Rs 270 and Rs 275 Puts Draw Significant Interest on Oil & Natural Gas Corporation Ltd. Ahead of June Expiry

Put Options Event and Cash Market Context

On 27 May 2026, the put options market for Oil & Natural Gas Corporation Ltd. saw concentrated activity at strikes Rs 270, Rs 275, and Rs 280. The Rs 280 strike led with 2,188 contracts traded, followed by Rs 270 and Rs 275 with 1,375 and 1,153 contracts respectively. Turnover was substantial, with Rs 415.99 lakhs at Rs 280, Rs 161.88 lakhs at Rs 275, and Rs 137.05 lakhs at Rs 270. Open interest (OI) figures show Rs 280 strike holding 1,906 contracts, Rs 270 at 671, and Rs 275 at 414, indicating a mix of fresh and existing positions.

The underlying stock price at Rs 278.75 has declined 3.13% on the day, underperforming its sector by 2.3%, and touched an intraday low of Rs 275.5, with volume weighted towards the lower price range. Delivery volumes have fallen by nearly 25% compared to the five-day average, suggesting reduced investor participation despite the price dip. The stock remains above its 100-day and 200-day moving averages but below its 5-day, 20-day, and 50-day averages, signalling a mixed technical picture — is this a temporary pullback or a sign of deeper weakness?

Strike Price Analysis: Moneyness and Intent

The Rs 270 and Rs 275 put strikes lie approximately 3.2% and 1.1% below the current price, respectively, placing them slightly out-of-the-money (OTM) and near-the-money (NTM). The Rs 280 strike is just above the current price, making it in-the-money (ITM). This distribution is critical for interpreting the put activity. OTM puts, especially when the stock is near or above these strikes, often indicate hedging rather than outright bearish bets. Conversely, ITM puts can signal directional bearishness or complex spread strategies.

Given the stock’s recent decline and the proximity of these strikes to the current price, the Rs 280 puts may reflect protective positioning or speculative bearishness. The Rs 270 and Rs 275 strikes, being slightly below the market price, could be used as downside protection by holders of long positions or as put writing targets by bullish traders expecting the stock to hold above these levels — which scenario fits best here?

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

Put option activity is inherently ambiguous. The Rs 280 ITM puts, with the highest turnover and OI, suggest some degree of bearish conviction or protective hedging. However, the stock’s position above its long-term moving averages and the relatively modest decline of 3.13% on the day complicate a purely bearish interpretation.

Meanwhile, the Rs 270 and Rs 275 strikes, with significant contracts traded but lower OI, indicate fresh positioning. The fact that these strikes are OTM and the stock remains above them suggests that some investors may be hedging existing long holdings against a potential pullback to support levels near these strikes. Alternatively, put writing at these strikes could be a bullish strategy, collecting premium with the expectation that the stock will not fall below these levels by expiry.

Open Interest and Contracts: Fresh Positioning vs Existing Exposure

The ratio of contracts traded to open interest provides insight into whether the activity represents fresh positioning or adjustments to existing positions. For the Rs 280 strike, 2,188 contracts traded against an OI of 1,906 suggests a moderate turnover, possibly a mix of new and rolling positions. The Rs 270 strike shows 1,375 contracts traded versus 671 OI, indicating significant fresh activity. The Rs 275 strike’s 1,153 contracts against 414 OI also points to new positions being established.

This fresh activity at strikes just below the current price aligns with hedging or put writing strategies rather than outright bearish bets, especially given the stock’s technical context. The relatively lower OI at these strikes compared to the Rs 280 strike suggests that the market is still building or adjusting positions ahead of the 30 June expiry.

Cash Market Context: Technicals and Delivery Volumes

The stock’s technical setup is nuanced. It trades above its 100-day and 200-day moving averages, which often serve as long-term support, but remains below its shorter-term 5-day, 20-day, and 50-day averages, indicating recent weakness. This mixed picture suggests a consolidation phase rather than a clear downtrend.

Delivery volumes have declined by nearly 25% compared to the five-day average, signalling reduced conviction among investors during the recent price dip. This thinning participation may be why some investors are seeking downside protection through puts — should this be interpreted as caution or a prelude to further weakness?

Fundamental and Sector Overview

Oil & Natural Gas Corporation Ltd. remains a large-cap heavyweight in the oil sector with a market capitalisation of Rs 3,50,172.07 crores. The stock offers a high dividend yield of 4.79% at current prices, which can be attractive for income-focused investors. Despite recent underperformance relative to its sector and the broader Sensex, the company’s fundamentals remain robust, supported by its scale and strategic importance in the energy space.

Conclusion: Protective Hedging Most Likely, But Bearish Bets Present

The put option activity in Oil & Natural Gas Corporation Ltd. ahead of the 30 June expiry reveals a nuanced picture. The concentration of contracts at strikes Rs 270 and Rs 275, slightly below the current price, combined with fresh open interest and a stock trading above long-term moving averages, suggests that much of the put activity is likely protective hedging by long holders rather than outright bearish speculation.

However, the significant volume and open interest at the Rs 280 ITM strike indicate some degree of bearish positioning or speculative protection against near-term weakness. The declining delivery volumes and recent price underperformance add a layer of caution, but the overall technical and fundamental context does not support a strong bearish conviction.

Investors and traders might consider whether the put activity signals prudent risk management or a subtle warning of further downside — should you be hedging your position in Oil & Natural Gas Corporation Ltd. too, or does the data suggest the rally has more room?
