Surge in Put Option Volumes and Open Interest
On 27 July 2026, ONGC’s put options with a strike price of ₹245 expiring on 28 July saw the highest trading activity among stock options. A total of 2,705 contracts changed hands, generating a turnover of ₹87.03 lakhs. Open interest in these contracts stands at 1,108, indicating sustained interest from market participants looking to either hedge downside risk or speculate on further declines.
The underlying stock price closed at ₹242.61, slightly below the ₹245 strike, which makes these puts attractive for protective strategies or bearish bets. The concentration of activity at this strike price suggests that traders are positioning for a potential drop below this level in the near term.
Price Performance and Technical Context
ONGC’s stock has underperformed its sector by 2.22% on the day, closing with a 2.44% loss compared to a marginal 0.06% gain in the oil sector index. Over the past two trading sessions, the stock has declined by 3.35%, signalling a short-term downtrend. Intraday lows touched ₹242.59, reinforcing the proximity to the put strike price where option activity is concentrated.
Technically, the stock is trading above its 20-day moving average but remains below its 5-day, 50-day, 100-day, and 200-day moving averages. This mixed moving average alignment points to a weakening momentum, with short- and medium-term trends still bearish. The recent drop in delivery volume by 36.83% compared to the five-day average suggests waning investor participation, which could exacerbate volatility.
Investor Sentiment and Hedging Implications
The heavy put option activity at the ₹245 strike price is indicative of investors seeking downside protection or expressing bearish views. Given the stock’s large-cap status and a market capitalisation of ₹3,12,934 crores, institutional investors often use options to hedge sizeable equity exposures. The elevated open interest in puts may reflect such risk management strategies amid uncertain oil price dynamics and global economic concerns.
Moreover, ONGC’s current dividend yield of 5.54% remains attractive, but the recent downgrade in its Mojo Grade from Buy to Hold on 23 July 2026, with a Mojo Score of 58.0, signals a more cautious outlook from analysts. This downgrade aligns with the observed bearish positioning in the options market, suggesting that investors are factoring in potential near-term headwinds.
Expiry Patterns and Market Implications
The expiry date of 28 July 2026 is critical as it represents the imminent settlement of these put contracts. The clustering of open interest and volume at the ₹245 strike price may lead to increased price sensitivity around this level in the final trading sessions before expiry. Market makers and traders often adjust their hedges dynamically, which can amplify price swings.
Investors should monitor the stock’s price action closely in the coming days, as a breach below ₹245 could trigger further downside pressure, potentially validating the bearish sentiment embedded in the options market. Conversely, a rebound above this level might see put option sellers closing positions, which could alleviate some selling pressure.
Comparative Sector and Market Context
While ONGC has lagged the oil sector and broader Sensex indices recently, the sector itself remains volatile amid fluctuating crude oil prices and geopolitical uncertainties. The stock’s liquidity, with a 5-day average traded value supporting trade sizes of approximately ₹5.32 crores, ensures that option market movements are reflective of genuine investor interest rather than illiquidity distortions.
Given the stock’s large-cap stature and strategic importance in India’s energy sector, the observed option market dynamics provide valuable insights into institutional sentiment and risk appetite. The combination of technical weakness, reduced investor participation, and concentrated put option activity suggests a cautious stance prevailing among market participants.
Outlook and Investor Considerations
Investors holding ONGC shares should consider the implications of the heightened put option activity as a signal of potential near-term downside risk or increased volatility. Those with existing long positions might explore protective strategies such as buying puts or employing collars to mitigate losses. Conversely, traders with a bearish outlook may view the current option market positioning as an opportunity to capitalise on expected weakness.
It is also prudent to keep an eye on upcoming corporate announcements, crude oil price movements, and macroeconomic indicators that could influence ONGC’s fundamentals and market sentiment. The recent downgrade to a Hold rating by analysts underscores the need for a measured approach in portfolio allocation.
Summary
In summary, the surge in put option trading at the ₹245 strike price ahead of the 28 July expiry highlights a growing bearish bias and hedging activity in Oil & Natural Gas Corporation Ltd. The stock’s recent underperformance, technical challenges, and reduced investor participation reinforce this cautious outlook. Market participants should remain vigilant to price movements around this critical level as expiry approaches, adjusting their strategies accordingly to manage risk and capitalise on potential opportunities.
