28 September 2026: Intraday Low Amid Price Pressure
Bajaj Auto Ltd opened the week under pressure, closing at Rs.11,009.00, down 2.92% from the previous Friday’s close of Rs.11,340.00. The stock hit an intraday low of Rs.10,958, reflecting a 3.37% drop from the prior close. This decline outpaced the Automobile Two & Three Wheelers sector’s 2.04% fall and the Sensex’s 1.60% drop, signalling specific selling interest in the stock amid broader market weakness.
Technical indicators showed the stock trading below its short-term moving averages but still supported by its 100-day and 200-day averages, suggesting some longer-term resilience. However, the immediate trend was bearish, with the Sensex itself nearing a 52-week low and exhibiting a three-week losing streak.
29 September 2026: Continued Downtrend
The downward momentum persisted on 29 September, with Bajaj Auto closing at Rs.10,819.00, a further 1.73% decline. The Sensex also fell by 0.48%, but the stock’s sharper drop indicated ongoing pressure. Volume remained steady, reflecting sustained investor interest despite the negative sentiment.
30 September 2026: Slight Recovery
On 30 September, Bajaj Auto saw a modest rebound, closing at Rs.10,860.00, up 0.38%. This minor recovery came amid a marginal Sensex decline of 0.17%, suggesting some short-term consolidation after two days of losses. The stock’s technical indicators remained mixed, with the MACD bullish on weekly and monthly charts but short-term averages still under pressure.

1 October 2026: Sharp Decline and Elevated Derivatives Activity
The most significant move of the week occurred on 1 October, when Bajaj Auto’s stock price plunged 7.28% intraday, closing at Rs.10,069.85, down 11.20% from the previous Friday’s close. The stock touched an intraday low of Rs.10,386.9 and opened sharply lower at Rs.10,701, reflecting intense selling pressure amid a cautious market environment.
Volume surged dramatically to 73,236 shares, with a total traded value nearing ₹196 crores, making Bajaj Auto one of the most actively traded stocks by value. Despite this liquidity, the stock underperformed both its sector, which declined 3.47%, and the Sensex, which fell 0.99% that day.
Derivatives activity was particularly notable, with open interest surging 19.02% to 55,207 contracts. Call options at strike prices ₹10,500 and ₹11,000 saw heavy trading, alongside a significant spike in put option volumes at strikes ₹10,300 and ₹10,500. This mixed but elevated options activity suggests a complex market positioning, with investors hedging and speculating amid uncertainty.
Technically, the stock traded below its 5-day, 20-day, 50-day, and 100-day moving averages but remained above the 200-day average, indicating short-term weakness within a longer-term uptrend. The weighted average price indicated most trades occurred near the day’s low, underscoring selling dominance.
Delivery volumes increased by 31.22% compared to the five-day average, signalling genuine investor participation rather than purely speculative trading. Institutional interest appears to be accumulating at lower levels, possibly anticipating a rebound or valuing the stock’s fundamentals despite sector headwinds.
Derivatives Market Insights: Mixed Sentiment Ahead of October Expiry
The surge in open interest and heavy trading in both call and put options ahead of the 27 October expiry highlight a nuanced market outlook. The concentration of call option contracts at ₹11,000 strike, representing a 7.7% premium over the current price, indicates bullish bets on a near-term recovery. Conversely, the large put option volumes at strikes above the current price reflect hedging or bearish positioning, signalling caution.
This derivatives activity, combined with the stock’s price underperformance, suggests investors are actively managing risk amid sectoral challenges such as slowing demand and input cost inflation. The interplay between these forces will likely influence Bajaj Auto’s price volatility in the coming weeks.

4. Derivatives Activity Highlights Caution: Heavy call and put option volumes and a 19% rise in open interest point to hedging and speculative positioning ahead of the October expiry, indicating uncertainty.

Conclusion
Bajaj Auto Ltd’s week was dominated by sharp declines driven by sectoral weakness, broader market caution, and complex derivatives positioning. The stock’s 11.20% fall contrasted with the Sensex’s more moderate 3.20% decline, underscoring company-specific challenges. Elevated trading volumes and open interest increases highlight active investor engagement and hedging amid uncertainty.
While short-term technical indicators and price action suggest caution, the stock’s position above its 200-day moving average and strong institutional participation provide some support. The mixed signals from options markets ahead of the 27 October expiry warrant close monitoring, as they may presage increased volatility or a potential directional shift.
Investors should remain attentive to sector developments and price action around key support levels near Rs.10,200 to Rs.10,500. Bajaj Auto’s large-cap stature and fundamental strengths continue to underpin its medium-term outlook, despite the recent volatility and downgrade in analyst sentiment.
