Why is Plastiblends (I) falling/rising?

As of 24-Sep, Plastiblends India Ltd is currently priced at 193.30, reflecting an increase of 1.25 (0.65%). Today's performance indicates a trend reversal as the stock has gained after two consecutive days of decline, outperforming its sector by 0.72%. However, the stock has shown a negative return of -1.25% over the past week and a significant decline of -40.52% over the last year, indicating consistent underperformance against the benchmark. The company has a low Debt to Equity ratio of 0.03, which is a positive factor, but it also faces challenges such as poor long-term growth, with operating profit declining at an annual rate of -4.28% over the past five years. Additionally, the stock is trading at a premium compared to its peers, and its profits have decreased by -16.5% over the past year.
In the broader market context, the Sensex has experienced a slight decline of -1.18% over the past week, which is slightly better than Plastiblends' performance. While the stock has outperformed the sector today, its year-to-date return of -20.29% starkly contrasts with the Sensex's positive return of +4.58%. This underperformance is compounded by a significant drop in investor participation, with delivery volume falling by -51.22% compared to the five-day average. Overall, despite today's slight increase, the stock's long-term outlook remains concerning, as evidenced by its consistent underperformance against the benchmark and declining financial metrics.
