Why is National Plastic falling/rising?

As of 03-Sep, National Plastic Technologies Ltd is experiencing a decline in its stock price, currently at Rs. 223.75, which reflects a decrease of -1.15 (-0.51%). The stock has hit a new 52-week low of Rs. 217.5 today and has underperformed its sector by -1.13%. Over the past three days, the stock has consistently fallen, totaling a decline of -3.64%. In the context of its recent performance, the stock has shown a significant drop of -8.58% over the past month and -41.12% over the past year, while its profits have increased by 8.5%. Despite a healthy long-term growth rate in net sales and an attractive valuation, the high Debt to EBITDA ratio of 3.72 times raises concerns about the company's ability to service its debt, contributing to the stock's downward movement.
In the broader market context, the stock's short-term performance has been slightly worse than the benchmark, with a -0.31% return over the past week compared to the Sensex's -0.27%. The overall market has generated negative returns of -4.38% in the last year, but National Plastic's decline has been significantly steeper at -41.12%. This underperformance indicates that investor sentiment towards the stock is weak, compounded by the company's recent flat results and ongoing challenges in servicing its debt. The rising investor participation, however, suggests some interest in the stock, but it remains overshadowed by the negative factors affecting its price.
