Open Interest and Volume Dynamics
On 12 Jun 2026, Bajaj Auto’s open interest (OI) in derivatives rose sharply to 80,714 contracts from 73,261 the previous day, marking an increase of 7,453 contracts or 10.17%. This expansion in OI is accompanied by a futures volume of 56,135 contracts, reflecting robust trading activity. The futures value stood at approximately ₹32,042 lakhs, while the options segment exhibited a substantial notional value of ₹39,747 crores, culminating in a total derivatives value of ₹37,015 lakhs. The underlying stock price was ₹10,028 at the time.
Such a rise in open interest typically indicates fresh positions being established rather than existing ones being squared off. This suggests that market participants are actively taking new stances on Bajaj Auto’s near-term price trajectory, which is particularly noteworthy given the stock’s recent price behaviour.
Price Performance and Moving Averages
Bajaj Auto has underperformed its sector by 0.89% on the day, registering a 1.02% decline compared to the sector’s marginal 0.08% fall and the Sensex’s 0.73% gain. The stock has been on a downward trend for six consecutive sessions, losing 3.3% over this period. Notably, the weighted average traded price has been closer to the day’s low, indicating selling pressure.
From a technical standpoint, the stock’s price remains above its 50-day, 100-day, and 200-day moving averages, signalling a longer-term uptrend. However, it is trading below its 5-day and 20-day moving averages, reflecting short-term weakness and potential consolidation or correction phases. This mixed technical picture aligns with the observed increase in open interest, as traders may be positioning for a directional move amid uncertainty.
Investor Participation and Liquidity Considerations
Investor participation appears to be waning, with delivery volumes on 11 Jun falling by 41.12% to 1.03 lakh shares compared to the five-day average. This decline in delivery volume suggests reduced conviction among long-term holders or a shift towards more speculative trading in the derivatives market.
Despite this, liquidity remains adequate for sizeable trades, with the stock’s traded value supporting transactions up to ₹4.94 crores based on 2% of the five-day average traded value. This liquidity profile facilitates active derivatives trading and supports the observed open interest expansion.

Market Positioning and Potential Directional Bets
The surge in open interest alongside a decline in price and volume concentration near lows suggests that traders may be initiating bearish positions or hedging existing long exposure. The fact that the stock remains above its longer-term moving averages indicates that any downside may be viewed as a correction rather than a trend reversal.
Given the large-cap status of Bajaj Auto with a market capitalisation of ₹2,81,442 crores and a strong mojo score of 80.0, upgraded recently from a Buy to a Strong Buy on 4 May 2026, institutional investors and sophisticated traders are likely recalibrating their strategies. The upgrade reflects confidence in the company’s fundamentals and growth prospects, which may encourage accumulation at lower levels despite short-term volatility.
Options market data, with an enormous notional value exceeding ₹39,747 crores, further underscores the intense interest in derivative contracts. This could imply that market participants are employing complex strategies such as spreads or straddles to capitalise on expected volatility or directional moves.
Sector and Broader Market Context
Within the automobile sector, Bajaj Auto’s recent underperformance relative to peers and the broader Sensex highlights sector-specific challenges or stock-specific profit-taking. However, the stock’s resilience above key moving averages and the strong mojo grade suggest that the underlying business remains robust.
Investors should monitor upcoming earnings, macroeconomic indicators, and sectoral developments that could influence sentiment. The derivatives market activity serves as an early barometer of expectations and risk appetite among traders.

Investor Takeaway
For investors and traders, the current open interest surge in Bajaj Auto’s derivatives market signals an active repositioning phase. While short-term price weakness and falling delivery volumes indicate caution, the stock’s strong mojo grade and large-cap stature provide a foundation for potential recovery or consolidation.
Market participants should closely watch changes in open interest alongside price and volume trends to gauge the strength of directional bets. The interplay between short-term technical signals and longer-term fundamental upgrades will be critical in shaping Bajaj Auto’s near-term trajectory.
In summary, the derivatives market activity reveals a nuanced picture of cautious optimism, with traders hedging or speculating amid a backdrop of mixed price signals. This environment offers opportunities for discerning investors to analyse positioning shifts and adjust portfolios accordingly.
