Why is Polyplex Corpn falling/rising?

As of 08-Sep, Polyplex Corporation Ltd is experiencing a decline in its stock price, currently at 1,031.00, reflecting a decrease of 3.0 points or 0.29%. The stock has shown mixed performance in recent periods, with a 1-week return of +0.72%, but a significant 1-month decline of -8.75%. It is currently trading close to its 52-week low, just 3.78% above that level. Despite outperforming its sector by 0.4% today, the stock's long-term outlook is concerning, with a poor operating profit growth rate of -35.79% over the last five years and negative quarterly results indicating substantial losses. Additionally, 99.94% of promoter shares are pledged, which can exert downward pressure on the stock in a declining market.
In the broader market context, the Sensex has shown a modest gain of 0.53% over the past week, while Polyplex's performance has been notably weaker over the longer term, with a year-to-date return of -20.51% compared to the Sensex's +3.39%. This consistent underperformance against the benchmark, coupled with the company's high valuation relative to peers and the significant pledge of promoter shares, contributes to a negative sentiment surrounding the stock. The liquidity of the stock remains adequate, but the overall financial health and growth prospects appear to be weighing heavily on investor confidence.
