Rs 3,900 and Rs 4,000 Puts Draw Heavy Interest on Interglobe Aviation Ltd Ahead of 30 Mar Expiry

Put Options Event and Cash Market Context

On 24 March 2026, Interglobe Aviation Ltd saw 2,450 put contracts traded at the Rs 3,900 strike and 3,296 contracts at the Rs 4,000 strike, generating a combined turnover of approximately ₹277.68 lakhs. The open interest at these strikes stands at 1,421 and 3,136 contracts respectively, indicating a substantial build-up of positions ahead of the expiry in six days. The stock closed at Rs 4,058, having gained 2.75% on the day and outperforming its sector by 0.73%. This rally follows a three-day decline, signalling a potential short-term recovery phase. Is this put activity a sign of caution or confidence in the ongoing rebound?

Strike Price Analysis: Moneyness and Distance from Underlying

The Rs 3,900 put strike lies approximately 3.9% below the current market price, while the Rs 4,000 strike is about 1.4% out-of-the-money (OTM). Both strikes are close to the underlying price, with the Rs 4,000 put nearly at-the-money (ATM). The proximity of these strikes to the current price is critical in interpreting the intent behind the put activity. OTM puts at Rs 3,900 suggest a protective hedge against a moderate pullback, whereas the near-ATM Rs 4,000 puts could indicate either fresh bearish positioning or hedging of existing long exposure. The Rs 3,900 strike is also just 4.35% above the 52-week low of Rs 3,895.2, highlighting its relevance as a potential support level.

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

Put options inherently carry ambiguous signals. The heavy volume at the Rs 4,000 strike, combined with a sizeable open interest, could reflect fresh bearish bets anticipating a near-term correction. However, the stock’s recent 2.75% gain and outperformance of the airline sector complicate this view. The rally after three days of decline suggests some short-term optimism, which aligns more closely with hedging activity. Investors holding long positions may be buying OTM puts to protect gains or limit downside risk, especially given the stock remains below all major moving averages (5-day through 200-day), indicating the broader trend is still negative. Alternatively, put writing—selling puts to collect premium—would be a bullish stance, but the high turnover and open interest at these strikes suggest more buying than selling activity.

Open Interest and Contracts Analysis

The ratio of contracts traded to open interest is approximately 1.7:1 at the Rs 3,900 strike and 1.05:1 at Rs 4,000, signalling significant fresh positioning, particularly at the lower strike. This fresh activity points to new hedging or directional bets rather than mere adjustments of existing positions. The Rs 4,000 strike’s higher open interest indicates it is a focal point for traders, possibly as a technical support level or a hedge threshold. The combined open interest of 4,557 contracts at these strikes represents a meaningful portion of the total put interest in Interglobe Aviation Ltd, underscoring the importance of these levels in the options market.

Cash Market Technical Context

Despite the recent uptick, Interglobe Aviation Ltd remains below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, reflecting a prevailing downtrend. The Rs 3,900 and Rs 4,000 strikes roughly correspond to a support zone near the 52-week low, which may explain the concentration of put activity as a hedge against a further decline to this level. Delivery volumes have surged by 84.38% to 16.41 lakh shares on 23 March, signalling increased investor participation, yet the rally lacks the confirmation of a break above key moving averages. This technical backdrop supports the interpretation that put buyers are primarily seeking protection rather than outright bearish exposure. Could this be a tactical hedge in a volatile environment rather than a directional bet?

Delivery Volume and Market Participation

The recent rise in delivery volume to 16.41 lakh shares, an 84.38% increase over the five-day average, indicates strong investor engagement in the cash market. However, the stock’s inability to surpass key moving averages suggests that this participation is cautious. The put activity at strikes close to the current price aligns with this cautious stance, as investors may be seeking downside protection amid uncertainty. The thinning delivery-backed conviction in the rally could be a key reason for the surge in put buying, as market participants look to safeguard positions without necessarily signalling a bearish outlook.

Conclusion: Protective Hedging Most Likely, But Bearish Bets Present

The heavy put option activity at Rs 3,900 and Rs 4,000 strikes on Interglobe Aviation Ltd ahead of the 30 March expiry is best interpreted as a blend of protective hedging and some degree of bearish positioning. The stock’s recent gains and outperformance of the sector, combined with its position below all major moving averages, suggest that put buyers are primarily seeking to shield long positions from a potential pullback rather than aggressively betting on a sharp decline. The significant fresh positioning and open interest reinforce this view, while the proximity of the strikes to the current price and the 52-week low provide logical technical support levels for hedging. Put writing appears less likely given the high turnover and open interest, which point to net buying rather than premium collection. Should investors consider similar protective strategies or interpret this as a signal to reduce exposure?
