Indian Oil Corporation Gains 4.22%: 6 Key Factors Driving the Week’s Momentum

29 December 2025: Open Interest Surge Signals Renewed Bullish Sentiment

Indian Oil Corporation Ltd kicked off the week with a notable 10.3% increase in open interest in its derivatives segment, rising from 37,835 to 41,730 contracts. This surge accompanied a 1.22% gain in the stock price to ₹162.00, outperforming the Sensex which declined 0.41% to 37,140.23. The derivatives turnover value reached ₹95,071 lakhs, highlighting strong liquidity and active participation from institutional and retail investors.

Despite subdued delivery volumes and mixed moving average trends, the stock reversed a three-day losing streak, signalling a potential trend reversal. The price remained below short- and medium-term moving averages but comfortably above longer-term averages, indicating a solid base for further gains. The 5% dividend yield added to the stock’s appeal amid this renewed market interest.

30 December 2025: Rating Downgrade Reflects Mixed Technical Signals

On 30 December, MarketsMOJO downgraded IOC’s rating from Strong Buy to Buy, reflecting a more cautious stance amid mixed technical indicators despite strong fundamentals. The stock price slipped 0.31% to ₹161.50, slightly underperforming the Sensex which was nearly flat at 37,135.83.

Fundamentally, IOC remained robust with a 14.63% CAGR in net sales and a 28.19% operating profit margin. Quarterly results showed a 105.8% increase in PAT to ₹7,817.55 crores and a strong operating profit to interest ratio of 7.16 times. Valuation metrics remained attractive with a PEG ratio of 0.2 and a dividend yield near 4.9%.

Technically, the downgrade was driven by a shift to mildly bullish signals, with weekly MACD turning mildly bearish and RSI neutral. The stock traded below its 52-week high but maintained a large-cap status with institutional holdings at 37.7%, underscoring confidence despite the rating adjustment.

31 December 2025: Intraday High and Open Interest Surge Amid Bullish Momentum

IOC surged 3.03% intraday to a high of ₹166.10, closing at ₹166.45 (+3.07%), outperforming the Sensex’s 0.83% gain. The oil sector also advanced 2.02%, but IOC’s outperformance highlighted strong investor interest. The stock traded above all key moving averages, signalling a bullish technical setup.

Open interest in derivatives rose sharply by 14.58% to 30,208 contracts, with futures volume at 25,606 contracts and a combined futures and options value exceeding ₹44,872.66 lakhs. Delivery volumes increased by 25.01% to 59.94 lakh shares, indicating rising investor confidence.

This surge in open interest and volume, combined with price appreciation, suggested fresh long positions and bullish positioning. The stock’s market capitalisation rose to ₹2,34,596.13 crores, and the dividend yield remained attractive at 4.95%.

1 January 2026: Technical Upgrades Support Bullish Momentum

IOC continued its positive momentum on 1 January, closing at ₹165.80, a slight dip of 0.39% from the previous day but maintaining a strong technical posture. The stock’s price touched ₹167.25 intraday, nearing its 52-week high of ₹174.45.

Technical indicators upgraded the trend from mildly bullish to bullish. The monthly MACD turned bullish, while weekly MACD remained mildly bearish, signalling potential for sustained rallies after short-term consolidation. RSI remained neutral, providing room for further gains without overbought risk.

Daily moving averages were firmly bullish, supported by bullish Bollinger Bands on weekly and monthly charts. On-Balance Volume (OBV) was mildly bullish weekly and bullish monthly, confirming accumulation. Dow Theory showed a mildly bearish weekly trend but a mildly bullish monthly trend, reflecting mixed but generally positive momentum.

2 January 2026: Technical Momentum Moderates to Mildly Bullish

On the final trading day of the week, IOC’s stock closed at ₹166.80, up 0.60%, with technical momentum shifting from bullish to mildly bullish. The stock traded within a moderate range, with a high of ₹168.10 and a low of ₹164.90, reflecting some consolidation after the recent rally.

Weekly MACD turned mildly bearish, while monthly MACD remained bullish, indicating a short-term pause within a longer-term uptrend. RSI signals were neutral, and Bollinger Bands suggested contained volatility. The Know Sure Thing (KST) indicator was bullish weekly but mildly bearish monthly, and Dow Theory showed a mildly bearish weekly trend with no clear monthly trend.

On-Balance Volume was mildly bullish weekly but neutral monthly, suggesting cautious accumulation. Despite the technical moderation, IOC’s returns over one week (+4.22%) and longer periods remained strong relative to the Sensex, reinforcing its status as a resilient large-cap oil sector stock.

Key Takeaways

Positive Signals: The week saw strong derivatives market activity with open interest surging over 10% twice, signalling fresh directional bets. The stock outperformed the Sensex by nearly 3% for the week, supported by robust fundamentals including a 14.63% CAGR in net sales, a 28.19% operating margin, and a high dividend yield near 5%. Technical upgrades from mildly bullish to bullish on key indicators such as monthly MACD and Bollinger Bands reinforced the positive momentum. Institutional holdings remain strong at 37.7%, adding stability.

Cautionary Notes: The downgrade from Strong Buy to Buy reflects mixed technical signals, with weekly MACD and Dow Theory indicators showing mild bearishness or neutrality. Delivery volumes showed some variability, and the stock’s price remains below its 52-week high of ₹174.45, indicating resistance levels to watch. The technical momentum softened to mildly bullish by week’s end, suggesting potential consolidation or cautious trading ahead.

Conclusion

Indian Oil Corporation Ltd demonstrated a resilient and broadly positive performance during the week ending 2 January 2026, with a 4.22% gain that outpaced the Sensex’s 1.35% rise. The stock’s strong fundamentals, attractive valuation, and active derivatives market participation underpin a constructive outlook. However, mixed technical signals and a recent rating downgrade to Buy advise a measured approach as the stock navigates near-term resistance and potential consolidation phases.

Investors should monitor open interest trends, volume patterns, and key technical levels such as the 52-week high near ₹174.45 to assess the sustainability of the current momentum. The combination of solid financial metrics and evolving technical indicators positions IOC as a noteworthy large-cap stock within the oil sector, balancing growth potential with prudent risk management considerations.
