Why is Aarti Drugs falling/rising?

As of 26-Sep, Aarti Drugs Ltd is experiencing a decline in its stock price, currently at Rs 470.00, which reflects a decrease of Rs 36.4 or 7.19%. The stock has underperformed its sector by 4.85% today and has been on a downward trend for the past two days, accumulating a total loss of 9.2%. Additionally, the stock has shown a negative performance over the past week, with a decline of 10.47%, while its one-year return stands at -9.19%. Despite a high management efficiency indicated by a return on capital employed (ROCE) of 17.84% and a low debt-to-equity ratio of 0.45, the stock is trading at a discount compared to its peers, which may not be sufficient to counteract the recent price drops.
In the broader market context, the Sensex has also faced a decline of 2.66% over the past week, indicating a challenging environment for stocks in general. However, Aarti Drugs' performance has been notably worse than the benchmark, suggesting specific issues affecting the company. The pharmaceuticals and drugs sector as a whole has decreased by 2.34%, reflecting broader sectoral weakness. Furthermore, the falling investor participation, with a significant drop in delivery volume, indicates a lack of confidence among investors, contributing to the stock's downward movement.
