Why is Polyplex Corpn falling/rising?

As of 02-Sep, Polyplex Corporation Ltd is experiencing a decline in its stock price, currently at 1,015.15, which reflects a decrease of 8.5 or 0.83%. The stock has underperformed its sector today by 1.54% and is close to its 52-week low, being only 2.28% away from that point. Over the past week, the stock has dropped by 0.96%, and it has seen a significant decline of 21.74% year-to-date. The company's operating profit has suffered a substantial annual decline of 35.79% over the last five years, and recent quarterly results have shown a negative PAT of Rs -19.31 crore, indicating poor financial health. Additionally, 99.94% of promoter shares are pledged, which can exert further downward pressure on the stock price in a declining market.
In the broader market context, the Sensex has shown a slight decline of 0.78% over the past week, indicating a generally weak market environment. However, Polyplex's performance has been notably worse, with consistent underperformance against the benchmark over the last three years, including a return of -15.29% in the past year compared to the Sensex's positive return of 2.58%. The stock's liquidity appears adequate for trading, but the falling investor participation, with a 48.26% drop in delivery volume, suggests waning interest among investors. Overall, the combination of poor financial results, high promoter share pledging, and persistent underperformance relative to the market contributes to the stock's downward trajectory.
