National Aluminium Company Ltd Gains 11.48%: 7 Key Factors Driving the Surge

2 March 2026: Strong Start Amid Market Weakness

National Aluminium Company Ltd began the week on a positive note, closing at Rs.362.80, up 2.24% from the previous close of Rs.354.85. This gain was notable as the Sensex declined by 1.41% to 35,812.02. The stock’s resilience in a falling market highlighted early investor confidence, supported by a volume of 7,72,423 shares. The broader market weakness contrasted with the stock’s strength, setting the tone for a bullish week ahead.

3 March 2026: Upgrade to Strong Buy Boosts Momentum

On 3 March, MarketsMOJO upgraded National Aluminium’s rating from 'Buy' to 'Strong Buy', citing robust fundamentals and technical indicators. The company’s exceptional quality metrics, including a zero debt profile, an average ROCE of 33.90%, and a half-year peak ROCE of 41.36%, underpinned this upgrade. The stock closed at Rs.362.80 (+2.24%), maintaining its upward trajectory despite the Sensex’s 1.41% decline. Institutional investor confidence, reflected in a 32.02% stake, further supported the positive outlook.

4 March 2026: Continued Gains Despite Market Pressure

Trading resumed on 4 March with the stock advancing 2.98% to close at Rs.373.60, outperforming the Sensex which fell 1.92% to 35,125.64. Volume increased to 8,52,862 shares, signalling sustained investor interest. The stock’s ability to gain amid a weakening benchmark index reinforced its status as a market outperformer. This day’s performance laid the groundwork for the significant rally that followed on 5 March.

5 March 2026: Record Intraday High and Exceptional Trading Activity

National Aluminium Company Ltd delivered its most remarkable performance on 5 March, surging 5.93% to close at Rs.395.75, with an intraday high of Rs.404.20 representing an 8.19% increase from the previous close. This gain outpaced the Aluminium & Aluminium Products sector’s 5.6% rise and the Sensex’s modest 1.29% gain. The stock’s volume exploded to over 4.1 million shares, with a traded value approximating ₹289.37 crores, placing it among the most actively traded stocks by value and volume.

Delivery volumes on 4 March surged by 197.23% compared to the five-day average, reaching 1.2 crore shares, indicating strong accumulation by institutional investors. The stock traded above all key moving averages, confirming a robust technical uptrend. This day also saw a surge in call option activity, with 6,571 contracts traded at the ₹400 strike price expiring 30 March 2026, generating a turnover of ₹3,824.32 lakhs. Open interest rose sharply by 14.44%, signalling fresh bullish positioning in derivatives markets.

Derivatives and Market Sentiment on 5 March

The sharp increase in open interest and call option volumes reflected heightened market optimism. The futures and options segments combined saw a derivatives value exceeding ₹2,62,259.5 lakhs, underscoring the stock’s prominence among traders. The weighted average price of traded shares skewed towards the day’s lower range, suggesting accumulation at attractive levels despite the strong price gains. This activity coincided with the stock’s inclusion in the MojoStocks thematic list and a Mojo Score upgrade to 80.0, reinforcing its strong buy status.

6 March 2026: Valuation Concerns Prompt Rating Downgrade

Despite continued strong financial performance and operational excellence, MarketsMOJO downgraded National Aluminium’s rating from 'Strong Buy' to 'Buy' on 5 March, citing valuation concerns. The company’s Price to Earnings ratio stood at 11.83, Price to Book at 3.66, and EV to EBITDA at 7.76, reflecting a 'very expensive' valuation grade. The PEG ratio remained low at 0.20, indicating earnings growth justifies some premium, but the elevated multiples suggested limited near-term upside.

The stock closed marginally lower at Rs.395.60 (-0.04%) on 6 March, with the Sensex declining 0.98% to 35,232.05. Despite the downgrade, National Aluminium’s fundamentals remained robust, with a 9-month PAT growth of 27.3% and a market capitalisation of ₹72,685 crores, second only to Hindalco Industries in the sector. The company’s return on capital employed (ROCE) and return on equity (ROE) remained exceptionally high at 41.36% and 30.82% respectively.

Weekly Price Performance: Stock vs Sensex

Key Takeaways

Positive Signals: National Aluminium’s 11.48% weekly gain significantly outperformed the Sensex’s 3.00% decline, driven by strong fundamentals, technical momentum, and institutional accumulation. The upgrade to 'Strong Buy' early in the week reflected exceptional operational metrics, including a zero debt profile, high ROCE, and consistent profit growth. Robust trading volumes and record derivatives activity underscored growing market interest and confidence.

Cautionary Notes: The downgrade to 'Buy' on 5 March highlighted valuation concerns, with the stock classified as 'very expensive' based on P/E, P/B, and EV multiples. Elevated valuation metrics suggest limited near-term upside and potential for increased volatility. Investors should monitor commodity price fluctuations and sector dynamics, as aluminium prices remain sensitive to global supply-demand factors.

Overall, National Aluminium Company Ltd demonstrated a compelling blend of growth, quality, and market leadership during the week, supported by strong investor participation and positive technical signals. The recent rating adjustment reflects a balanced view of valuation risks amid sustained operational excellence.
