Tata Power Company Sees Heavy Put Option Activity Ahead of December Expiry

Put Option Activity Concentrated Near Current Market Levels

Data from the derivatives market shows that Tata Power Company Ltd’s put options with strike prices of ₹390, ₹395, and ₹400 for the 30 December 2025 expiry date have recorded the highest volumes among active contracts. The underlying stock price stood at ₹396.95 at the time of analysis, placing these strike prices in close proximity to the current market value.

The ₹390 strike put option saw 1,392 contracts traded, generating a turnover of approximately ₹94.06 lakhs and an open interest of 2,422 contracts. Meanwhile, the ₹395 strike recorded 1,182 contracts traded with a turnover of ₹109.86 lakhs and an open interest of 460 contracts. The ₹400 strike put option led in turnover with ₹162.05 lakhs on 1,301 contracts traded and an open interest of 1,662 contracts.

This clustering of put option activity near the stock’s prevailing price suggests that investors are positioning for potential downside risk or seeking protection against volatility in the near term. The open interest figures indicate that a sizeable number of contracts remain outstanding, which could influence price movements as expiry approaches.

Stock Performance and Market Context

Despite the heavy put option interest, Tata Power Company’s equity has demonstrated resilience in recent sessions. The stock outperformed its sector by 1.52% on the day, registering a 1.46% gain compared to the sector’s 0.16% and the Sensex’s 0.11% returns. Over the last two trading days, the stock has delivered a cumulative return of 5.05%, reflecting positive momentum.

Intraday, Tata Power touched a high of ₹399.95, marking a 2.16% rise from previous levels. The stock is trading above its key moving averages, including the 5-day, 20-day, 50-day, 100-day, and 200-day averages, signalling a generally bullish technical backdrop. However, delivery volumes have shown a decline, with 24.11 lakh shares delivered on 26 November, down 6.49% against the five-day average delivery volume, indicating a slight reduction in investor participation.

Liquidity remains adequate for sizeable trades, with the stock’s average traded value supporting transaction sizes up to ₹3.82 crore based on 2% of the five-day average traded value. Tata Power’s market capitalisation stands at ₹1,26,918.89 crore, categorising it as a large-cap stock within the power sector.

Implications of Put Option Concentration

The concentration of put option trades at strikes near the current price level often reflects a cautious stance among investors. Such activity can be interpreted as a hedge against potential declines or as a speculative bet on downward price movement. The relatively high open interest at the ₹390 and ₹400 strikes indicates that these levels are key reference points for market participants.

Given the expiry date of 30 December 2025, traders may be positioning ahead of year-end events, earnings announcements, or sector-specific developments that could impact Tata Power’s share price. The power sector, influenced by regulatory changes, fuel costs, and demand fluctuations, often experiences volatility that investors seek to manage through options.

Sector and Broader Market Comparison

Within the power sector, Tata Power’s recent outperformance contrasts with the sector’s modest gains, highlighting its relative strength. However, the presence of significant put option activity suggests that some investors are factoring in risks that could temper the stock’s advance. This duality underscores the complex market assessment surrounding Tata Power’s near-term prospects.

Comparing the stock’s movement to the Sensex, which recorded a 0.11% gain, Tata Power’s 1.46% rise indicates a degree of investor preference or sector-specific momentum. Yet, the option market data reveals a nuanced picture where hedging and bearish positioning coexist with positive price action.

Outlook and Investor Considerations

Investors analysing Tata Power Company should weigh the recent positive price momentum against the evident caution reflected in the options market. The heavy put option activity near the current price level may indicate expectations of increased volatility or downside risk in the coming weeks. This could be driven by sector-specific factors such as regulatory announcements, fuel price movements, or broader macroeconomic conditions affecting power demand.

For traders, the open interest and turnover data provide valuable insights into market sentiment and potential support or resistance levels. The expiry of these put options on 30 December 2025 will be a critical juncture, potentially influencing price dynamics as positions are squared off or rolled forward.

Meanwhile, the stock’s technical positioning above key moving averages suggests underlying strength, which may counterbalance bearish pressures. The decline in delivery volumes could signal a temporary pullback in investor enthusiasm, warranting close monitoring of volume trends in the near term.

Overall, Tata Power Company’s option market activity offers a window into investor hedging strategies and risk management approaches, complementing the equity’s recent performance and sector context.

Summary

Tata Power Company Ltd’s put option market has seen concentrated activity at strike prices ₹390, ₹395, and ₹400 ahead of the December 2025 expiry, reflecting notable bearish positioning or hedging. Despite this, the stock has recorded gains over recent sessions, outperforming its sector and trading above key moving averages. The interplay between option market caution and equity strength highlights a complex market assessment as investors navigate sector-specific and broader economic factors.
