Tata Power Sees Surge in Call Option Activity Amid Bullish Momentum

Robust Price Performance and Market Context

Tata Power, a key player in the power sector with a market capitalisation of ₹1,21,822 crores, has been on a positive trajectory over the past few sessions. The stock has gained 4.89% over the last two trading days, outperforming its sector by 1.27% and the Sensex, which declined by 0.32% on the same day. On 11 March 2026, Tata Power touched an intraday high of ₹391.95, marking a 2.79% increase from the previous close.

Technical indicators further reinforce this bullish momentum. The stock is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, signalling sustained upward momentum. Additionally, delivery volumes surged to 40.02 lakh shares on 10 March, a 64.89% increase compared to the five-day average, indicating rising investor participation and confidence.

Heavy Call Option Activity at ₹400 Strike Price

The most active call options for Tata Power are concentrated at the ₹400 strike price, with expiry set for 30 March 2026. On this expiry date, 5,974 contracts were traded, generating a turnover of approximately ₹489.42 lakhs. Open interest stands at 2,691 contracts, reflecting significant outstanding positions and sustained interest in this strike price.

Given the underlying stock price of ₹392.20, the ₹400 strike calls are positioned just out-of-the-money, suggesting that traders are anticipating a rally beyond this level within the next three weeks. The substantial volume and open interest at this strike price indicate a strong bullish bias, with market participants likely expecting Tata Power to breach the ₹400 mark before expiry.

Mojo Score and Analyst Ratings

Despite the recent bullish price action and option market activity, Tata Power’s overall Mojo Score remains subdued at 34.0, categorised as a Sell rating. This represents an improvement from its previous Strong Sell grade, which was downgraded on 24 February 2026. The market cap grade is at the lowest level of 1, reflecting concerns over valuation or other fundamental factors.

This divergence between technical optimism and fundamental caution suggests that while traders are positioning for short-term gains, longer-term investors may remain wary. The stock’s recent outperformance could be driven by sector rotation or speculative interest rather than a fundamental turnaround.

Expiry Patterns and Investor Positioning

The expiry date of 30 March 2026 is critical for Tata Power’s near-term outlook. The concentration of call option activity at the ₹400 strike price indicates that investors are betting on a price appreciation of at least 2% from the current levels within the next three weeks. This is a relatively modest target given the stock’s recent momentum and technical strength.

Open interest data suggests that many traders are holding onto these call positions, possibly anticipating further upside or using these options as part of hedging strategies. The liquidity of the stock, with a trading capacity of approximately ₹4.51 crores based on 2% of the five-day average traded value, supports active trading and efficient price discovery.

Sectoral and Market Implications

The power sector has been under pressure in recent months due to regulatory challenges and fluctuating commodity prices. Tata Power’s relative outperformance and bullish option positioning may signal a shift in investor sentiment towards the sector. However, the stock’s Mojo Grade of Sell indicates that caution is warranted, and investors should weigh the risks carefully.

Comparatively, Tata Power’s 1-day return of 2.90% outpaces the sector’s 1.27% gain, highlighting its leadership within the power space. This could attract further institutional interest if the stock sustains its momentum and breaks through key resistance levels.

Investor Takeaway

For investors tracking Tata Power, the surge in call option activity at the ₹400 strike price expiring in late March is a clear indicator of bullish sentiment in the near term. The stock’s technical strength, rising delivery volumes, and outperformance relative to its sector and the Sensex provide a supportive backdrop for potential gains.

However, the modest Mojo Score and Sell rating caution against overexuberance. Investors should consider the broader fundamental context, including regulatory risks and sector dynamics, before committing significant capital. The option market activity may be driven by short-term speculative positioning rather than a definitive fundamental turnaround.

Monitoring the stock’s ability to sustain above key moving averages and the ₹400 level will be crucial in the coming weeks. Should Tata Power break through this resistance convincingly, it could attract further buying interest and validate the bullish option positioning.

Conclusion

Tata Power Company Ltd’s recent price gains and heavy call option trading at the ₹400 strike price reflect a growing bullish consensus among traders for the near-term. While technical indicators and market participation are encouraging, the company’s fundamental rating remains cautious. Investors should balance these factors carefully and watch expiry dynamics closely as the 30 March 2026 date approaches.
