Bajaj Auto Ltd. Sees Significant Open Interest Surge Amid Mixed Price Action

Open Interest and Volume Dynamics

The open interest (OI) in Bajaj Auto’s futures and options contracts rose sharply from 66,108 to 74,347 contracts, an increase of 8,239 contracts on 1 Feb 2026. This 12.46% jump in OI accompanied a total volume of 110,068 contracts traded, indicating robust participation in the derivatives market. The futures segment alone accounted for a value of approximately ₹61,974 lakhs, while options contracts contributed a staggering ₹75,716 crores in notional value, underscoring the stock’s prominence among derivatives traders.

Such a surge in OI typically suggests fresh positions being established rather than existing ones being squared off. This can be interpreted as increased conviction among market participants, either in anticipation of a directional move or as part of hedging strategies amid volatile conditions.

Price Action and Market Positioning

On the price front, Bajaj Auto’s stock closed lower by 1.91% on the day, underperforming the automobile sector’s decline of 1.80% and the Sensex’s 1.31% fall. The stock’s intraday range was wide, touching a high of ₹9,855 (up 2.68%) and a low of ₹9,175.5 (down 4.4%), reflecting significant volatility. Notably, the weighted average price skewed closer to the day’s low, indicating that heavier volumes traded near the lower price levels, which may signal selling pressure or profit-booking by short-term traders.

Technical indicators show the stock trading above its 50-day, 100-day, and 200-day moving averages, suggesting a longer-term uptrend remains intact. However, it is currently below its 5-day and 20-day moving averages, hinting at short-term weakness or consolidation. Rising delivery volumes, which increased by 15.24% to 1.6 lakh shares on 30 Jan 2026 compared to the five-day average, point to growing investor participation and interest in the underlying equity.

Interpreting the Derivatives Activity

The combination of rising open interest and elevated volumes in Bajaj Auto’s derivatives contracts suggests that traders are actively repositioning. The increase in OI alongside a falling stock price may indicate that some participants are building short positions, betting on further downside or hedging existing long exposures. Conversely, the intraday high and the stock’s position above key moving averages imply that a segment of investors remains optimistic about the stock’s medium-term prospects.

Given the stock’s large market capitalisation of ₹2,72,000 crores and its status as a heavyweight in the automobile sector, such mixed signals in derivatives markets often reflect broader sectoral or macroeconomic uncertainties. Investors may be balancing expectations of demand recovery against concerns over input cost inflation or regulatory changes impacting the two-wheeler and three-wheeler segments.

Mojo Score and Analyst Ratings

Bajaj Auto currently holds a Mojo Score of 67.0, placing it in the ‘Hold’ category, an upgrade from its previous ‘Sell’ rating as of 22 Dec 2025. This reflects an improvement in the company’s fundamentals and market positioning, though caution remains warranted given recent price volatility. The stock’s Market Cap Grade is 1, indicating its classification as a large-cap stock with significant liquidity and institutional interest.

Despite the recent downgrade in short-term momentum, the stock’s fundamentals remain robust, supported by steady demand in the domestic and export markets. However, investors should monitor the evolving derivatives positioning closely, as the surge in open interest could presage increased volatility or a directional breakout in the near term.

Sector and Market Context

The automobile sector has faced headwinds recently, with supply chain disruptions and commodity price inflation impacting margins. Bajaj Auto’s relative underperformance compared to the sector (-0.34% on the day) suggests that investors are selectively cautious. The Sensex’s milder decline of 1.31% indicates that broader market sentiment remains less bearish than the stock’s immediate price action might imply.

Liquidity metrics confirm that Bajaj Auto remains a highly tradable stock, with daily traded value comfortably supporting trade sizes of up to ₹5.92 crores based on 2% of the five-day average traded value. This liquidity is crucial for institutional investors and derivatives traders seeking to establish or unwind sizeable positions without excessive market impact.

Outlook and Investor Considerations

Investors should approach Bajaj Auto with a balanced view. The surge in open interest signals active repositioning and potential for increased volatility, which could present trading opportunities for nimble investors. However, the mixed price signals and recent underperformance relative to sector peers counsel prudence.

Long-term investors may find comfort in the company’s improved Mojo Grade and large-cap status, which provide a degree of stability and institutional backing. Meanwhile, traders should monitor derivatives market data closely for signs of sustained directional bets, particularly if open interest continues to rise alongside volume and price momentum.

In summary, Bajaj Auto’s recent derivatives activity highlights a market at a crossroads, with participants hedging risks and positioning for potential directional moves amid a challenging macroeconomic backdrop. Staying attuned to these dynamics will be key for investors seeking to optimise their exposure to this marquee automobile stock.
