Hindustan Zinc Sees Heavy Put Option Activity Ahead of December Expiry

Put Option Activity Highlights

Data from the derivatives market reveals that Hindustan Zinc Ltd (HINDZINC) recorded 4,667 put option contracts traded with a strike price of ₹580, set to expire on 30 December 2025. This volume represents a significant turnover of ₹65.4 crores (654.03 lakhs), accompanied by an open interest of 1,502 contracts. The underlying stock price at the time stood at ₹586.75, just 1.36% shy of its 52-week high of ₹594.35.

The concentration of put options at this strike price suggests that market participants are positioning for potential downside risk or are employing protective hedges against the stock’s current valuation. The expiry date being less than two weeks away adds urgency to these trades, as investors adjust their portfolios ahead of the settlement.

Stock Price and Market Context

Hindustan Zinc’s share price has shown resilience, trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a generally positive trend over multiple timeframes. However, the stock experienced a reversal after two consecutive days of gains, with an intraday low of ₹578.05, marking a 2.38% dip on the day. The day’s closing price reflected a decline of 1.16%, slightly underperforming the sector’s 0.96% fall, while the broader Sensex index recorded a 0.61% gain.

Investor participation appears to be moderating, with delivery volumes on 18 December falling by 11.6% compared to the five-day average, registering at 54.09 lakh shares. Despite this, liquidity remains adequate, with the stock’s traded value supporting sizeable transactions up to ₹25.44 crores based on 2% of the five-day average traded value.

Implications of Put Option Concentration

The heavy put option activity at the ₹580 strike price, slightly below the current market price, may indicate that traders are anticipating a potential pullback or are seeking downside protection. Put options serve as a hedge against falling prices, and the elevated open interest suggests that a sizeable number of investors are either speculating on declines or safeguarding existing long positions.

Given the proximity to the 52-week high, this pattern could reflect a cautious stance amid recent volatility. The stock’s fall after two days of gains and the intraday low near the put strike price reinforce the notion that market participants are preparing for possible price corrections in the near term.

Sector and Market Comparison

Hindustan Zinc operates within the Non-Ferrous Metals industry, a sector that has experienced mixed performance in recent sessions. The stock’s 1.16% decline on the day slightly outpaced the sector’s 0.96% fall, while the Sensex index advanced by 0.61%. This divergence highlights the stock-specific factors influencing investor behaviour, including the derivatives market positioning.

With a market capitalisation of approximately ₹2,47,308 crores, Hindustan Zinc is classified as a large-cap stock, attracting significant institutional and retail interest. The liquidity metrics support active trading, which is essential for the smooth functioning of options markets and effective risk management.

Expiry Patterns and Investor Behaviour

The December 30 expiry date for the put options is a critical juncture for traders. As expiry approaches, open interest levels and trading volumes often provide insights into market sentiment and potential price movements. The concentration of put contracts at ₹580 suggests that investors are closely monitoring this level as a key support or trigger point.

Options expiry can lead to increased volatility as positions are squared off or rolled over. The current data implies that market participants are actively managing risk, possibly in response to recent price fluctuations and sector dynamics.

Outlook for Hindustan Zinc

While Hindustan Zinc remains close to its 52-week high, the derivatives market activity points to a nuanced outlook. The presence of substantial put option interest at a strike price just below the current market value indicates a degree of caution among investors. This may reflect expectations of short-term price consolidation or correction, balanced against the stock’s longer-term strength as evidenced by its position above key moving averages.

Investors and traders should monitor the evolving open interest and price action as the December expiry nears, as these factors will provide further clarity on market positioning and potential directional shifts.

Conclusion

Hindustan Zinc’s prominence in put option trading ahead of the December expiry highlights the importance of derivatives as a tool for hedging and expressing market views. The significant volume and open interest at the ₹580 strike price underscore a cautious stance among investors despite the stock’s proximity to its yearly peak. As expiry approaches, the interplay between spot price movements and options positioning will be critical for understanding the stock’s near-term trajectory within the Non-Ferrous Metals sector.
