Open Interest and Volume Dynamics
On 4 May 2026, Bajaj Auto's open interest (OI) in derivatives rose sharply by 7,669 contracts, a 12.45% increase from the previous figure of 61,618 to 69,287. This expansion in OI was accompanied by a substantial volume of 114,962 contracts traded, reflecting heightened activity in both futures and options segments. The futures value stood at approximately ₹65,020 lakhs, while the options value was significantly larger at ₹84,323.79 crores, culminating in a total derivatives value of ₹80,784.28 lakhs.
The underlying stock price also demonstrated strong momentum, closing at ₹10,095, with an intraday high reaching ₹10,477.5 — a new 52-week peak. The stock outperformed its sector by 0.54% and the broader Sensex by 0.79% on the day, registering a 1.09% gain. Notably, Bajaj Auto has been on a three-day consecutive gain streak, delivering a cumulative return of 6.1% during this period.
Market Positioning and Technical Indicators
The surge in open interest alongside rising prices typically indicates fresh long positions being established, suggesting bullish sentiment among market participants. Bajaj Auto’s price currently trades above all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — reinforcing the positive technical outlook. The stock opened with a gap-up of 2.5%, further underscoring strong buying interest at the market open.
Investor participation has also intensified, with delivery volumes on 30 April reaching 4.76 lakh shares, a remarkable 238.54% increase compared to the five-day average delivery volume. This surge in delivery volumes points to genuine accumulation rather than speculative trading, which often accompanies derivative activity.

Implications of the Open Interest Surge
The 12.45% rise in open interest amid a price rally suggests that traders are increasingly confident in the stock’s upward trajectory. This pattern often reflects fresh long positions being added rather than short covering, which would typically coincide with a decline in open interest. The combination of rising OI and price is a classic confirmation of bullish market positioning.
Moreover, the substantial options value relative to futures indicates active hedging and speculative strategies in the options market. The large notional value in options could imply that market participants are positioning for continued volatility or directional moves, possibly through call buying or protective put strategies.
Sector and Market Context
Bajaj Auto operates within the automobiles sector, a space that has shown moderate gains recently. The stock’s 1.17% one-day return outpaced the sector’s 0.41% and the Sensex’s 0.38%, highlighting its relative strength. With a market capitalisation of ₹2,90,119 crores, Bajaj Auto is classified as a large-cap stock, attracting institutional interest and liquidity. The stock’s liquidity supports sizeable trade sizes, with an estimated tradable value of ₹8.41 crores based on 2% of the five-day average traded value.
Mojo Score and Analyst Ratings
MarketsMOJO assigns Bajaj Auto a Mojo Score of 67.0, categorising it with a Hold rating. This represents a downgrade from a previous Buy rating issued on 9 March 2026. The downgrade reflects a more cautious stance amid recent price gains and elevated valuations. Investors should weigh the strong technical momentum against the tempered fundamental outlook and valuation considerations.

Investor Takeaway
The recent surge in open interest and volume in Bajaj Auto’s derivatives market, coupled with a strong price rally and rising delivery volumes, points to a bullish market consensus. Traders appear to be positioning for further upside, supported by technical strength and sustained investor interest. However, the recent downgrade to a Hold rating by MarketsMOJO suggests that investors should remain vigilant about valuation risks and broader market conditions.
Given the stock’s large-cap status and liquidity, Bajaj Auto remains an attractive option for investors seeking exposure to the automobile sector’s growth prospects. Yet, the mixed signals from fundamental ratings and technical momentum warrant a balanced approach, combining careful monitoring of open interest trends with broader market analysis.
Conclusion
Bajaj Auto Ltd.’s derivatives market activity reveals a clear shift in market positioning, with a significant increase in open interest and volume supporting a bullish outlook. The stock’s new 52-week high and outperformance relative to sector and benchmark indices reinforce this positive sentiment. Nonetheless, investors should consider the recent rating downgrade and maintain a disciplined approach to risk management as they evaluate potential directional bets in this large-cap automobile stock.
