Hindustan Zinc Ltd Sees Sharp Open Interest Surge Amidst Steady Price Gains

Open Interest and Volume Dynamics

The latest data reveals that Hindustan Zinc’s open interest increased by 8,970 contracts from the previous 51,814, marking a substantial 17.31% rise. This surge in open interest is complemented by a volume of 63,326 contracts, indicating strong participation from traders and investors in the derivatives market. The futures value stood at approximately ₹58,400.93 lakhs, while the options segment exhibited an enormous notional value of ₹42,887.41 crores, underscoring the stock’s liquidity and active trading interest.

Such a pronounced increase in open interest, coupled with high volumes, often suggests that new positions are being established rather than existing ones being squared off. This can be interpreted as a sign of conviction among market participants regarding the stock’s near-term prospects.

Price Performance and Moving Averages

Hindustan Zinc has outperformed its sector peers marginally, gaining 2.72% on the day and outperforming the non-ferrous metals sector by 0.31%. The stock has been on a four-day consecutive gain streak, delivering a cumulative return of 5.18% during this period. Intraday, the stock touched a high of ₹621.3, representing a 4.01% rise from its previous close.

Technically, the stock is trading above its 5-day, 100-day, and 200-day moving averages, signalling underlying strength and a positive medium- to long-term trend. However, it remains below its 20-day and 50-day moving averages, indicating some near-term resistance and potential consolidation before a sustained breakout.

Sector and Market Context

The non-ferrous metals sector has gained 2.75% on the day, slightly ahead of Hindustan Zinc’s performance. The broader Sensex index rose by a modest 0.18%, highlighting the stock’s relative strength within its industry. Despite this, investor participation in terms of delivery volume has declined, with a 23.06% drop against the five-day average, suggesting that short-term traders may be dominating the price action rather than long-term holders.

Liquidity remains adequate, with the stock’s traded value supporting a trade size of approximately ₹6.97 crores based on 2% of the five-day average traded value. This ensures that market participants can enter and exit positions without significant price impact.

Market Positioning and Directional Bets

The sharp rise in open interest alongside increasing volumes suggests that market participants are positioning for a directional move. Given the stock’s recent price appreciation and technical setup, the bias appears to be bullish. Traders may be initiating fresh long positions, anticipating further upside driven by favourable fundamentals and sector tailwinds.

Hindustan Zinc’s underlying value currently stands at ₹613, with the stock trading near its recent highs. The combination of rising open interest and price gains typically indicates that buyers are confident and willing to commit capital, expecting the rally to continue. This is further supported by the stock’s mojo score of 64.0, which, while downgraded from a previous Buy rating to Hold on 13 Feb 2026, still reflects a stable outlook with moderate upside potential.

Investors should note that the downgrade to Hold was influenced by valuation concerns and near-term resistance levels, but the stock’s large market capitalisation of ₹2,59,519.09 crores and strong sector fundamentals provide a solid base for sustained performance.

Risks and Considerations

Despite the positive signals, some caution is warranted. The decline in delivery volumes suggests that long-term investor participation has waned, which could lead to increased volatility if short-term traders decide to exit positions abruptly. Additionally, the stock’s position below the 20-day and 50-day moving averages indicates that it may face resistance in the near term, potentially limiting upside momentum.

Furthermore, the non-ferrous metals sector is sensitive to global commodity price fluctuations, currency movements, and regulatory changes, all of which could impact Hindustan Zinc’s earnings and stock performance.

Outlook and Investor Takeaways

Hindustan Zinc’s recent surge in open interest and volume, combined with its price strength, suggests a constructive near-term outlook. The stock’s mojo grade of Hold reflects a balanced view, acknowledging both the upside potential and the risks posed by valuation and technical resistance.

For investors, the key will be to monitor whether the stock can sustain its momentum above the 20-day and 50-day moving averages, which would confirm a more robust uptrend. Additionally, watching delivery volumes and open interest trends will provide insights into the quality of the rally and the commitment of long-term investors.

Given the stock’s large-cap status and sector leadership, it remains a core holding for those seeking exposure to the non-ferrous metals space, albeit with a cautious stance until clearer breakout signals emerge.
