Robust Call Option Trading Highlights Bullish Sentiment
On 27 August 2026, Bajaj Finance Ltd witnessed an impressive 3,997 call option contracts traded for the 29 September 2026 expiry at the ₹1,100 strike price. This activity generated a turnover of ₹916.11 lakhs, underscoring substantial investor interest in leveraged bullish bets on the stock. The open interest for these call options stands at 3,408 contracts, indicating sustained positions held by market participants anticipating further upside.
The underlying stock price at the time was ₹1,094.10, just below the strike price, suggesting that traders are positioning for a potential rally beyond the ₹1,100 level within the next month. This is a notable development given the stock’s recent trading range and technical indicators.
Price Performance and Technical Context
Bajaj Finance Ltd outperformed its NBFC sector by 0.87% on the day, registering a 1-day return of 0.83% compared to the sector’s marginal decline of 0.04% and the Sensex’s near-flat movement at -0.01%. The stock traded within a narrow intraday range of ₹1.2, reflecting a consolidation phase ahead of the expiry.
Technically, the stock is trading above its 5-day, 50-day, 100-day, and 200-day moving averages, signalling a strong medium- to long-term uptrend. However, it remains slightly below the 20-day moving average, which may act as a short-term resistance level. This mixed technical picture could explain the cautious yet optimistic positioning seen in the options market.
Investor Participation and Liquidity Considerations
Despite the bullish option activity, investor participation in the underlying stock has shown signs of moderation. Delivery volume on 26 August was 19.59 lakh shares, down by 26.24% compared to the 5-day average delivery volume. This decline suggests some profit-booking or cautious stance among long-term holders, even as traders ramp up call option exposure.
Liquidity remains adequate for sizeable trades, with the stock’s average traded value supporting transaction sizes up to ₹9.15 crore based on 2% of the 5-day average traded value. This ensures that both spot and derivatives market participants can execute large orders without significant price impact.
Fundamental Backdrop and Rating Upgrade
Bajaj Finance Ltd, a large-cap NBFC with a market capitalisation of ₹6,81,119.40 crore, recently received an upgrade in its Mojo Grade from Hold to Buy on 20 July 2026. The company’s Mojo Score stands at a robust 78.0, reflecting strong fundamentals, quality of earnings, and favourable growth prospects within the non-banking financial sector.
This upgrade has likely contributed to the increased bullish sentiment in the options market, as institutional and retail investors recalibrate their outlook on the stock’s medium-term trajectory. The company’s consistent performance and leadership in consumer finance continue to underpin investor confidence.
Expiry Patterns and Strategic Implications
The concentration of call option activity at the ₹1,100 strike price for the 29 September expiry is particularly telling. It suggests that traders expect the stock to breach this level within the next month, potentially driven by upcoming earnings announcements, macroeconomic factors, or sectoral tailwinds.
Such positioning often precedes volatility spikes as expiry approaches, with market makers and institutional players adjusting their hedges accordingly. Investors should monitor open interest changes and price movements closely to gauge the sustainability of this bullish momentum.
Balancing Optimism with Caution
While the surge in call option volumes and the recent rating upgrade paint a positive picture, investors should remain mindful of the stock’s near-term technical resistance and the dip in delivery volumes. These factors indicate that some market participants may be adopting a wait-and-watch approach, awaiting clearer directional cues.
Moreover, broader market conditions and sectoral developments in the NBFC space could influence Bajaj Finance’s price action in the coming weeks. As such, a balanced strategy combining spot holdings with selective option positions may be prudent for investors seeking to capitalise on the current bullish sentiment.
Conclusion
Bajaj Finance Ltd’s prominence as the most active stock in call options trading ahead of the 29 September 2026 expiry highlights strong bullish conviction among traders. The ₹1,100 strike price has emerged as a key level, with substantial open interest and turnover signalling expectations of upward price movement.
Supported by a recent upgrade to a Buy rating and solid fundamental metrics, the stock’s technical setup remains favourable despite some short-term resistance. Investors should continue to monitor option market dynamics alongside price and volume trends to navigate the evolving landscape effectively.
