Open Interest Surge and Volume Dynamics
On 19 Jan 2026, Tech Mahindra’s open interest (OI) in derivatives rose sharply by 6,671 contracts, a 13.02% increase from the previous OI of 51,229 to 57,900. This notable rise in OI accompanied a substantial volume of 1,08,886 contracts, indicating strong market activity and fresh positions being established rather than mere unwinding of existing trades. The futures segment alone accounted for a value of approximately ₹1,05,960 lakhs, while options contributed an even larger notional value of ₹1,02,979 crores, culminating in a total derivatives value of ₹1,19,172 lakhs.
The underlying stock price closed at ₹1,721, just 0.99% shy of its 52-week high of ₹1,736.4, underscoring the bullish momentum. Intraday, the stock touched a high of ₹1,734.9, gaining 3.86% on the day and outperforming its sector by 3.98%. This price action, combined with rising OI and volume, suggests that market participants are positioning for further upside.
Market Positioning and Investor Sentiment
The increase in open interest alongside rising prices typically signals fresh buying interest and a strengthening bullish bias. Tech Mahindra’s stock has recorded consecutive gains over the past two sessions, delivering an 8.24% return in this period. The stock is trading above all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — reinforcing the positive technical setup.
Investor participation has also surged, with delivery volumes on 16 Jan reaching 18.08 lakh shares, a 67.91% increase over the five-day average delivery volume. This heightened participation indicates that investors are not merely trading intraday but are committing capital to longer-term holdings, which bodes well for sustained price appreciation.
Liquidity remains robust, with the stock’s average traded value supporting trade sizes up to ₹7.13 crore based on 2% of the five-day average traded value, ensuring that institutional investors can enter or exit positions without significant market impact.

Mojo Score Upgrade and Market Capitalisation Context
Tech Mahindra’s recent upgrade in its Mojo Grade from Hold to Buy on 14 Jan 2026 reflects improved fundamentals and positive market sentiment. The company holds a Mojo Score of 72.0, indicating a favourable outlook based on a blend of financial health, valuation, and technical factors. Its Market Cap Grade remains at 1, confirming its status as a large-cap stock with a market capitalisation of ₹1,68,453 crore.
This upgrade aligns with the observed surge in derivatives activity and price momentum, suggesting that analysts and investors alike are increasingly confident in Tech Mahindra’s growth prospects within the Computers - Software & Consulting sector.
Directional Bets and Potential Implications
The sharp rise in open interest, coupled with rising prices and volume, typically indicates that traders are establishing bullish positions, expecting the stock to continue its upward trajectory. The futures and options data imply that market participants are not only buying outright but also possibly employing strategies such as call buying or bull call spreads to capitalise on anticipated gains.
Given the stock’s proximity to its 52-week high and strong technical indicators, the market positioning suggests a directional bet favouring further appreciation. However, investors should remain mindful of broader market conditions, as the Sensex and sector indices recorded declines of 0.68% and 0.88% respectively on the same day, highlighting some sectoral and market-wide headwinds.
Nonetheless, Tech Mahindra’s outperformance and rising open interest may signal relative strength and potential sector leadership in the near term.

Technical and Fundamental Outlook
From a technical perspective, Tech Mahindra’s price action above all major moving averages confirms a strong uptrend. The stock’s ability to sustain levels near its 52-week high with increasing volumes and open interest is a positive sign for momentum traders and long-term investors alike.
Fundamentally, the company’s large-cap status and solid market capitalisation provide stability and liquidity, making it an attractive option for institutional investors. The Mojo Score upgrade to Buy further validates the company’s improving financial metrics and growth outlook within the competitive software and consulting industry.
Investors should monitor open interest trends closely, as any sudden unwinding or decline in OI could signal profit-taking or a shift in sentiment. However, the current data points to a constructive market positioning with a bullish bias.
Conclusion
Tech Mahindra Ltd. is currently exhibiting strong signs of bullish market positioning, as evidenced by a 13.02% surge in open interest in derivatives, robust volume, and price gains near its 52-week high. The stock’s upgrade to a Buy rating and solid fundamentals underpin this positive momentum. While broader market indices have shown weakness, Tech Mahindra’s relative strength and rising investor participation suggest it could continue to outperform in the near term. Market participants should watch for sustained open interest growth and volume to confirm the durability of this uptrend.
