Intense Put Option Trading Highlights Bearish Sentiment
On 30 December 2025 expiry, Mazagon Dock Shipbuilders Ltd saw two strike prices dominate put option volumes: ₹2,450 and ₹2,500. The ₹2,500 strike price led with 5,190 contracts traded, generating a turnover of ₹99.18 lakhs and an open interest of 1,100 contracts. Meanwhile, the ₹2,450 strike price recorded 3,026 contracts traded, turnover of ₹17.74 lakhs, and open interest of 1,223 contracts. These figures underscore a pronounced bearish bias among options traders, who appear to be positioning for a potential decline or hedging existing long exposures.
The underlying stock price stood at ₹2,500.3 on the day, placing the ₹2,500 strike price essentially at-the-money, while the ₹2,450 strike price was slightly out-of-the-money. The concentration of put activity at these levels suggests investors are bracing for a possible dip below current market prices in the near term.
Price and Technical Trends Confirm Downside Pressure
Mazagon Dock’s recent price action aligns with the options market sentiment. The stock has declined for two consecutive sessions, losing approximately 1.3% over this period. Its one-day return was -1.51%, slightly underperforming the Aerospace & Defence sector’s 1.18% fall and the broader Sensex’s marginal 0.02% dip. Notably, the stock is trading below all major moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling sustained downward momentum.
Investor participation has risen sharply, with delivery volumes on 29 December reaching 5.35 lakh shares, a 51.71% increase over the five-day average. This heightened activity, combined with the stock’s liquidity supporting trade sizes up to ₹10 crore, indicates active repositioning by market participants amid the prevailing bearish outlook.

Fundamental and Market Context
Mazagon Dock Shipbuilders Ltd is a large-cap company with a market capitalisation of ₹1,02,378 crore, operating in the Aerospace & Defence industry. Despite its scale, the company’s Mojo Score has deteriorated to 44.0, resulting in a downgrade from Hold to Sell as of 2 December 2025. This downgrade reflects concerns over the company’s near-term prospects and valuation pressures amid sectoral headwinds.
The company’s Market Cap Grade remains at 1, indicating its large-cap status, but the recent negative price momentum and bearish options positioning suggest investors are increasingly cautious. The Aerospace & Defence sector itself has been under pressure, with the sector index falling 1.18% on the day, marginally less than Mazagon Dock’s decline.
Options Expiry Patterns and Investor Strategies
The expiry date of 30 December 2025 is a critical juncture for options traders. The heavy put option volumes at ₹2,450 and ₹2,500 strike prices indicate that investors are either hedging long positions or speculating on a downside move. Open interest figures of 1,100 and 1,223 contracts respectively suggest that these positions are not merely intraday trades but part of a broader strategic stance.
Such concentrated put activity often precedes increased volatility around expiry, as traders adjust or roll over positions. The fact that the underlying stock is trading below all key moving averages further supports the bearish narrative, with technical traders likely to monitor these strike prices as potential support or breakout levels.
Implications for Investors and Traders
For investors, the combination of a Sell rating, deteriorating Mojo Score, and heavy put option interest signals caution. Those holding Mazagon Dock shares may consider protective strategies such as buying puts or tightening stop-loss levels to mitigate downside risk. Traders might also look for opportunities to capitalise on volatility spikes around expiry, particularly given the stock’s liquidity and active participation.
Conversely, contrarian investors could monitor for signs of capitulation or oversold conditions, especially if the stock approaches the ₹2,450 strike price with sustained put selling or unwinding. However, given the current technical and fundamental backdrop, a cautious stance remains prudent.

Conclusion: Bearish Positioning Dominates Ahead of Expiry
The surge in put option activity for Mazagon Dock Shipbuilders Ltd ahead of the 30 December 2025 expiry reflects a clear bearish sentiment among investors and traders. With the stock trading below all major moving averages and a recent downgrade to Sell, the market is signalling caution. The concentrated open interest at ₹2,450 and ₹2,500 strike prices highlights key levels to watch for potential downside or support.
Investors should carefully assess their exposure and consider hedging strategies, while traders may find opportunities in the heightened volatility expected around expiry. As always, monitoring sector trends and broader market conditions will be essential to navigate the evolving landscape for this Aerospace & Defence heavyweight.
