At-the-Money Calls on Bajaj Auto Ltd. Draw 15,843 Contracts — A Signal of Immediate Directional Conviction

Options Event and Cash Market Price Action

The most active call option on Bajaj Auto Ltd. on 22 Jul 2026 was the Rs 10,800 strike expiring on 28 Jul 2026, with 15,843 contracts traded. This turnover amounted to approximately ₹1520.7 lakhs, reflecting significant liquidity at this strike. The underlying stock closed at Rs 10,803, just above the strike price, reinforcing the at-the-money (ATM) nature of this option. The proximity of the strike to the current price suggests that traders are positioning for immediate directional movement rather than a distant target.

Alongside this, other strikes saw notable activity: Rs 10,700 calls traded 12,199 contracts, Rs 10,900 calls 9,239 contracts, Rs 10,600 calls 8,399 contracts, and Rs 10,500 calls 9,843 contracts. The underlying stock’s 3.16% gain on the day, outperforming the sector by 0.94%, aligns with the surge in call buying — Bajaj Auto Ltd. is clearly in focus across both cash and derivatives markets. Is this momentum sustainable or a short-term spike ahead of expiry?

Strike Price and Moneyness Analysis

The Rs 10,800 strike is effectively at-the-money given the stock’s closing price of Rs 10,803. ATM options are the most sensitive to price changes in the underlying, exhibiting the highest gamma. This means that small moves in Bajaj Auto Ltd. will have a magnified impact on the option’s value, indicating a bet on near-term directional movement rather than a speculative long-term target.

Strikes slightly out-of-the-money (OTM) such as Rs 10,900 and Rs 10,600 also saw heavy volumes, but the concentration at Rs 10,800 suggests traders are focusing on the immediate price level. The Rs 10,500 strike, in-the-money (ITM) relative to the current price, attracted 9,843 contracts, which may indicate some hedging or deeper conviction positions. What does this blend of strikes reveal about the market’s directional confidence?

Open Interest and Contracts Analysis

Open interest (OI) at the Rs 10,800 strike stands at 2,511 contracts, while 15,843 contracts traded on the day. This yields a contracts-to-OI ratio of approximately 6.3:1, a notably high figure that points to predominantly fresh positioning rather than existing holders trading their options. Similarly, the Rs 10,700 strike has an OI of 1,399 against 12,199 contracts traded, reinforcing the theme of new money entering the call options market.

In contrast, the Rs 10,500 strike has a higher OI of 3,315 but fewer contracts traded (9,843), suggesting a mix of fresh and existing positions. The Rs 10,900 strike’s OI of 1,618 against 9,239 contracts traded also indicates fresh activity but with a slightly lower ratio than the ATM strike. This pattern of high turnover relative to OI across strikes signals a broad-based directional interest in calls rather than mere position adjustments.

Cash Market Context: Price Momentum and Moving Averages

Bajaj Auto Ltd. has been on a strong upward trajectory, hitting a new 52-week high of Rs 10,838 on 22 Jul 2026. The stock is trading comfortably above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, signalling robust technical strength. The 3.16% gain on the day outpaced the sector’s 2.05% rise and the Sensex’s decline of 0.66%, underscoring the stock’s relative outperformance.

This technical backdrop aligns well with the surge in call option activity, particularly at the ATM strike, where traders appear to be betting on continued momentum. The options market is not running ahead of the cash market but rather confirming the ongoing strength in Bajaj Auto Ltd.. Does this alignment suggest a sustained trend or a near-term peak?

Delivery Volume and Market Participation

Delivery volumes on 21 Jul 2026 rose to 4.11 lakh shares, a 33.47% increase over the 5-day average, indicating heightened investor participation in the cash market. This rise in delivery volume supports the conviction seen in the derivatives market, as genuine buying interest is reflected in actual share transfers rather than just speculative trading.

The liquidity of the stock remains strong, with the ability to handle trade sizes of approximately ₹10.68 crores based on 2% of the 5-day average traded value. This ensures that the options activity is backed by a liquid underlying, reducing the risk of price distortions. The delivery volume increase alongside call buying suggests the options market’s directional bets are grounded in real cash market demand.

Key Data at a Glance

Conclusion: What the Options and Cash Data Collectively Signal

The concentration of call contracts at the Rs 10,800 strike, nearly identical to the stock’s closing price, indicates a precise directional wager on near-term upside for Bajaj Auto Ltd.. The high contracts-to-open interest ratio points to fresh money entering the market, rather than recycling of existing positions. This is complemented by strong price momentum, with the stock trading above all major moving averages and hitting a new 52-week high.

Moreover, the rise in delivery volumes confirms genuine cash market participation, lending further credibility to the bullish options positioning. The alignment between derivatives and cash markets suggests confidence in the current trend, though the proximity of expiry on 28 Jul 2026 adds urgency to these bets. Is this a momentum play worth joining or has the easy move already happened?
