Tata Power Sees Heavy Call Option Activity as Stock Nears 52-Week High

Robust Call Option Trading Highlights Bullish Sentiment

The power sector heavyweight, Tata Power, recorded a remarkable 4,627 call option contracts traded for the 30 March 2026 expiry at the ₹420 strike price. This activity generated a turnover of ₹241.53 lakhs, underscoring strong market interest in the stock’s near-term upside potential. Open interest stands at 4,966 contracts, indicating sustained investor commitment to these bullish bets.

Currently, Tata Power’s underlying stock price is ₹404.0, trading just 3.4% below its 52-week high of ₹416.8. The proximity to this peak, combined with the concentration of call options at ₹420, suggests traders anticipate a breakout above this resistance level before the expiry date.

Price and Volume Trends Support Positive Outlook

Over the past two trading sessions, Tata Power has delivered a cumulative return of 3.21%, outperforming the sector’s 0.34% and the Sensex’s 0.56% gains on the most recent day. The stock’s trading range has been relatively narrow at ₹3.2, reflecting consolidation ahead of a potential directional move.

Notably, Tata Power is trading above all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling a sustained uptrend. Investor participation has also increased, with delivery volumes on 17 March reaching 50.94 lakh shares, a 7.62% rise compared to the five-day average. This heightened liquidity supports the feasibility of executing sizeable trades, with an average daily traded value sufficient to accommodate Rs 11.09 crore in trade size.

Mojo Score and Rating Context

Despite the bullish option activity, Tata Power’s MarketsMOJO score remains subdued at 37.0, with a current Mojo Grade of Sell. This represents an improvement from a previous Strong Sell rating assigned on 24 February 2026, reflecting some stabilisation in fundamentals or market perception. The company is classified as a large-cap stock with a market capitalisation of ₹1,29,203.55 crore, operating within the power industry and sector.

Expiry Patterns and Strike Price Concentration

The concentration of call option activity at the ₹420 strike price for the 30 March expiry is particularly noteworthy. This strike is approximately 4% above the current market price, indicating that traders are positioning for a moderate upside within the next two weeks. The open interest level of 4,966 contracts at this strike is among the highest for Tata Power, suggesting it is a key focal point for options traders.

Such positioning often reflects expectations of positive catalysts or technical breakouts. Given Tata Power’s recent price momentum and strong moving average support, the market appears to be pricing in a potential rally that could push the stock beyond the ₹420 level before expiry.

Comparative Sector and Market Performance

While Tata Power’s one-day return of 0.87% slightly outpaces the Sensex’s 0.56% and the power sector’s 0.34%, the stock’s recent gains over two days have been more pronounced. This relative outperformance, coupled with rising delivery volumes, suggests growing investor confidence in the company’s near-term prospects despite the cautious Mojo Grade.

Investors should note that the power sector is currently navigating a complex environment with regulatory changes and fluctuating commodity prices. Tata Power’s ability to maintain upward momentum amid these challenges is a positive signal, but the sell-grade rating advises prudence.

Investor Takeaway and Outlook

The surge in call option activity for Tata Power at the ₹420 strike price ahead of the 30 March expiry reflects a cautiously optimistic market stance. The stock’s proximity to its 52-week high, combined with strong technical indicators and rising delivery volumes, supports the case for a potential near-term rally.

However, the current Mojo Grade of Sell and a modest Mojo Score of 37.0 indicate underlying concerns that investors should weigh carefully. The recent upgrade from Strong Sell to Sell suggests some improvement in fundamentals or sentiment, but the company has yet to demonstrate a decisive turnaround.

For investors considering exposure to Tata Power, the active call option positioning offers a window into market expectations but also highlights the need for vigilance given sector headwinds and valuation considerations. Monitoring price action around the ₹420 strike and expiry date will be critical to gauge whether bullish momentum sustains or dissipates.

Overall, Tata Power remains a large-cap power sector stock with mixed signals: technical strength and bullish option interest on one hand, and a cautious fundamental rating on the other. This duality underscores the importance of a balanced approach when analysing the stock’s prospects in the current market environment.
