Interglobe Aviation Sees Heavy Put Option Activity Ahead of December Expiry

Put Option Activity Concentrated Near Current Market Levels

Data from recent trading sessions reveals that Interglobe Aviation’s put options expiring on 30 December 2025 have seen substantial volumes across multiple strike prices. The underlying stock, trading at ₹4,913, has witnessed the highest put contract trades at strike prices ranging from ₹4,300 to ₹4,950. Notably, the 4,300 strike price recorded 3,260 contracts traded with an open interest of 3,562, while the 4,950 strike saw 2,414 contracts traded and an open interest of 1,073.

The turnover for these put options is also significant, with the 4,950 strike generating ₹7.09 crores and the 4,750 strike producing ₹3.91 crores in turnover. This level of activity indicates that investors are positioning themselves for potential downside or are employing protective strategies against adverse price movements in the near term.

Expiry Patterns and Open Interest Insights

All the put options under scrutiny share the same expiry date of 30 December 2025, suggesting a concentrated focus on the year-end timeframe. Open interest figures further highlight the concentration of positions, with the 4,600 strike price showing an open interest of 2,505 contracts and the 4,400 strike at 2,460 contracts. These numbers suggest that traders are maintaining or building positions rather than closing them out, which could imply expectations of volatility or price pressure as the expiry date nears.

Stock Performance Context

Interglobe Aviation’s stock performance on the day aligns closely with its sector peers, with a 1-day return of -1.43% compared to the airline sector’s -0.73%. The stock touched an intraday low of ₹4,854, representing a 2.28% dip from previous levels. The weighted average price indicates that more volume traded near this low price, suggesting selling pressure or cautious buying interest at these levels.

Technical indicators show that Interglobe Aviation is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, signalling a prevailing downward trend across multiple timeframes. Additionally, delivery volumes on 9 December reached 34.99 lakh shares, marking a 13.69% rise against the five-day average delivery volume, which points to increased investor participation amid the recent price movements.

Market Capitalisation and Liquidity Considerations

Interglobe Aviation is classified as a large-cap stock with a market capitalisation of approximately ₹1,91,880 crores. This sizeable market cap underlines the company’s prominence within the airline sector and the broader market. Liquidity metrics indicate that the stock is sufficiently liquid to support sizeable trades, with a trading capacity of around ₹81.81 crores based on 2% of the five-day average traded value. This liquidity facilitates active participation from institutional and retail investors alike.

Investor Sentiment and Hedging Strategies

The pronounced put option activity at strike prices below and near the current market value suggests a cautious or bearish stance among traders. Such positioning may be driven by concerns over sector-specific challenges, including fluctuating fuel costs, regulatory changes, or broader economic uncertainties impacting air travel demand. Alternatively, some investors might be employing these put options as hedges to protect existing long positions in Interglobe Aviation shares against potential downside risks.

Given the expiry date at the end of December, these options could also reflect year-end portfolio adjustments or risk management strategies ahead of the new calendar year. The concentration of open interest at multiple strike prices indicates that market participants are actively managing exposure across a range of potential price scenarios.

Sector and Broader Market Comparison

While Interglobe Aviation’s one-day return of -1.43% is more pronounced than the airline sector’s -0.73%, it contrasts with the Sensex’s modest positive return of 0.28% on the same day. This divergence highlights sector-specific pressures that may be influencing investor behaviour towards airline stocks, including Interglobe Aviation. The airline sector’s sensitivity to external factors such as fuel price volatility, geopolitical developments, and travel demand fluctuations often results in heightened market responsiveness compared to broader indices.

Investors monitoring Interglobe Aviation’s option activity should consider these sector dynamics alongside the company’s individual performance metrics and market positioning.

Outlook and Considerations for Investors

Given the current put option volumes and open interest, market participants appear to be preparing for potential downside or increased volatility in Interglobe Aviation’s share price as the December expiry approaches. The stock’s trading below key moving averages and the recent intraday lows reinforce this cautious stance. However, the increased delivery volumes suggest active investor engagement, which could lead to price stabilisation or reversal depending on broader market developments.

Investors should weigh these factors carefully, considering both the risks implied by the options market and the company’s fundamental position within the airline sector. Monitoring upcoming sector news, macroeconomic indicators, and company-specific announcements will be crucial in assessing the evolving market sentiment towards Interglobe Aviation.

Summary

Interglobe Aviation’s put option market activity ahead of the 30 December 2025 expiry reveals a landscape of cautious positioning and hedging. The concentration of contracts at strike prices near and below the current stock price, combined with significant open interest, points to expectations of potential price pressure or volatility. This activity occurs against a backdrop of the stock trading below multiple moving averages and experiencing increased delivery volumes, underscoring a complex market environment for this large-cap airline stock.

Investors and traders should remain attentive to these signals as they navigate the closing weeks of the year, balancing the insights from options market data with broader sector and macroeconomic trends.
