Why is National Plastic falling/rising?

As of 28-Aug, National Plastic Technologies Ltd is experiencing a decline in its stock price, currently at Rs 221.85, which reflects a decrease of Rs 2.6 or 1.16%. The stock has been underperforming recently, having fallen for the last two consecutive days, resulting in a total drop of 5.19%. It is also trading close to its 52-week low, just 1.94% away from Rs 217.55. Over the past week, the stock has decreased by 2.29%, and its performance over the last month shows a significant decline of 9.08%. Despite a healthy long-term growth rate in net sales of 36.24% and a positive return on capital employed (ROCE) of 16.5, the stock's ability to service debt is a concern due to a high Debt to EBITDA ratio of 3.72 times. Additionally, the stock has underperformed the market significantly over the past year, with a return of -43.41% compared to the BSE500's -5.01%.
In the broader market context, the stock's recent performance is slightly better than the benchmark index, the Sensex, which has fallen by 2.34% over the past week. However, the stock's year-to-date performance shows a stark contrast, with a decline of 45.85% compared to the Sensex's gain of 2.48%. The falling investor participation, indicated by a 28.94% drop in delivery volume, further suggests a lack of confidence among investors. The stock is also trading below all its moving averages, indicating a bearish trend. While the company has shown some long-term growth potential, the current financial challenges and recent performance trends are contributing to the stock's downward movement.
