28 September: Death Cross Formation and Heavy Put Option Activity
On 28 September 2026, National Aluminium’s stock price declined sharply by 2.93% to close at Rs.348.00, underperforming the Sensex’s 1.60% drop. This day marked the formation of a Death Cross, a significant technical indicator where the 50-day moving average crossed below the 200-day moving average. This crossover is widely interpreted as a warning of a potential bearish trend, signalling weakening price momentum and a shift in investor sentiment towards caution.
The Death Cross coincided with heightened put option activity, as National Aluminium emerged as the most actively traded stock in the put options segment. A notable 10,725 put contracts were traded at the 340 strike price expiring the following day, with a turnover of approximately ₹3.58 crores. The stock closed just above this strike at Rs.346.80, indicating market participants were positioning for further downside or hedging existing long positions. This surge in put options reflected growing bearish sentiment amid the stock’s technical deterioration and recent underperformance relative to the broader market and sector peers.
Technically, the stock was trading below all key moving averages, reinforcing the bearish outlook. The decline in delivery volumes by nearly 69% compared to the 5-day average further suggested waning investor conviction. Despite these short-term headwinds, National Aluminium’s market capitalisation remained robust at ₹63,511 crores, and the company continued to offer an attractive dividend yield of 3.21%.

29 September: Downgrade to Hold Amid Mixed Technical and Valuation Signals
Following the technical developments, MarketsMOJO downgraded National Aluminium’s investment rating from 'Buy' to 'Hold' on 29 September 2026. This decision reflected a comprehensive reassessment of the company’s quality, valuation, financial trends, and technical indicators. While the company’s fundamentals remained strong, with an average Return on Equity of 20.50%, net-debt-free status, and record quarterly net sales of ₹5,302.38 crores, valuation concerns tempered enthusiasm. The stock’s Price to Book ratio of 3 was considered elevated, suggesting limited upside from current levels despite a PEG ratio of 0.5 indicating undervaluation relative to growth.
Technically, the downgrade was driven by a shift in momentum indicators. The Moving Average Convergence Divergence (MACD) turned mildly bearish on weekly and monthly charts, daily moving averages weakened, and Bollinger Bands showed bearish weekly readings. However, some indicators such as the Know Sure Thing (KST) and Dow Theory remained mildly bullish on monthly timeframes, highlighting a mixed technical landscape. The stock closed the day at Rs.348.00, down 2.93% from the previous close, continuing the downward trend initiated earlier in the week.
Despite the downgrade, National Aluminium’s long-term performance remained impressive, with a 1-year return of 73.57% and a 10-year return of 650.00%, vastly outperforming the Sensex. The downgrade thus reflected a cautious near-term stance rather than a fundamental shift in the company’s prospects.
Technical Momentum Shifts Amid Mixed Market Signals
On 29 September, the stock’s technical momentum shifted from mildly bullish to mildly bearish, reflecting the evolving market environment. The daily moving averages turned bearish, and the MACD indicator suggested weakening momentum. The Relative Strength Index (RSI) remained neutral, indicating neither overbought nor oversold conditions, while Bollinger Bands presented a divergence with bearish weekly but mildly bullish monthly signals.
The Know Sure Thing (KST) indicator offered some optimism, showing mild bullishness weekly and outright bullishness monthly, suggesting underlying momentum may still support the stock over the medium term. Dow Theory assessments echoed this mixed view, with weekly trends mildly bearish but monthly trends mildly bullish. On-Balance Volume (OBV) showed no clear trend, indicating volume did not confirm price movements decisively.
This complex technical picture suggests that while short-term price action faces headwinds, the longer-term uptrend remains intact. Investors were advised to monitor key support levels around Rs.348.00 closely, as a sustained break below could confirm bearish momentum, whereas a rebound might signal a resumption of the prior uptrend.

1. Technical Warning Signs: The formation of the Death Cross and bearish MACD signals indicate a shift towards a cautious near-term outlook, with potential for further downside or consolidation.
2. Elevated Put Option Activity: Heavy put option volumes at the 340 strike price reflect increased hedging and bearish sentiment, highlighting market participants’ concerns about further price declines.
3. Downgrade to Hold: The investment rating downgrade reflects a balanced view, acknowledging strong fundamentals but tempered by valuation concerns and weakening technical momentum.
4. Mixed Technical Momentum: While short-term indicators are bearish, some medium- and long-term signals remain mildly bullish, suggesting the stock’s longer-term uptrend is intact despite recent weakness.
Conclusion
National Aluminium Company Ltd’s week was characterised by a notable decline of 6.79%, underperforming the Sensex’s 3.20% fall. The emergence of the Death Cross and heavy put option activity signalled increased bearish sentiment and technical caution. The downgrade from Buy to Hold by MarketsMOJO further underscored the need for a measured approach, balancing the company’s robust fundamentals and attractive dividend yield against near-term technical headwinds and elevated valuation metrics.
Investors should closely monitor key support levels and technical indicators in the coming weeks to gauge whether the current momentum shift represents a temporary correction or a more sustained change in trend. Despite the short-term challenges, National Aluminium’s impressive long-term returns and market position continue to offer a foundation for potential recovery once technical conditions improve.
