ₹2,059, outperforming its sector by 0.48% and delivering a 1.27% gain on the day, compared to the sector's 0.70% and Sensex's 0.61% returns. The stock is trading above all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling a strong bullish trend and sustained investor confidence.

Additionally, delivery volumes surged to 4.33 lakh shares on 19 February, a 25.64% increase over the 5-day average delivery volume, reflecting rising investor participation and conviction in the stock's upward trajectory.

Market Capitalisation and Quality Assessment

With a market capitalisation of ₹3,29,553.24 crores, Bajaj Finserv firmly holds its position as a large-cap entity within the holding company sector. The company’s Mojo Score currently stands at 50.0, with a Mojo Grade upgraded from Sell to Hold on 18 February 2026, indicating a cautious but improving outlook from analysts. The market cap grade remains at 1, reflecting its significant size and influence in the market.

Interpreting the Open Interest Surge

The 11.44% increase in open interest, coupled with rising volumes, suggests that new positions are being initiated rather than existing ones being squared off. This typically indicates fresh capital inflows and a strengthening conviction among traders. Given the stock’s outperformance relative to its sector and the Sensex, the directional bias appears to be bullish.

Moreover, the fact that Bajaj Finserv is trading above all major moving averages reinforces the technical strength and supports the notion of sustained upward momentum. The increased delivery volumes further confirm that investors are not merely trading intraday but are willing to hold shares, signalling confidence in the company’s fundamentals and growth prospects.

Potential Directional Bets and Market Positioning

Market participants seem to be positioning for continued upside in Bajaj Finserv. The substantial open interest in options, with a notional value exceeding ₹12,779 crores, indicates active hedging and speculative activity. Call options are likely being accumulated as bullish bets, while put options may be used for protection or speculative short positions.

Given the stock’s recent upgrade from Sell to Hold and the stable Mojo Score, investors may be cautiously optimistic, balancing the potential for gains with the need for risk management. The liquidity profile, with the stock capable of handling trade sizes up to ₹2.65 crores based on 2% of the 5-day average traded value, makes it attractive for institutional investors and large traders seeking to build or adjust positions.

Sector and Broader Market Context

Bajaj Finserv operates within the holding company sector, which has seen mixed performance in recent months. The stock’s ability to outperform its sector by 0.48% on the day of the open interest surge highlights its relative strength. This outperformance, combined with technical and volume indicators, may attract further interest from investors seeking exposure to quality large-cap holdings with growth potential.

Investor Takeaways and Outlook

For investors, the recent surge in open interest and volume in Bajaj Finserv’s derivatives signals a period of heightened activity and potential price discovery. The stock’s technical strength, combined with improving analyst sentiment, suggests that it could continue to attract buying interest in the near term.

However, the Hold Mojo Grade indicates that while the outlook is improving, caution remains warranted. Investors should monitor open interest trends, volume patterns, and price action closely to gauge whether the bullish momentum sustains or if profit-taking emerges.

Given the stock’s liquidity and market cap, it remains a viable option for both retail and institutional investors looking to capitalise on the holding company’s growth prospects while managing risk prudently.

Conclusion

Bajaj Finserv Ltd’s recent open interest surge in derivatives, coupled with strong volume and price performance, reflects a positive shift in market positioning. The stock’s outperformance relative to its sector and the Sensex, along with rising delivery volumes and trading above key moving averages, underscores a bullish technical setup. While the Mojo Grade remains at Hold, the upgrade from Sell signals improving fundamentals and market sentiment. Investors should consider these factors carefully as they evaluate their exposure to this large-cap holding company amid evolving market dynamics.
