Tata Power Sees Heavy Call Option Activity Ahead of March Expiry

Robust Call Option Volumes Signal Investor Interest

The most active call options for Tata Power are concentrated on the 30 March 2026 expiry, with three key strike prices drawing substantial volumes. The ₹400 strike call leads with 30,146 contracts traded, generating a turnover of approximately ₹4,716.5 lakhs and an open interest of 2,336 contracts. Close behind, the ₹420 strike call saw 22,817 contracts traded, with turnover of ₹1,535.1 lakhs and open interest rising to 2,495 contracts. The ₹410 strike call also attracted notable activity, with 16,025 contracts traded and turnover of ₹1,707.9 lakhs, alongside an open interest of 1,529 contracts.

These figures indicate a strong bullish sentiment among options traders, who appear to be positioning for a potential upward move in Tata Power’s share price over the coming weeks. The underlying stock closed at ₹401.95, just 4.25% shy of its 52-week high of ₹416.8, suggesting that market participants are anticipating a near-term rally or at least a consolidation near recent highs.

Stock Performance and Technical Context

Despite the bullish options activity, Tata Power’s stock price underperformed its sector on 13 March 2026, declining by 0.94% compared to a sector gain of 0.40%. This underperformance followed a three-day streak of gains, signalling a possible short-term correction or profit-taking phase. However, the stock remains technically strong, trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, which typically indicates a sustained uptrend.

Investor participation has notably increased, with delivery volumes on 12 March reaching 98.2 lakh shares — a 248.61% rise over the five-day average. This surge in delivery volume underscores heightened investor interest and liquidity, supporting the active options market.

Mojo Score and Market Capitalisation Insights

Tata Power holds a large-cap status with a market capitalisation of ₹1,28,549 crores. However, its current Mojo Score stands at 34.0, reflecting a 'Sell' grade as of 24 February 2026, a downgrade from the previous 'Strong Sell' rating. This shift suggests some improvement in fundamentals or market perception, but the stock still faces challenges that temper enthusiasm among fundamental investors.

The downgrade may be attributed to sector headwinds or company-specific factors, but the active call option interest indicates that traders are betting on a near-term price recovery or volatility-driven opportunities. The divergence between fundamental ratings and options market activity is not uncommon, as options traders often capitalise on short-term price movements irrespective of long-term outlooks.

Expiry Patterns and Strike Price Concentration

The concentration of call option activity at the ₹400, ₹410, and ₹420 strike prices for the 30 March expiry reveals a strategic positioning by market participants. The ₹400 strike, being closest to the current underlying price, has the highest turnover and contract volume, signalling a strong expectation that the stock will at least hold or surpass this level by expiry.

The higher strike prices of ₹410 and ₹420 also show considerable open interest, suggesting that some traders are targeting a more optimistic price scenario. This layered strike price interest provides a nuanced view of market sentiment, with a base expectation of stability or modest gains and a subset of investors anticipating a stronger rally.

Liquidity and Trading Viability

Tata Power’s liquidity profile supports active trading, with the stock’s average traded value allowing for trade sizes up to ₹8.8 crores based on 2% of the five-day average. This liquidity is crucial for options traders who require efficient entry and exit points without significant price impact. The high delivery volumes and active options market confirm that Tata Power remains a preferred stock for both equity and derivatives traders.

Balancing Bullish Options Activity with Fundamental Caution

While the options market activity points to bullish positioning, investors should weigh this against the fundamental outlook and recent rating downgrade. The power sector faces regulatory and commodity price risks that could impact Tata Power’s earnings trajectory. Moreover, the stock’s recent underperformance relative to its sector and the broader Sensex decline of 0.84% on 13 March 2026 highlight prevailing market uncertainties.

Nonetheless, the stock’s proximity to its 52-week high and strong technical indicators may provide a foundation for a rebound, especially if sector conditions improve or company-specific catalysts emerge. The active call option interest could also reflect hedging strategies or speculative plays on volatility ahead of the expiry date.

Outlook and Investor Considerations

For investors and traders, Tata Power presents a complex picture. The large-cap status and liquidity make it an attractive candidate for portfolio inclusion or tactical trades. However, the current Mojo Grade of 'Sell' advises caution, suggesting that investors should monitor developments closely and consider risk management strategies.

Options traders appear to be positioning for a potential upside, but the mixed signals from fundamental analysis and recent price action warrant a balanced approach. Those bullish on the stock may focus on the ₹400 to ₹420 strike range for potential gains, while more conservative investors might await clearer signs of trend confirmation or sector recovery.

Summary

Tata Power Company Ltd’s call options market activity ahead of the 30 March 2026 expiry reveals strong investor interest in strike prices near the current trading level, signalling bullish sentiment despite a recent downgrade to a 'Sell' rating. The stock’s technical strength and rising delivery volumes support this optimism, although fundamental challenges and sector dynamics counsel prudence. As expiry approaches, market participants will closely watch price movements and volume trends to gauge the sustainability of this positioning.
