Why is Natl. Aluminium falling/rising?

As of 23-Sep, National Aluminium Company Ltd's stock price is currently at 208.85, reflecting a decrease of 2.05, or 0.97%. The stock has been underperforming recently, having fallen for the last three days with a total decline of 2.31%. Today's performance indicates that it has underperformed its sector by 0.72%. Over the past week, the stock has decreased by 3.49%, while it has shown a positive return of 10.53% over the past month. Despite these recent declines, the company has demonstrated strong fundamentals, including a high return on equity (ROE) of 17.57%, a low debt-to-equity ratio, and consistent positive results over the last seven quarters, which may support a more favorable long-term outlook.
Broader market context shows that while National Aluminium's short-term performance has been negative, the benchmark Sensex has only declined by 0.34% over the same week. This suggests that the stock's recent struggles are more pronounced compared to the broader market. However, the company has outperformed the benchmark over longer periods, with a 15.83% return over the past year compared to the Sensex's decline of 3.33%. The high institutional holdings at 30.82% indicate confidence among larger investors, which may provide some stability despite the recent price drop. Overall, while the stock is facing short-term challenges, its strong fundamentals and historical performance suggest potential for recovery.
