Robust Call Option Volumes Signal Investor Optimism
On 12 August 2026, National Aluminium Company Ltd emerged as one of the most actively traded stocks in the call options segment, with four strike prices attracting substantial interest. The strike price of ₹420 saw the highest number of contracts traded at 16,006, generating a turnover of ₹3319.24 lakhs and an open interest of 3,325 contracts. This was closely followed by the ₹400 strike, which recorded 8,490 contracts traded and a turnover of ₹3016.60 lakhs, with open interest standing at 1,720 contracts.
Other notable strike prices included ₹410 and ₹440, with 8,539 and 8,120 contracts traded respectively, and turnovers of ₹2343.96 lakhs and ₹764.30 lakhs. The underlying stock price at the time was ₹419.35, placing the ₹420 strike marginally out-of-the-money, while the ₹400 and ₹410 strikes were comfortably in-the-money, indicating a strong preference for bullish call positions.
Expiry Patterns and Market Positioning
All the active call options are set to expire on 25 August 2026, suggesting that traders are positioning themselves for a potential price move within the next two weeks. The concentration of open interest at the ₹420 strike price, which is just above the current market price, highlights a consensus expectation that National Aluminium’s shares will breach this level before expiry.
The elevated open interest at in-the-money strikes such as ₹400 and ₹410 further underscores confidence in sustained upward momentum. This pattern is typical of investors seeking leveraged exposure to anticipated gains while managing risk through strike price selection.
Stock Performance and Technical Strength
National Aluminium Company Ltd has demonstrated strong price action recently, outperforming its sector by 3.72% on the day and registering a 7.01% gain. The stock has been on a three-day winning streak, delivering a cumulative return of 9.84%. It opened the trading session with an 8.07% gap up and touched an intraday high of ₹419.70, reflecting robust buying interest.
Technically, the stock is trading above all major moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling a sustained uptrend. The narrow intraday trading range of ₹1.5 suggests consolidation near recent highs, often a precursor to further directional moves.
Sectoral Context and Investor Participation
The Aluminium & Aluminium Products sector has gained 4.19% on the day, with National Aluminium outpacing this benchmark. Delivery volumes have risen by 9.5% compared to the five-day average, with 40.02 lakh shares changing hands on 11 August 2026, indicating rising investor participation and conviction.
Liquidity remains healthy, with the stock’s average traded value supporting trade sizes of up to ₹5.41 crore, making it accessible for institutional and retail investors alike.
Fundamental and Market Ratings
National Aluminium Company Ltd holds a mid-cap market capitalisation of ₹71,243 crore and operates within the non-ferrous metals industry. The company’s MarketsMOJO score stands at 72.0, reflecting a positive outlook, and it was recently upgraded from a Hold to a Buy rating on 3 June 2026. This upgrade aligns with the improving fundamentals and technical strength observed in recent months.
Additionally, the stock offers a dividend yield of 3.35%, providing an attractive income component alongside capital appreciation potential.
Implications for Investors
The surge in call option activity at strike prices near and above the current market level suggests that traders are positioning for a breakout beyond ₹420 in the coming weeks. Given the stock’s strong technical setup, sectoral tailwinds, and improving fundamental ratings, this bullish positioning appears well-founded.
Investors considering exposure to National Aluminium should monitor open interest trends and price action closely, particularly as the 25 August expiry approaches. The combination of rising delivery volumes and sustained gains indicates robust demand, but the narrow trading range also calls for vigilance regarding potential volatility.
Overall, the data points to a positive near-term outlook for National Aluminium Company Ltd, with call option market activity serving as a valuable barometer of investor sentiment and expectations.
