Put Option Activity Highlights
Data from the derivatives market reveals that Kotak Mahindra Bank Ltd witnessed 8,169 put contracts traded with a strike price of ₹2,160, expiring on 30 December 2025. The turnover for these contracts reached ₹684.89 lakhs, while open interest stood at 2,428 contracts. This level of activity places Kotak Mahindra Bank at the forefront of put option trading volumes, indicating a significant focus on downside protection or speculative bearish positioning among market participants.
The underlying stock value at the time of this activity was ₹2,187.40, which is slightly above the put strike price. This proximity suggests that traders are closely monitoring the stock’s near-term price movements and are possibly preparing for volatility or a correction in the coming weeks.
Stock Performance and Market Context
Kotak Mahindra Bank’s stock performance on the day of this options activity showed a gain of 2.96%, outperforming its private sector banking peers by 2.21%. The stock has recorded consecutive gains over the last two sessions, accumulating a return of 2.94% during this period. Intraday, the share price touched a high of ₹2,205, representing a 3.55% increase from the previous close.
Technical indicators also reflect a positive trend, with the stock trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. This suggests a sustained upward momentum in the medium to long term. However, delivery volumes on 10 December 2025 showed a decline of 14.37% compared to the five-day average, signalling a reduction in investor participation despite the price gains.
Liquidity remains robust, with the stock’s traded value supporting trade sizes up to ₹11.37 crores based on 2% of the five-day average traded value. This level of liquidity is conducive to active trading and options market activity.

Implications of Put Option Concentration
The concentration of put option activity at the ₹2,160 strike price, which is marginally below the current market price, suggests that investors are either hedging existing long positions or speculating on a potential price decline. Put options provide the right to sell shares at the strike price, offering protection against downside risk or enabling profit from falling prices.
Open interest of 2,428 contracts at this strike indicates that a sizeable number of traders are maintaining these positions as the expiry date approaches. This could reflect a cautious stance amid broader market uncertainties or sector-specific concerns within the private banking space.
Sector and Market Comparison
Within the private sector banking industry, Kotak Mahindra Bank’s 1-day return of 2.99% notably outpaces the sector’s 0.67% gain and the Sensex’s 0.48% rise on the same day. This relative strength contrasts with the heavy put option activity, highlighting a divergence between the stock’s price action and options market sentiment.
Such divergence may indicate that while the stock is currently performing well, some investors are preparing for potential volatility or a pullback. This dynamic is common in liquid large-cap stocks where sophisticated market participants use options to manage risk or express nuanced views on future price movements.

Outlook and Investor Considerations
Investors observing Kotak Mahindra Bank’s options market activity should consider the implications of the concentrated put option interest. While the stock’s recent price trajectory and technical indicators suggest strength, the options data points to a degree of caution or hedging among market participants.
Given the expiry date of 30 December 2025, the coming weeks will be critical in determining whether the stock sustains its upward momentum or experiences increased volatility. Market participants may wish to monitor open interest changes, strike price concentrations, and delivery volumes to gauge evolving sentiment.
Additionally, the broader economic environment, sectoral developments, and regulatory factors impacting private sector banks will continue to influence Kotak Mahindra Bank’s price dynamics and options market behaviour.
Summary
Kotak Mahindra Bank’s prominence in put option trading ahead of the December expiry highlights a complex market landscape where bullish price action coexists with significant bearish hedging. The stock’s large-cap status, liquidity, and sector leadership underpin active derivatives interest, making it a focal point for investors seeking to manage risk or capitalise on potential price movements.
Careful analysis of both the stock’s fundamentals and options market data will be essential for informed decision-making in the weeks ahead.
