Open Interest and Volume Dynamics
On 20 Jan 2026, Dalmia Bharat's open interest in derivatives rose sharply by 1,633 contracts, an 11.31% increase from the previous day's 14,441 to 16,074. This rise in OI was accompanied by a robust volume of 19,037 contracts, indicating heightened trading activity and fresh positions being established rather than merely unwinding existing ones. The futures segment alone accounted for a value of approximately ₹22,554.29 lakhs, while options contributed a staggering ₹11,631.23 crores, underscoring the significant interest in both futures and options instruments.
The underlying stock price closed at ₹2,210, having touched an intraday high of ₹2,212.90, marking a 2.59% gain on the day. This price movement outpaced the Cement sector’s modest 0.18% rise and contrasted with the Sensex’s 0.37% decline, highlighting Dalmia Bharat’s relative strength in a mixed market environment.
Market Positioning and Investor Sentiment
The surge in open interest alongside rising volumes suggests that market participants are actively positioning themselves for a potential upward move in Dalmia Bharat’s stock. The stock’s trading above all key moving averages—5-day, 20-day, 50-day, 100-day, and 200-day—further reinforces a bullish technical setup. Additionally, delivery volumes on 19 Jan rose by 36% compared to the five-day average, with 2.73 lakh shares changing hands in delivery, signalling genuine investor participation rather than speculative intraday trading.
Despite this positive momentum, it is important to note that MarketsMOJO has downgraded Dalmia Bharat’s Mojo Grade from Hold to Sell as of 22 Dec 2025, reflecting concerns over valuation or near-term fundamentals. The Mojo Score currently stands at 37.0, indicating a cautious stance. The company’s market capitalisation is ₹41,506.47 crores, categorising it as a mid-cap stock with a Market Cap Grade of 2, which may imply moderate liquidity and volatility considerations for investors.

Implications of Rising Open Interest in Derivatives
Open interest is a critical indicator of market sentiment and liquidity in the derivatives market. An increase in OI, especially when accompanied by rising prices and volumes, often signals that new money is flowing into the market, with traders taking fresh positions. For Dalmia Bharat, the 11.31% jump in OI suggests that participants are either building bullish positions through futures contracts or engaging in option strategies that benefit from upward price movements.
Given the substantial option value of over ₹11,631 crores, it is likely that a mix of call buying and put selling is occurring, which typically reflects bullish sentiment. However, the large notional value also indicates that the stock is a focus for hedging and speculative activity, which can increase volatility in the near term.
Technical and Fundamental Outlook
Technically, Dalmia Bharat’s price action is encouraging. The stock’s ability to trade above all major moving averages suggests strong underlying demand and a positive trend reversal after two days of consecutive declines. The intraday high of ₹2,212.90 represents a 2.59% gain, outperforming the sector and broader indices, which may attract momentum traders and institutional investors looking for relative strength plays.
On the fundamental front, the downgrade to a Sell rating by MarketsMOJO reflects caution. The Mojo Score of 37.0 is relatively low, indicating concerns about valuation or earnings growth prospects. Investors should weigh the technical strength and increased market participation against these fundamental reservations.

Investor Considerations and Risk Factors
Investors should approach the recent surge in open interest with a balanced perspective. While the technical indicators and volume patterns point to increased bullish positioning, the fundamental downgrade and moderate Mojo Score suggest underlying risks. The cement sector is subject to cyclical demand fluctuations, input cost pressures, and regulatory changes, all of which can impact earnings and stock performance.
Moreover, the sizeable derivatives activity may lead to heightened volatility, especially around key support and resistance levels. Traders should monitor open interest trends closely, as a sudden drop in OI after a price rise could indicate profit-taking or position unwinding, potentially reversing the current momentum.
Conclusion
Dalmia Bharat Ltd’s recent open interest surge in derivatives, coupled with strong volume and price outperformance, signals renewed investor interest and potential bullish bets on the stock. However, the downgrade to a Sell rating and a modest Mojo Score counsel caution. Market participants should weigh the technical momentum against fundamental concerns and sector dynamics before making investment decisions. The stock’s liquidity and active derivatives market provide ample opportunities for both traders and investors to capitalise on short-term trends while managing risk prudently.
