The strike price of ₹13 attracted the highest number of contracts, with 8,537 contracts traded on the day. This activity generated a turnover of approximately ₹854.25 lakhs, reflecting substantial liquidity and investor engagement in this segment.
Open interest at this strike price stood at 5,942 contracts, indicating a sustained interest in call options at this level.

Sectoral and Broader Market Considerations
The Telecom - Services sector has shown a 1.01% gain on the day, outperforming Vodafone Idea's 0.62% rise. This relative performance may be influenced by company-specific factors or broader sector dynamics such as regulatory developments, competitive pressures, or shifts in consumer demand.
Meanwhile, the Sensex index's decline of 0.46% on the same day highlights a mixed market environment where sectoral and individual stock performances diverge. Vodafone Idea's ability to trade above multiple moving averages suggests some underlying strength despite the broader market headwinds.
Outlook for Option Traders
For investors and traders focusing on derivatives, Vodafone Idea's active call option market presents opportunities to engage with the stock's potential price movements. The significant open interest and turnover at the ₹13 strike price indicate that many market participants are positioning for a scenario where the stock price approaches or surpasses this level by expiry.
However, given the current underlying price of ₹11.42, this would require a notable price appreciation within the remaining days of the December expiry cycle. Traders should consider the stock's liquidity, volatility, and sector trends when evaluating their option strategies.
Conclusion
Vodafone Idea Ltd. is currently a focal point in the call options market, with substantial activity centred on the ₹13 strike price for the 30 December 2025 expiry. The stock's trading above key moving averages and rising delivery volumes suggest a nuanced market sentiment that blends cautious optimism with the realities of sectoral challenges.
Investors and market watchers will be closely observing Vodafone Idea's price trajectory in the coming weeks as the expiry date approaches, with option market data providing valuable insights into prevailing expectations and positioning.
