Hindustan Zinc Sees Heavy Put Option Activity Amid Bullish Price Momentum

Put Option Activity Highlights

On 12 December 2025, Hindustan Zinc recorded the highest number of put contracts traded among its peers, with 5,853 contracts exchanged at the strike price of Rs 540. This activity generated a turnover of approximately Rs 885.49 lakhs, reflecting substantial investor interest in downside protection or speculative bearish bets ahead of the December expiry. The open interest stood at 1,880 contracts, indicating a sizeable outstanding position that could influence price dynamics as expiry approaches.

The underlying stock price at the time was Rs 548.85, slightly above the put strike price, suggesting that these options may be used either as hedges by long holders or as speculative instruments anticipating a price correction. The concentration of put options at Rs 540, close to the current market price, highlights a critical support level watched by market participants.

Price Performance and Market Context

Contrary to the heavy put option activity, Hindustan Zinc’s share price has shown resilience. The stock touched an intraday high of Rs 549, marking a 5.04% rise on the day and setting a fresh 52-week peak. Over the last four trading sessions, the stock has delivered cumulative returns of 11.91%, outpacing the Non-Ferrous Metals sector’s gain of 4.74% and the broader Sensex’s 0.43% increase on the same day.

Hindustan Zinc’s price currently trades above all key moving averages, including the 5-day, 20-day, 50-day, 100-day, and 200-day averages, underscoring a sustained upward trend. This technical positioning often attracts momentum-driven buying, which may partly explain the divergence between option market sentiment and spot price action.

Investor Participation and Liquidity

Investor engagement in Hindustan Zinc has intensified, with delivery volumes reaching 74.18 lakh shares on 11 December 2025. This figure represents a near 193% rise compared to the five-day average delivery volume, signalling heightened conviction among participants. The stock’s liquidity profile supports sizeable trades, with an estimated tradable value of Rs 10.9 crore based on 2% of the five-day average traded value, facilitating efficient execution for institutional and retail investors alike.

Sector and Market Capitalisation Overview

Hindustan Zinc operates within the Non-Ferrous Metals industry, a sector that has seen a 4.74% gain recently, reflecting broader commodity price trends and industrial demand. The company’s market capitalisation stands at Rs 2,27,428 crore, categorising it as a large-cap stock with significant influence in its segment.

The stock’s 1-day return of 5.09% surpasses both the sector’s 4.70% and the Sensex’s 0.43%, indicating relative strength. This outperformance, coupled with the stock’s technical positioning, suggests that market participants are factoring in positive fundamentals or near-term catalysts despite the notable put option interest.

Interpreting Put Option Interest in Context

Heavy put option activity often signals investor caution or hedging strategies, especially when concentrated near the current price level. In Hindustan Zinc’s case, the Rs 540 strike price for puts expiring on 30 December 2025 is just below the prevailing market price, which may indicate that investors are seeking protection against a potential pullback after recent gains.

Alternatively, some market participants might be positioning for a volatility event or using puts as a speculative tool to capitalise on expected price declines. The open interest of 1,880 contracts suggests that these positions are not merely transient but could influence price behaviour as expiry nears.

Given the stock’s upward momentum and strong delivery volumes, the coexistence of bullish price action and bearish option positioning reflects a nuanced market outlook. Investors may be balancing optimism about the company’s prospects with prudence against short-term risks such as commodity price fluctuations or macroeconomic factors impacting the metals sector.

Expiry Patterns and Market Implications

The 30 December 2025 expiry date for the put options is significant as it coincides with the end of the calendar year, a period often marked by portfolio rebalancing and strategic positioning by institutional investors. The concentration of put contracts at the Rs 540 strike price suggests that this level is viewed as a key threshold for risk management.

As expiry approaches, the interplay between open interest and spot price will be closely monitored. Should the stock price remain above Rs 540, many of these puts may expire worthless, potentially reducing downside pressure. Conversely, a decline below this level could trigger increased option exercise or unwinding, adding volatility to the stock.

Conclusion: A Complex Market Landscape

Hindustan Zinc’s current market activity presents a compelling case of contrasting signals. On one hand, the stock’s price trajectory and volume metrics point to sustained investor confidence and sectoral strength. On the other, the heavy put option activity near the money highlights a layer of caution or hedging that cannot be overlooked.

For investors and market watchers, this duality underscores the importance of analysing both the derivatives market and underlying price action to gauge sentiment accurately. The coming weeks, leading up to the December expiry, will be critical in revealing whether the put option interest translates into actual price corrections or remains a strategic hedge amid ongoing bullish momentum.

Overall, Hindustan Zinc remains a focal point within the Non-Ferrous Metals sector, with its large-cap stature and active options market making it a key stock to watch for both fundamental and technical developments.
