NMDC Ltd Sees Significant Open Interest Surge Amid Mixed Market Signals

Open Interest and Volume Dynamics

The latest data shows NMDC’s open interest rising sharply to 93,198 contracts, up 15.32% from the previous 80,820. This increase of 12,378 contracts indicates a substantial build-up of positions in the futures and options market. Concurrently, the volume traded stood at 47,282 contracts, reflecting robust participation but not an overwhelming surge relative to the OI growth.

The futures value associated with these contracts is approximately ₹1,86,266.60 lakhs, while the options segment commands a staggering ₹7,18,198.02 lakhs in notional value, culminating in a total derivatives market value of ₹1,87,219.44 lakhs. This scale of activity underscores the stock’s prominence among derivatives traders and the significant capital at play.

Price Performance and Moving Averages

On the price front, NMDC has outperformed its sector by 0.49% today, delivering a 0.24% gain against a sector decline of 0.44% and a Sensex drop of 0.85%. The stock has recorded gains over the past two consecutive sessions, accumulating a 1.46% return in this period. Notably, the current price of ₹80 remains above the 100-day and 200-day moving averages, signalling a longer-term bullish trend. However, it trades below the 5-day, 20-day, and 50-day averages, suggesting some short-term consolidation or resistance.

Investor participation appears to be waning, with delivery volume on 18 Feb falling sharply by 53.31% to 57.1 lakh shares compared to the five-day average. This decline in delivery volume may indicate reduced conviction among long-term holders, even as derivatives activity intensifies.

Market Positioning and Directional Bets

The surge in open interest, coupled with steady volume, suggests that market participants are actively repositioning themselves in NMDC derivatives. The increase in OI often reflects fresh capital entering the market, either through new long or short positions. Given the stock’s recent price gains and its standing above key long-term moving averages, it is plausible that a significant portion of this OI increase represents bullish bets.

However, the fact that the stock trades below its short-term moving averages and the decline in delivery volumes introduces an element of caution. Some traders may be hedging existing positions or speculating on potential near-term volatility. The high dividend yield of 7.24% at the current price adds an additional layer of complexity, as income-focused investors might prefer holding the stock outright rather than engaging in derivatives.

Liquidity and Market Capitalisation Context

NMDC’s market capitalisation stands at ₹70,580.71 crores, categorising it as a mid-cap stock within the Minerals & Mining sector. The stock’s liquidity is adequate for sizeable trades, with the average traded value over five days supporting trade sizes up to ₹3.61 crores based on 2% of average volume. This liquidity profile facilitates active derivatives trading without excessive slippage, attracting institutional and retail participants alike.

The company’s Mojo Score currently sits at 75.0, with a Buy grade assigned on 13 Feb 2026, a slight downgrade from a previous Strong Buy rating. This adjustment reflects a nuanced view of the stock’s near-term prospects, balancing solid fundamentals against emerging technical resistance and market uncertainties.

Implications for Investors and Traders

The current derivatives activity in NMDC suggests a market bracing for potential directional moves. The sizeable increase in open interest signals that traders are positioning for volatility, possibly anticipating a breakout or a correction depending on broader market cues and sectoral developments.

Investors should monitor the interplay between price action and open interest closely. A sustained rise in price accompanied by increasing OI would confirm bullish momentum, while a price decline with rising OI might indicate growing bearish sentiment or short-covering dynamics. The recent downgrade from Strong Buy to Buy by MarketsMOJO reflects this cautious stance, urging investors to weigh fundamentals against technical signals carefully.

Given the stock’s attractive dividend yield and mid-cap status, long-term investors may find value in accumulating shares during short-term dips, while traders could exploit the heightened derivatives activity to capitalise on volatility through strategic option plays or futures positions.

Sector and Market Outlook

The Minerals & Mining sector has faced mixed headwinds recently, including fluctuating commodity prices and regulatory developments. NMDC’s ability to outperform its sector on a day when the broader market and Sensex declined is a positive indicator of relative strength. However, the sector’s overall volatility necessitates a prudent approach to trading and investment decisions.

Market participants should also consider macroeconomic factors such as global demand for minerals, infrastructure spending, and government policies impacting mining operations. These elements will influence NMDC’s price trajectory and derivatives market behaviour in the coming weeks.

Conclusion

NMDC Ltd’s sharp rise in open interest amid modest price gains and mixed volume signals highlights an active and evolving market landscape. The stock’s derivatives segment is witnessing increased positioning, reflecting both bullish and cautious sentiments. Investors and traders should adopt a balanced approach, leveraging comprehensive research and technical analysis to navigate the complexities of this mid-cap Minerals & Mining stock.

With a solid market capitalisation, decent liquidity, and a high dividend yield, NMDC remains an attractive proposition for a range of market participants. However, the recent downgrade in rating and short-term technical resistance warrant careful monitoring of price and open interest trends to capitalise on emerging opportunities effectively.
