Interglobe Aviation Sees Heavy Put Option Activity Ahead of March Expiry

Put Option Activity Highlights

Data from the derivatives market reveals that Interglobe Aviation's put options with strike prices of ₹4,300 and ₹4,400 have been the most actively traded. Specifically, 2,087 contracts were traded at the ₹4,300 strike, generating a turnover of ₹211.06 lakhs, while the ₹4,400 strike saw 2,126 contracts traded with a turnover of ₹341.61 lakhs. Open interest stands at 2,403 and 1,846 contracts respectively for these strikes, indicating substantial investor interest in downside protection or speculative bearish bets.

The underlying stock price of IndiGo closed at ₹4,348.4 on 18 March 2026, placing the ₹4,300 and ₹4,400 strike puts near-the-money. This proximity to the current market price enhances the attractiveness of these options for hedging or directional plays, especially with expiry just around the corner on 30 March 2026.

Stock Performance and Market Context

Interglobe Aviation has been gaining momentum recently, with a 5.29% return over the last three trading sessions. On 18 March, the stock touched an intraday high of ₹4,417.5, marking a 3.02% increase for the day. However, the stock remains below its 20-day, 50-day, 100-day, and 200-day moving averages, despite trading above the 5-day average, signalling mixed technical signals.

Investor participation appears to be waning, with delivery volumes on 17 March falling by over 50% compared to the five-day average, suggesting reduced conviction among buyers. Liquidity remains adequate, with the stock supporting trade sizes of up to ₹16 crore based on 2% of the five-day average traded value.

Mojo Score and Analyst Ratings

Interglobe Aviation currently holds a Mojo Score of 33.0, categorised as a 'Sell' grade, downgraded from 'Hold' on 3 December 2025. This downgrade reflects deteriorating fundamentals or market outlook as assessed by MarketsMOJO's proprietary scoring system. The company is classified as a large-cap stock with a market capitalisation of ₹1,65,770 crore, underscoring its significant presence in the airline sector.

Bearish Positioning and Hedging Implications

The concentration of put option trades at the ₹4,300 and ₹4,400 strikes suggests that market participants are positioning for a potential downside or are actively hedging existing long exposures. The open interest figures reinforce this view, as elevated open interest in puts often signals increased demand for downside protection or speculative bearish bets.

Given the expiry date of 30 March 2026, these options are likely being used to manage risk ahead of potential volatility events or earnings announcements. The airline sector, sensitive to fuel price fluctuations, regulatory changes, and travel demand, remains vulnerable to sudden shifts, which may explain the cautious stance.

Sector and Benchmark Comparison

Interglobe Aviation's one-day return of 1.65% on 18 March 2026 slightly lagged the airline sector's 1.91% gain but outperformed the Sensex's 0.56% increase. This relative performance indicates that while the stock is participating in sectoral strength, it is not leading the rally. The mixed technical indicators and falling delivery volumes further highlight investor ambivalence.

Investors should weigh these factors carefully, considering the stock's large-cap status and the recent downgrade in its Mojo Grade. The combination of technical resistance levels, bearish option positioning, and subdued investor participation suggests a cautious approach is warranted in the near term.

Investor Takeaways and Outlook

For investors and traders, the heavy put option activity in Interglobe Aviation signals a need for vigilance. While the stock has shown short-term gains, the underlying bearish sentiment reflected in the derivatives market cannot be ignored. Those holding long positions may consider protective strategies such as buying puts or tightening stop-loss levels to mitigate downside risk.

Conversely, speculative traders might view the elevated put volumes as an opportunity to capitalise on potential volatility or a pullback, especially given the stock's proximity to key moving averages and the looming expiry date.

Overall, the combination of a downgraded Mojo Grade, mixed technical signals, and significant put option interest suggests that Interglobe Aviation is at a critical juncture. Market participants should closely monitor price action and option market developments in the coming days to better gauge the stock's trajectory.

Expiry Patterns and Market Sentiment

The expiry on 30 March 2026 is shaping up to be a focal point for Interglobe Aviation's options market. The clustering of put contracts near the current price level indicates that traders are bracing for potential downside or increased volatility around this date. Such expiry patterns often precede sharp price movements as positions are squared off or rolled forward.

Given the airline sector's sensitivity to macroeconomic factors and travel demand trends, the market's cautious stance is understandable. Investors should remain alert to any news or data releases that could influence sentiment ahead of expiry.

Conclusion

Interglobe Aviation Ltd's recent surge in put option activity at near-the-money strikes ahead of the 30 March 2026 expiry highlights a growing bearish undertone despite short-term price gains. The stock's downgrade to a 'Sell' Mojo Grade and mixed technical indicators reinforce the need for prudence. Investors should consider hedging strategies or alternative opportunities within the sector as the expiry approaches, while monitoring market developments closely.
