Rs 4,100 Puts Draw 3,226 Contracts on Interglobe Aviation Ltd Ahead of 30-Mar Expiry

Put Options Event and Cash Market Context

On the expiry day of 30 March 2026, Interglobe Aviation Ltd saw significant put option turnover, with the Rs 4,100 strike registering 3,226 contracts traded, generating a turnover of approximately ₹1.67 crores. Other strikes also showed activity: Rs 4,050 with 7,381 contracts and Rs 4,000 with 6,820 contracts traded, indicating a broad interest in put options near the current price. The underlying stock closed at Rs 4,079.7, down 1.38% on the day, and trading below all major moving averages (5-day, 20-day, 50-day, 100-day, and 200-day), reflecting a bearish technical backdrop.

The stock’s intraday volatility was elevated at 13.02%, and delivery volumes rose by 33.28% compared to the five-day average, suggesting active participation in the cash market. Despite the decline, the stock outperformed its sector by 1.35%, adding nuance to the price action. Interglobe Aviation Ltd remains a large-cap airline stock with a market capitalisation of ₹1,58,500 crores, making its options activity particularly relevant for institutional players.

Strike Price Analysis: Moneyness and Distance from Underlying

The Rs 4,100 put strike sits just 0.5% out-of-the-money (OTM) relative to the closing price of Rs 4,079.7, while the Rs 4,050 and Rs 4,000 strikes are 0.7% in-the-money (ITM) and 2% ITM respectively. The concentration of contracts at these strikes suggests a focus on near-the-money protection or speculative positioning. The Rs 4,100 strike’s proximity to the current price means it is sensitive to small price moves, making it a natural choice for hedging or directional bets.

Lower strikes such as Rs 3,950, which is 3.2% below the current price, saw 4,277 contracts traded but with a much smaller open interest of 1,303, indicating less sustained interest at deeper OTM levels. The open interest at Rs 4,100 stands at 3,801 contracts, suggesting that a significant portion of the traded contracts represent fresh positions rather than rollovers.

Interpreting the Put Activity: Hedging, Bearish Positioning, or Put Writing?

Put option activity can be ambiguous, especially when the stock is trading near or below key moving averages. The near-the-money Rs 4,100 and Rs 4,050 strikes’ heavy volumes and open interest imply a mix of strategies. Given the stock’s recent decline and technical weakness, some put buying likely reflects bearish positioning, anticipating further downside or protection against a continued fall.

However, the presence of substantial open interest and turnover at slightly OTM strikes like Rs 4,100 also points to hedging activity by long holders seeking to protect gains or limit losses amid volatility. The fact that the stock remains above Rs 4,000, a psychological support level, and the Rs 4,000 strike itself has high open interest, suggests that some investors may be using puts as insurance rather than outright bearish bets.

Put writing, or selling puts to collect premium, is less evident here given the elevated premiums and the stock’s technical weakness. The turnover and open interest ratios do not strongly support a dominant put writing narrative, which would typically involve high open interest with relatively low fresh contract volumes and a strike price comfortably OTM. Interglobe Aviation Ltd’s put activity thus appears to be a blend of protective hedging and cautious bearish positioning rather than outright bullish put selling.

Open Interest and Contracts Analysis

The ratio of contracts traded to open interest at the Rs 4,100 strike is approximately 0.85, indicating that a large portion of the activity represents fresh positions or adjustments rather than mere rollovers. The Rs 4,050 strike shows a similar pattern with 7,381 contracts traded against 3,883 open interest, a ratio of nearly 1.9, signalling active repositioning. This fresh activity suggests that traders are actively recalibrating their risk exposure ahead of expiry, possibly in response to recent price volatility and technical signals.

Lower strikes such as Rs 3,950 have a lower ratio of traded contracts to open interest, implying more established positions. The overall open interest distribution across strikes near the current price supports a scenario where market participants are balancing between downside protection and speculative bearish bets.

Cash Market Context: Technicals and Delivery Volumes

Interglobe Aviation Ltd is trading below all major moving averages, including the 5-day, 20-day, 50-day, 100-day, and 200-day, signalling a bearish technical environment. The stock’s recent intraday volatility of 13.02% and a 1.38% decline on the day reinforce this view. However, the stock outperformed its sector by 1.35%, suggesting relative resilience amid broader weakness.

Delivery volumes rose by 33.28% compared to the five-day average, indicating increased investor participation in the cash market. This heightened activity may be driving the demand for protective puts as investors seek to guard against further downside in a volatile environment. Interglobe Aviation Ltd’s price action and delivery data together suggest that the put buying is more likely a defensive manoeuvre than a pure directional bearish bet — should investors consider hedging their positions as volatility persists?

Key Data at a Glance

Conclusion: Protective Hedging Dominates Put Activity

The put option activity in Interglobe Aviation Ltd ahead of the 30 March expiry reveals a nuanced picture. The concentration of contracts near the current price, combined with the stock’s technical weakness and elevated volatility, suggests that the put buying is primarily protective hedging by long holders rather than outright bearish speculation or put writing.

While some bearish positioning is evident, the data does not support a dominant negative conviction given the stock’s relative outperformance and rising delivery volumes. The fresh open interest and turnover ratios indicate active risk management rather than speculative panic. With puts active and calls also showing interest, what is the best approach to navigating Interglobe Aviation Ltd’s options landscape?
