Robust Put Option Volumes Signal Market Caution
The two-wheeler giant Bajaj Auto (NSE: BAJAJ-AUTO) recorded significant put option volumes across multiple strike prices for the expiry on 26 May 2026. The most active strikes were ₹10,500, ₹10,300, ₹10,600, ₹10,400, and ₹10,200, with the highest number of contracts traded at the ₹10,500 strike, tallying 3,583 contracts. This was followed by 2,820 contracts at ₹10,300 and 2,207 contracts at ₹10,400.
Turnover in these put options was substantial, with the ₹10,500 strike alone generating ₹717.6 lakhs in turnover, while the ₹10,600 and ₹10,400 strikes accounted for ₹473.6 lakhs and ₹384.7 lakhs respectively. Open interest remains elevated, particularly at the ₹10,300 strike with 1,668 contracts outstanding, indicating sustained bearish interest or protective hedging at these levels.
Underlying Stock Performance Contrasts Put Activity
Interestingly, Bajaj Auto’s underlying stock price has been resilient, hitting a new 52-week high of ₹10,656 on 7 May 2026. The stock outperformed its sector by 0.52% on the day, rising 3.62% compared to the Automobile Two & Three Wheelers sector gain of 2.52% and the Sensex’s modest 0.26% advance. The stock has gained 5.64% over the past two days, supported by a strong gap-up opening of 2.55% on 7 May.
Technical indicators also remain bullish, with the share price trading above all key moving averages – 5-day, 20-day, 50-day, 100-day, and 200-day – underscoring positive momentum. However, delivery volumes have declined sharply by 42.81% against the five-day average, suggesting a possible reduction in long-term investor participation despite the price rally.
Mojo Score Upgrade Reflects Positive Fundamentals
Bajaj Auto’s recent upgrade from a Buy to a Strong Buy rating on 4 May 2026, accompanied by a robust Mojo Score of 80.0, highlights the company’s strong fundamentals and favourable outlook. The large-cap stock, with a market capitalisation of ₹2,98,867.04 crores, continues to be a key player in the automobile sector, particularly in two and three-wheelers.
Despite this positive fundamental backdrop, the surge in put option activity suggests that market participants are either positioning for a near-term correction or employing puts as a hedge against potential volatility ahead of the May expiry. The concentration of open interest and turnover around strikes slightly below the current market price indicates a cautious stance, possibly reflecting concerns over valuation or broader market uncertainties.
Expiry Patterns and Investor Sentiment
The expiry on 26 May 2026 is attracting heightened attention, with Bajaj Auto’s put options dominating the most active list. The clustering of activity in strikes ranging from ₹10,200 to ₹10,600, all close to the current underlying price of ₹10,641, points to a strategic hedging zone. Investors may be seeking downside protection in case of a pullback, while others could be speculating on a short-term correction.
Such heavy put option volumes often precede increased volatility, as traders adjust their positions in response to evolving market conditions. The elevated open interest at these strikes also implies that a significant number of contracts remain open, which could influence price movements as expiry approaches.
Balancing Bullish Fundamentals with Bearish Option Flows
The juxtaposition of Bajaj Auto’s strong price performance and fundamental upgrade against the backdrop of heavy put option trading presents a nuanced picture. While the company’s operational metrics and sectoral tailwinds remain intact, the options market is signalling caution, possibly reflecting profit-taking, risk management, or anticipation of near-term volatility.
For investors, this dynamic underscores the importance of monitoring both the underlying stock’s technicals and the derivatives market to gauge sentiment shifts. The put option activity could serve as an early warning for a potential correction or a temporary pause in the rally, especially if broader market conditions deteriorate.
Outlook and Strategic Considerations
Given Bajaj Auto’s large-cap status and liquidity, the stock remains an attractive proposition for long-term investors, supported by its recent upgrade and strong sectoral performance. However, the pronounced put option activity ahead of the May expiry suggests that traders and institutional investors are actively managing downside risk.
Market participants should watch for changes in open interest and volume in the coming days, as well as any shifts in the stock’s price relative to key strike prices. A sustained breach below the ₹10,300 to ₹10,500 range could trigger further downside, while a firm hold above these levels may reinforce the bullish case.
In summary, Bajaj Auto’s options market activity provides valuable insight into investor psychology, highlighting a blend of optimism tempered by prudent risk management as expiry approaches.
