Put Option Activity Concentrated Near Current Market Levels
Data from recent trading sessions reveals that Interglobe Aviation's put options have been among the most actively traded in the market. The underlying stock, trading at ₹4,885, has seen substantial put option volumes clustered around strike prices ranging from ₹4,500 to ₹4,900. Notably, the strike price of ₹4,800 recorded the highest number of contracts traded, with 3,496 contracts exchanging hands, generating a turnover of approximately ₹4.78 crores. This strike also holds an open interest of 5,241 contracts, indicating sustained investor interest at this level.
Other significant strike prices include ₹4,700 with 2,122 contracts traded and an open interest of 3,640, and ₹4,900 with 1,844 contracts traded and an open interest of 3,130. The ₹4,600 and ₹4,500 strikes also show considerable activity, with 1,840 and 2,339 contracts traded respectively, and open interest figures of 3,002 and 6,149 contracts. The ₹4,500 strike notably carries the highest open interest among these, suggesting a strong base of put holders at this level.
Expiry Patterns and Investor Positioning
All these put options are set to expire on 30 December 2025, marking the end of the current quarterly cycle. The concentration of open interest and turnover in these strikes suggests that investors are positioning themselves for potential downside protection or speculative plays in the coming weeks. The clustering of activity just below and slightly above the current market price indicates a cautious stance, with market participants possibly hedging against near-term volatility or anticipating a price correction.
Stock Performance and Market Context
Interglobe Aviation's stock has shown a modest gain of 1.39% on the day, slightly outperforming the broader airline sector's 1.28% rise and the Sensex's 0.51% increase. The stock has recorded gains over the last two consecutive days, delivering a cumulative return of 1.72% during this period. Despite this short-term positive momentum, the share price remains below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating that the broader trend may still be under pressure.
Investor participation appears to be waning, with delivery volumes on 11 December falling to 29.52 lakh shares, a decline of 28.29% compared to the five-day average delivery volume. This reduction in active investor engagement could be contributing to the cautious positioning observed in the options market.
Liquidity remains adequate for sizeable trades, with the stock's average traded value supporting transactions up to approximately ₹97.31 crores based on 2% of the five-day average traded value. Interglobe Aviation's market capitalisation stands at ₹1,86,312 crores, categorising it firmly as a large-cap stock within the airline sector.

Bearish Positioning and Hedging Implications
The prominence of put options at strike prices below the current market value suggests that investors may be seeking downside protection or speculating on a potential decline in Interglobe Aviation's share price. The sizeable open interest at the ₹4,500 and ₹4,800 strikes, in particular, points to a significant number of contracts that could be exercised or offset if the stock moves lower.
Put options serve as a common hedging tool for shareholders looking to mitigate losses in volatile sectors such as airlines, which are often sensitive to fuel prices, regulatory changes, and economic cycles. The airline industry has faced fluctuating demand patterns and cost pressures, factors that may be influencing the cautious stance reflected in the options market.
Moreover, the expiry date of 30 December 2025 is approaching, which typically leads to increased activity as traders adjust or close positions. The clustering of put option interest around these strike prices may also reflect strategic positioning ahead of year-end financial results or macroeconomic developments.
Comparative Sector and Market Performance
While Interglobe Aviation's stock has outperformed the Sensex and matched the sector's daily returns, the broader technical indicators suggest a more complex picture. Trading below all major moving averages indicates that the stock has yet to establish a sustained upward trend. This technical backdrop, combined with falling delivery volumes, may be contributing to the increased demand for downside protection via put options.
Investors and traders monitoring the airline sector should consider these factors alongside broader market conditions, including fuel price trends, passenger traffic data, and regulatory announcements, which can all impact airline stock performance.

Outlook and Investor Considerations
As the December expiry approaches, market participants will be closely watching Interglobe Aviation's price movements and option open interest changes. The current put option activity suggests a degree of caution or hedging, which may signal expectations of volatility or price corrections in the near term.
Investors should weigh these signals alongside fundamental factors such as the airline's operational performance, fuel cost trends, and broader economic indicators. The airline sector's sensitivity to external shocks means that option market activity can provide valuable insights into market sentiment and risk management strategies.
Given the stock's large market capitalisation and liquidity, Interglobe Aviation remains a key focus for institutional and retail investors alike. Monitoring option expiry dynamics and strike price concentrations can aid in understanding potential support and resistance levels, as well as investor risk appetite.
Summary
Interglobe Aviation's put option market activity ahead of the 30 December 2025 expiry reveals a pronounced interest in downside protection at strike prices close to the current share price. The volume and open interest data indicate that investors are positioning for potential volatility or price adjustments in the airline stock. While the stock has shown recent gains, technical indicators and declining delivery volumes suggest a cautious market environment. These factors combined underscore the importance of closely monitoring option market trends as part of a comprehensive investment analysis in the airline sector.
