Open Interest and Volume Dynamics
On 29 Jun 2026, NMDC’s open interest (OI) in futures and options contracts rose sharply to 90,502 contracts from the previous 81,417, marking an increase of 9,085 contracts or 11.16%. This surge in OI was accompanied by a futures volume of 31,060 contracts, reflecting active participation in the derivatives market. The total futures value stood at approximately ₹1,15,784.5 lakhs, while the options segment exhibited a substantial notional value of ₹6,557.7 crores, underscoring the stock’s liquidity and interest among derivatives traders.
The underlying stock price closed at ₹85, slightly outperforming the Sensex, which declined by 0.38% on the same day. However, NMDC underperformed its sector benchmark by 0.51%, indicating a nuanced price action despite the increased derivatives activity.
Market Positioning and Directional Bets
The rise in open interest alongside a moderate price increase suggests that market participants are building fresh positions rather than unwinding existing ones. This pattern often indicates a strengthening conviction in the stock’s near-term trend. However, the fact that NMDC’s price remains below its short-term moving averages (5-day, 20-day, and 50-day) but above the longer-term 100-day and 200-day averages points to a consolidation phase rather than a clear breakout.
Investor participation in the cash segment appears to be waning, with delivery volumes on 25 Jun falling by 25.31% compared to the five-day average, signalling reduced conviction among long-term holders. This divergence between derivatives activity and cash market participation may imply that traders are positioning for volatility or directional moves based on upcoming sectoral or macroeconomic developments.

Technical and Fundamental Context
NMDC’s current trading price of ₹85 is supported by a high dividend yield of 4.12%, which remains attractive for income-focused investors. The stock’s liquidity is robust, with the capacity to handle trade sizes of up to ₹5.59 crores based on 2% of the five-day average traded value, ensuring smooth execution for institutional and retail traders alike.
From a technical perspective, the stock’s position above the 100-day and 200-day moving averages indicates a long-term bullish bias. However, the recent price softness relative to the shorter moving averages suggests some near-term resistance and profit-booking pressure. This mixed technical picture aligns with the observed increase in open interest, where both bullish and bearish participants may be active.
Mojo Score and Rating Update
MarketsMOJO assigns NMDC a Mojo Score of 78.0, reflecting a strong buy recommendation, albeit a notch below its previous “Strong Buy” grade as of 15 Jun 2026. This slight downgrade signals a cautious optimism, factoring in recent price action and market volatility. The mid-cap stock’s market capitalisation stands at ₹74,923.87 crores, positioning it well within the Minerals & Mining sector’s competitive landscape.
Implications for Investors and Traders
The surge in open interest combined with stable futures volumes suggests that traders are actively positioning for potential directional moves in NMDC. Given the stock’s mixed technical signals and falling delivery volumes, investors should monitor upcoming sectoral news, commodity price trends, and broader market cues closely.
For long-term investors, the attractive dividend yield and solid fundamentals remain compelling. However, short-term traders may find opportunities in the derivatives market to capitalise on volatility, especially as open interest growth often precedes significant price movements.

Sector and Market Outlook
The Minerals & Mining sector has experienced mixed performance recently, with the sector index gaining 1.03% on the day NMDC’s price rose modestly. This relative underperformance by NMDC may reflect stock-specific factors or profit-taking after recent gains. However, the sector’s overall strength could provide a supportive backdrop for NMDC’s future price appreciation.
Investors should also consider global commodity price trends, regulatory developments, and infrastructure spending plans, which can materially impact mining companies’ earnings and valuations. NMDC’s mid-cap status offers a blend of growth potential and relative stability compared to smaller peers, making it a key stock to watch within the sector.
Conclusion
The recent surge in open interest for NMDC Ltd’s derivatives contracts highlights growing market interest and evolving positioning among traders. While the stock’s price action remains somewhat subdued relative to short-term moving averages, the strong fundamentals, attractive dividend yield, and solid liquidity underpin a positive medium-term outlook.
Investors and traders should remain vigilant to shifts in market sentiment and sector dynamics, using the increased derivatives activity as a barometer for potential price volatility. The current Mojo Grade of “Buy” with a score of 78.0 reflects a balanced view, encouraging participation with appropriate risk management.
