Why is National Plastic falling/rising?

As of 04-Jul, National Plastic Technologies Ltd is currently priced at 270.00, experiencing a decline of 3.95, or 1.44%. The stock has underperformed its sector by 1.3% today, with an intraday low of Rs 266.5, reflecting a decrease of 2.72%. Over the past week, the stock has dropped by 3.21%, while it has shown a significant decline of 34.10% year-to-date and 32.47% over the past year. Despite a positive return of 10.20% over the last month, the stock's performance is overshadowed by a high Debt to EBITDA ratio of 3.72 times, indicating a low ability to service debt. Additionally, the stock is trading at a discount compared to its peers, but the falling investor participation, with a delivery volume decrease of 84.26% against the 5-day average, suggests waning interest among investors.
In the broader market context, the Sensex has only declined by 0.74% over the past week, indicating that National Plastic's short-term performance is significantly worse than the benchmark. The stock's negative returns of -32.47% over the past year starkly contrast with the Sensex's positive return of 4.23%, highlighting its underperformance in the market. While the company has shown a profit increase of 7.4% over the past year, the overall sentiment remains negative due to flat operating results and a low operating profit to interest ratio. This combination of factors contributes to the stock's current downward movement.
