Hindustan Zinc Sees Robust Call Option Activity Amidst Steady Price Gains

Call Option Activity Highlights

Among the most actively traded call options on the National Stock Exchange, Hindustan Zinc's contracts expiring on 30 December 2025 have drawn considerable investor interest. The strike prices of ₹640 and ₹650 have seen the highest volumes, with 11,236 and 11,722 contracts traded respectively. This activity corresponds to a turnover of approximately ₹1154.8 lakhs for the ₹640 strike and ₹732.3 lakhs for the ₹650 strike, indicating substantial liquidity and market participation.

Open interest figures further underline the sustained interest in these strike prices, with 3,296 contracts outstanding at ₹640 and 5,492 contracts at ₹650. The underlying stock value at the time of this activity was ₹639.5, placing these strike prices close to the current market level and suggesting a focus on near-the-money options.

Price Performance and Market Context

Hindustan Zinc's stock price has been on a steady trajectory, hitting a new 52-week high of ₹646.5 on the day of this report. The stock opened with a gap up of 3.22% and touched an intraday high that represented a 3.46% increase from the previous close. Over the past four trading sessions, the stock has recorded cumulative returns of 8.31%, reflecting a sustained bullish trend.

The stock is trading above its key moving averages, including the 5-day, 20-day, 50-day, 100-day, and 200-day averages, which often signals positive technical momentum. This performance aligns with the broader Non-Ferrous Metals sector, which has gained 2.32% on the day, indicating sectoral support for the stock's price movement.

Investor Participation and Liquidity Considerations

Despite the positive price action, investor participation as measured by delivery volume has shown a decline. On 24 December, delivery volume stood at 38.83 lakh shares, representing a 12% reduction compared to the five-day average delivery volume. This suggests a cautious approach among some investors, possibly reflecting profit booking or repositioning ahead of the year-end.

Liquidity remains adequate for sizeable trades, with the stock's average traded value supporting trade sizes up to ₹15.52 crore based on 2% of the five-day average traded value. This level of liquidity is favourable for institutional and retail investors seeking to enter or exit positions without significant market impact.

Sector and Market Comparison

Hindustan Zinc's one-day return of 2.14% is closely aligned with the Non-Ferrous Metals sector gain of 2.34%, while the broader Sensex index experienced a marginal decline of 0.19%. This relative outperformance within the sector highlights the stock's resilience amid mixed market conditions.

The company operates within the Non-Ferrous Metals industry and holds a large-cap market capitalisation of approximately ₹2,64,019 crore, underscoring its significance in the sector and the Indian equity market at large.

Expiry Patterns and Bullish Positioning

The concentration of call option activity at strike prices near the current market value, particularly at ₹640 and ₹650, suggests a market expectation of continued upward price movement or at least a willingness to hedge against such a scenario. The expiry date of 30 December 2025 is imminent, which often leads to increased trading volumes as market participants adjust their positions ahead of contract settlement.

Open interest data indicates that the ₹650 strike has a higher number of outstanding contracts compared to ₹640, which may reflect a stronger conviction or hedging interest at this level. The substantial turnover and open interest at these strikes highlight the stock's attractiveness for options traders seeking exposure to potential price appreciation or volatility plays.

Technical Indicators and Market Sentiment

Trading above all major moving averages is a technical signal that often attracts momentum-driven investors. Hindustan Zinc's alignment with this pattern, combined with its recent four-day gain streak, points to a positive market sentiment. However, the slight decline in delivery volumes suggests some investors may be cautious, possibly awaiting further confirmation of the trend or external market cues.

Sectoral gains in Non-Ferrous Metals provide additional support, as commodity prices and industrial demand factors influence the performance of companies like Hindustan Zinc. The stock's ability to keep pace with sector gains while outperforming the broader market index reinforces its standing as a key player in this space.

Outlook for Investors

For investors monitoring derivatives activity as a gauge of market sentiment, the robust call option volumes and open interest near current price levels offer insights into prevailing expectations. The liquidity and turnover figures suggest that the stock remains a preferred choice for both hedging and speculative strategies.

While the stock's recent price action and technical positioning are favourable, the mixed signals from delivery volumes and broader market conditions warrant a measured approach. Investors may consider monitoring upcoming market developments and sector trends to better assess the sustainability of the current momentum.

Summary

Hindustan Zinc's derivatives market activity, particularly in call options expiring at the end of December 2025, reflects a concentrated interest around strike prices close to the prevailing stock price. The underlying stock's recent gains, supported by sectoral strength and technical indicators, complement this activity. However, a slight moderation in investor participation through delivery volumes suggests a nuanced market outlook. Overall, the stock remains a focal point for traders and investors within the Non-Ferrous Metals sector as the year draws to a close.
