Open Interest Spike and Volume Dynamics
On 22 Jan 2026, Adani Ports recorded an open interest (OI) of 1,07,316 contracts in its derivatives, marking a substantial increase of 19,908 contracts or 22.78% compared to the previous OI of 87,408. This sharp rise in OI is accompanied by a futures volume of 86,465 contracts, indicating strong trading activity. The futures value stood at ₹2,62,377 lakhs, while the options segment exhibited an even larger notional value of ₹32,285.7 crores, underscoring the stock's prominence in the derivatives market.
The underlying stock price closed at ₹1,408, having touched an intraday high of ₹1,421.7, a 3.13% gain on the day. This price action, combined with the OI surge, suggests that market participants are positioning for further upside or volatility in the near term.
Market Positioning and Directional Bets
The increase in open interest alongside rising volumes typically signals fresh capital entering the market rather than existing positions being squared off. In Adani Ports’ case, the 22.78% OI growth coupled with a 2.63% day gain and outperformance relative to the Transport Infrastructure sector (which gained 2.47%) and Sensex (0.48%) points to bullish positioning by traders.
Moreover, the stock has recorded gains for two consecutive sessions, delivering a cumulative return of 3.58%, which may have encouraged momentum traders to increase their exposure. The delivery volume on 21 Jan surged by 54.11% to 10.89 lakh shares compared to the five-day average, indicating strong investor participation and conviction in the underlying equity.
Technical Context and Moving Averages
From a technical standpoint, Adani Ports is trading above its 5-day and 200-day moving averages, which often act as short-term and long-term support levels respectively. However, it remains below the 20-day, 50-day, and 100-day moving averages, suggesting some resistance in the medium term. This mixed technical picture may be contributing to the cautious but optimistic stance among derivatives traders, who appear to be positioning for a breakout while managing risk.

Investor Sentiment and Market Cap Considerations
Adani Ports commands a large market capitalisation of ₹3,26,010.21 crores, categorising it firmly as a large-cap stock within the Transport Infrastructure sector. The stock’s Mojo Score currently stands at 57.0, reflecting a Hold rating, an upgrade from its previous Sell grade as of 8 Sep 2025. This improvement in rating indicates a more favourable outlook based on fundamental and technical parameters.
Liquidity remains robust, with the stock’s traded value supporting a trade size of approximately ₹4.58 crores based on 2% of the five-day average traded value. Such liquidity is conducive to active derivatives trading and allows institutional players to build or unwind sizeable positions without significant price impact.
Sectoral and Broader Market Context
The Transport Infrastructure sector has gained 2.73% on the day, slightly outperforming the Sensex’s 0.48% rise. Adani Ports’ outperformance by 0.58% relative to its sector peers highlights its relative strength and attractiveness to investors amid a generally positive market environment. This sectoral momentum may be reinforcing the bullish sentiment seen in the derivatives market.
Given the strategic importance of ports and special economic zones in India’s trade and logistics ecosystem, the stock’s performance is often viewed as a barometer of broader economic activity. The recent surge in open interest could be interpreted as market participants anticipating favourable developments or policy support in the near term.
Risks and Cautionary Notes
Despite the positive signals, investors should remain cautious as the stock trades below several key moving averages, which may act as resistance and cap upside in the short term. Additionally, the derivatives market can be prone to rapid shifts in sentiment, especially in large-cap stocks with significant institutional participation.
Market participants should monitor open interest trends closely in the coming sessions to confirm whether the current surge translates into sustained directional moves or if it represents short-term speculative positioning. Volatility could increase as expiry approaches, necessitating prudent risk management.

Conclusion: Renewed Interest Signals Potential Upside
The recent surge in open interest and volume in Adani Ports & Special Economic Zone Ltd’s derivatives market reflects a renewed investor interest and a possible shift towards bullish positioning. Supported by strong delivery volumes, outperformance relative to sector and benchmark indices, and an upgraded Mojo rating, the stock appears poised for further attention from traders and investors alike.
However, the mixed technical signals and resistance from medium-term moving averages suggest that caution is warranted. Market participants should watch for confirmation of sustained trends in open interest and price action before committing to significant directional bets. Overall, the data points to a stock that is regaining favour but still requires careful analysis amid evolving market conditions.
