Robust Call Option Activity Highlights Investor Optimism
On 12 Mar 2026, Tata Power’s call options for the 30-Mar-2026 expiry dominated the derivatives market in terms of volume and turnover. The strike prices of ₹390 and ₹400 emerged as the most actively traded, with 3,679 and 4,350 contracts exchanged respectively. The turnover for the ₹390 strike call options reached ₹581.99 lakhs, while the ₹400 strike calls accounted for ₹411.25 lakhs in turnover. Open interest figures further underscore sustained investor interest, standing at 1,658 contracts for the ₹390 strike and 2,628 contracts for the ₹400 strike.
The underlying stock price of Tata Power closed at ₹391.0, positioning the ₹390 strike calls just at-the-money and the ₹400 strike calls slightly out-of-the-money. This concentration of activity near the current market price suggests traders are positioning for a potential upward move in the coming weeks.
Price Performance and Technical Indicators Support Bullish Outlook
Tata Power has outperformed its sector peers, delivering a 1.39% gain on the day compared to the power sector’s 0.81% rise and the Sensex’s 1.10% decline. The stock has recorded gains for three consecutive sessions, accumulating a 4.92% return over this period. Notably, Tata Power is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, signalling a strong technical uptrend.
Investor participation has also intensified, with delivery volumes on 11 Mar reaching 36.57 lakh shares, a 36.17% increase over the five-day average. This surge in delivery volume indicates genuine buying interest rather than speculative trading, reinforcing the bullish narrative.
Market Capitalisation and Quality Metrics
Despite the positive price action, Tata Power’s MarketsMOJO score remains subdued at 34.0, with a Mojo Grade of Sell as of 24 Feb 2026, downgraded from a previous Strong Sell rating. The company holds a Market Cap Grade of 1, reflecting its large-cap status with a market capitalisation of ₹1,24,969.73 crores. While the fundamental score suggests caution, the technical momentum and options market activity point to a more optimistic near-term outlook.

Expiry Patterns and Strike Price Concentration
The expiry date of 30 Mar 2026 is attracting the bulk of call option activity, indicating that traders are focusing on short-term catalysts or events that could drive the stock price higher within the next three weeks. The clustering of contracts at ₹390 and ₹400 strikes suggests a consensus expectation that Tata Power will trade above these levels by expiry, reflecting a moderately bullish stance.
Open interest data reveals that the ₹400 strike has the highest outstanding contracts, implying that many investors are either holding onto bullish positions or are prepared to exercise calls if the stock breaches this level. The sizeable turnover at these strikes also points to active position adjustments and new entries, signalling dynamic market participation.
Liquidity and Trading Viability
Tata Power’s liquidity profile supports sizeable trades, with the stock’s average traded value allowing for a trade size of approximately ₹5.3 crores based on 2% of the five-day average. This liquidity ensures that institutional and retail investors can execute large orders without significant market impact, further encouraging options activity.
Balancing Bullish Sentiment with Fundamental Caution
While the technical and options market indicators suggest a bullish near-term outlook, investors should weigh these against the company’s fundamental assessment. The downgrade from Strong Sell to Sell in the Mojo Grade reflects underlying concerns, possibly related to earnings, sector challenges, or valuation metrics. This divergence between technical optimism and fundamental caution warrants a measured approach.

Implications for Investors and Traders
For investors, the surge in call option activity around near-the-money strikes and the stock’s strong technical positioning may signal an opportunity to capitalise on upward momentum. Traders could consider strategies such as buying calls or call spreads to benefit from anticipated price appreciation ahead of the 30 Mar expiry.
However, given the company’s current Mojo Grade of Sell and the inherent volatility in the power sector, risk management remains paramount. Investors should monitor open interest trends and price action closely, particularly as expiry approaches, to adjust positions accordingly.
Sector Context and Comparative Performance
Tata Power’s outperformance relative to the power sector and broader market indices highlights its relative strength in a challenging environment. The sector’s 0.81% gain pales in comparison to Tata Power’s 1.39% rise on the day, while the Sensex declined by 1.10%. This divergence underscores the stock’s appeal as a potential outperformer within its industry group.
Moreover, the company’s large-cap status and substantial market capitalisation provide a degree of stability and investor confidence, which may be attracting options traders seeking exposure to a blue-chip power stock with upside potential.
Conclusion: A Cautiously Bullish Outlook Supported by Options Market
The heightened call option activity in Tata Power Company Ltd, particularly at the ₹390 and ₹400 strike prices expiring on 30 Mar 2026, reflects a growing bullish sentiment among market participants. Supported by strong technical indicators and rising investor participation, the stock appears poised for further gains in the near term.
Nonetheless, the fundamental caution signalled by the Mojo Grade Sell rating advises prudence. Investors and traders should balance the technical optimism with underlying company metrics and sector dynamics before committing capital.
Overall, Tata Power remains a stock to watch closely as expiry approaches, with options market data providing valuable insights into investor expectations and potential price trajectories.
