Why is National Plastic falling/rising?

As of 01-Sep, National Plastic Technologies Ltd is experiencing a decline in its stock price, currently at Rs 226.00, which reflects a decrease of Rs 6.2 or 2.67%. The stock has underperformed its sector by 4.33% today and opened with a significant loss of 6.09%. It has also touched an intraday low of Rs 218.05, indicating a bearish trend. Over the past week, the stock has fallen by 3.42%, and its year-to-date performance shows a substantial decline of 44.84%. While the company has reported a healthy long-term growth in net sales at an annual rate of 36.24%, the stock's negative performance is exacerbated by a high Debt to EBITDA ratio of 3.72 times, indicating a low ability to service debt. Additionally, the stock is trading below all key moving averages, which suggests a lack of bullish momentum.
In the broader market context, the Sensex has only declined by 1.56% over the past week, highlighting that National Plastic's short-term performance is significantly worse than the benchmark. The stock's year-on-year return of -42.54% starkly contrasts with the broader market's decline of just 2.43%. This underperformance is further compounded by a drastic drop in investor participation, with delivery volume falling by 90.2% against the 5-day average. Despite the company's profits rising by 8.5% over the past year, the overall market sentiment and the company's financial challenges have led to a negative outlook, contributing to the stock's current downward trajectory.
