Why is National Plastic falling/rising?

As of 17-Sep, National Plastic Technologies Ltd's stock price is currently at Rs 290.00, reflecting an increase of Rs 10.25 or 3.66%. The stock has shown strong performance recently, gaining 22.57% over the past week and outperforming its sector by 4.27%. It has been on a consecutive gain streak for the last five days, with an intraday high of Rs 304.8. Additionally, the stock is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a positive trend. Despite a year-to-date decline of 29.22%, the company has demonstrated healthy long-term growth with net sales increasing at an annual rate of 36.24%. However, it faces challenges with a high Debt to EBITDA ratio of 3.72 times, which raises concerns about its ability to service debt.
Broader market context shows that while National Plastic has outperformed the Sensex in the short term, with a 22.57% return over the past week compared to the Sensex's 1.56%, it has underperformed over the last year, with a return of -24.48% against the market's -0.46%. This disparity highlights the stock's volatility and the impact of its debt levels on investor sentiment. The company’s attractive valuation, trading at a discount compared to peers, and rising investor participation may provide some support for the stock's recent gains, but the overall negative performance over the past year remains a significant concern for potential investors.
