Hindustan Zinc Sees Robust Call Option Activity Amid Sector Gains

Call Option Activity Highlights

On 22 December 2025, Hindustan Zinc Ltd (HINDZINC) recorded notable call option volumes for the expiry dated 30 December 2025. The strike price of Rs 600 attracted the highest number of contracts traded, with 7,756 contracts exchanging hands. This activity generated a turnover of approximately Rs 1,324.45 lakhs, signalling strong interest from market participants in this price band.

Open interest at this strike price stood at 3,551 contracts, indicating a substantial build-up of positions that may influence price movements as expiry approaches. The underlying stock value was Rs 604.55 at the time, slightly above the Rs 600 strike, suggesting that traders are positioning for continued upward momentum.

Price Movement and Market Context

Hindustan Zinc’s stock price reached an intraday high of Rs 606.7, marking a fresh 52-week peak. The stock opened with a gap up of 2.12% and closed with a day’s return of 2.65%, closely mirroring the sector’s gain of 2.42% and outperforming the Sensex’s 0.60% rise on the same day. This performance underscores the stock’s relative strength within the non-ferrous metals sector.

Technical indicators show that Hindustan Zinc is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, reinforcing the positive technical momentum. Such alignment across multiple timeframes often attracts further investor interest, particularly from traders relying on technical analysis.

Sector and Industry Overview

The non-ferrous metals sector, to which Hindustan Zinc belongs, has demonstrated resilience with a 1-day return of 2.42%. This sector-wide performance provides a supportive backdrop for Hindustan Zinc’s price action and option market activity. The company’s market capitalisation stands at Rs 2,55,357.15 crores, categorising it firmly as a large-cap stock with significant liquidity and institutional interest.

Despite a noted decline in delivery volume to 38.67 lakh shares on 19 December, which is 32.35% below the 5-day average, the stock maintains sufficient liquidity. The average traded value supports a trade size of approximately Rs 18.61 crores, ensuring that market participants can execute sizeable transactions without undue price impact.

Investor Positioning and Expiry Dynamics

The concentration of call option contracts at the Rs 600 strike price, coupled with the underlying stock price hovering just above this level, suggests a bullish sentiment among traders. This positioning may reflect expectations of further price appreciation before the 30 December expiry.

Open interest data indicates that a sizeable number of traders are holding onto these call options, potentially anticipating a breakout or sustained rally. The expiry date being just over a week away adds urgency to these positions, as traders seek to capitalise on short-term price movements.

Technical and Fundamental Considerations

From a technical perspective, the stock’s trading above all major moving averages signals a strong trend. This technical backdrop often encourages speculative activity in options markets, as traders look to leverage price swings with limited capital outlay.

Fundamentally, Hindustan Zinc’s standing as a large-cap player in the non-ferrous metals industry provides a degree of stability and investor confidence. The company’s market capitalisation and liquidity metrics support active trading and institutional participation, which can amplify price trends and option market interest.

Outlook and Market Implications

As Hindustan Zinc approaches the December expiry, the elevated call option activity at the Rs 600 strike price will be closely monitored by market participants. The stock’s recent price behaviour and sector alignment provide a context for this options interest, which may influence volatility and trading volumes in the near term.

Investors and traders should consider the interplay of technical signals, liquidity conditions, and sector dynamics when analysing Hindustan Zinc’s market movements. The options market data offers a window into market expectations and risk appetite, which can be valuable for informed decision-making.

Overall, Hindustan Zinc’s current market environment reflects a blend of technical strength and active investor engagement, particularly in the derivatives segment, underscoring its prominence within the non-ferrous metals sector.
