Why is MPL Plastics falling/rising?

As of 11-Sep, MPL Plastics Ltd is experiencing a decline in its stock price, currently at 9.14, reflecting a decrease of 0.13 or 1.4%. The stock has underperformed its sector by 2.24% today and is trading below all its moving averages, including the 5-day, 20-day, 50-day, 100-day, and 200-day averages. Additionally, there has been a significant drop in investor participation, with delivery volume falling by 54.14% compared to the 5-day average. Over the past year, the stock has generated a return of -35.18%, and its financial health is concerning, as indicated by a negative book value and a high debt-to-equity ratio, which contribute to its weak long-term fundamental strength.
In the broader market context, MPL Plastics' short-term return of +0.99% over the past week is slightly lower than the Sensex's return of +1.03%. However, the company's long-term performance has been significantly poorer, with a year-to-date decline of 25.51% compared to the Sensex's gain of 4.36%. The stock's consistent underperformance against the benchmark over the last three years, along with flat results and negative EBITDA, suggests that it is viewed as a risky investment. This combination of factors contributes to the stock's downward movement and reflects a lack of confidence among investors.
