Rs 280 Puts — 3.9% Below Current Price — Draw 2,587 Contracts on Oil & Natural Gas Corporation Ltd.

Put Options Event and Cash Market Context

The 26 May 2026 expiry saw concentrated put option activity at the Rs 280 strike, with 2,587 contracts traded and an open interest of 1,972 contracts. The turnover for these puts was approximately Rs 113.5 lakhs, signalling notable liquidity and interest in this strike. Meanwhile, Oil & Natural Gas Corporation Ltd. outperformed its sector by 3.69% on the day, gaining 5.07% and touching an intraday high of Rs 295.50. The stock has been on a two-day winning streak, rising 4.62% over this period, and opened with a gap up of 2.1% on 12 May.

This juxtaposition of rising stock price and heavy put activity invites a closer look at the nature of the options trades — is this hedging, a bearish bet, or put writing?

Strike Price Analysis: Moneyness and Intent

The Rs 280 strike sits approximately 3.9% below the current underlying price of Rs 291.60, placing these puts out-of-the-money (OTM). OTM puts are often used as protective instruments, allowing holders of the underlying stock to hedge against a potential pullback without incurring the higher premiums associated with at-the-money (ATM) or in-the-money (ITM) puts.

Given the stock's recent rally and position above all major moving averages — including the 5-day, 20-day, 50-day, 100-day, and 200-day — the Rs 280 strike aligns closely with a technical support zone below the 50-day moving average. This suggests that the put activity may be aimed at protecting gains rather than signalling outright bearish conviction.

Alternatively, put writing at this strike could indicate a bullish stance, with sellers collecting premium under the assumption that the stock will remain above Rs 280 through expiry. However, the volume and open interest data point more towards fresh buying rather than predominantly selling.

Interpreting the Put Activity: Multiple Perspectives

Put option activity can be ambiguous. The three primary interpretations are:

• Protective Hedging: Investors holding long positions buy OTM puts to guard against downside risk during a rally.
• Bearish Positioning: Traders buy puts anticipating a decline, often at ATM or ITM strikes.
• Put Writing (Selling): Traders sell puts to collect premium, betting the stock will stay above the strike price.

In this case, the OTM nature of the Rs 280 puts combined with the stock’s strong upward momentum and position above all key moving averages supports the hedging interpretation as the most plausible. The stock’s 5.07% gain on the day and recent consecutive gains suggest confidence in the underlying, making a bearish bet less likely at this strike.

Put writing is a possibility, but the ratio of contracts traded (2,587) to open interest (1,972) indicates significant fresh buying rather than just premium collection. This fresh activity is consistent with investors seeking downside protection amid a rally — should investors consider similar hedging strategies?

Open Interest and Contracts Analysis

The open interest of 1,972 contracts relative to the 2,587 contracts traded on 12 May suggests that a substantial portion of the activity represents new positions rather than merely adjustments or rollovers. This fresh positioning indicates active interest in downside protection or speculative put buying rather than put selling, which typically shows higher open interest relative to volume.

Moreover, the turnover of Rs 113.5 lakhs at this strike is significant, reflecting meaningful premium flow into these puts. The ratio of traded contracts to open interest, approximately 1.31:1, supports the view of active accumulation of put positions rather than unwinding.

Cash Market Context: Momentum and Moving Averages

Oil & Natural Gas Corporation Ltd. is trading comfortably above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, signalling a strong technical uptrend. The stock’s recent 5.07% gain on 12 May outpaced the sector’s 1.38% rise and the Sensex’s decline of 0.70%, underscoring its relative strength.

However, delivery volumes tell a more nuanced story. On 11 May, delivery volume fell sharply by 67.53% compared to the 5-day average, dropping to 26.95 lakh shares. This decline in investor participation suggests the rally may lack robust conviction from long-term holders, which could explain why some investors are seeking downside protection through put options — is this a prudent move or a sign of caution?

Delivery Volume and Quality of Participation

The sharp fall in delivery volume amid a rising price indicates that the rally is not fully supported by strong buying from long-term investors. This thinning participation often prompts existing holders to hedge their positions, especially when the stock is near key support levels such as the Rs 280 strike.

Such hedging activity can be a rational response to a rally that may be vulnerable to profit-taking or short-term corrections, rather than a signal of impending decline. The high dividend yield of 4.9% at the current price further supports the attractiveness of holding the stock while managing risk.

Conclusion: Protective Hedging Most Likely

The combination of OTM put activity at Rs 280, fresh positioning indicated by the volume-to-open-interest ratio, and a rising stock price above all major moving averages strongly suggests that the put contracts traded on Oil & Natural Gas Corporation Ltd. are primarily protective hedges rather than outright bearish bets.

Put writing as a bullish strategy cannot be entirely ruled out, but the data leans towards investors seeking to safeguard recent gains amid a rally that lacks strong delivery-backed participation. The stock’s high dividend yield and large-cap status further support a cautious but constructive stance.

Given this nuanced picture, should investors consider hedging their positions in ONGC or view the rally as sustainable without downside protection?
