Why is National Plastic falling/rising?

As of 23-Sep, National Plastic Technologies Ltd is experiencing a decline in its stock price, currently at Rs 292.95, which reflects a decrease of Rs 8.0 or 2.66%. The stock has underperformed its sector by 1.41% today and has been on a downward trend for the last two days, resulting in a total drop of 7.47%. Despite a strong performance over the past month with a return of 28.85%, the stock has struggled year-to-date with a decline of 28.50%. The company has shown healthy long-term growth with net sales increasing at an annual rate of 36.24%, but it also faces challenges such as a high Debt to EBITDA ratio of 3.72 times, which indicates a low ability to service its debt.
In the broader market context, while the Sensex has shown a slight decline of 0.34% over the past week, National Plastic's recent performance has been significantly worse, particularly in the last year where it has underperformed the market with a return of -20.38% compared to the BSE500's -4.69%. This underperformance, coupled with falling investor participation and a significant drop in delivery volume, suggests a lack of confidence among investors. The stock's attractive valuation relative to peers may not be enough to offset concerns regarding its debt levels and recent flat results, contributing to the current price decline.
