Why is Centrum Capital falling/rising?

As of 25-Aug, Centrum Capital Ltd is experiencing a decline in its stock price, currently at Rs 38.15, which reflects a decrease of 1.56 (-3.93%). Today's price summary indicates that the stock has underperformed its sector by 3.74% and has fallen after two consecutive days of gains, touching an intraday low of Rs 38.1. The stock's performance over the past week shows a slight decline of 0.78%, while it has seen a modest increase of 0.34% over the past month. However, the company faces significant challenges, including a weak long-term fundamental strength with an average Return on Equity (ROE) of 0%, a high debt-equity ratio, and a very expensive valuation compared to its peers. Additionally, 45.24% of promoter shares are pledged, which can exert further downward pressure in a falling market.
In the broader market context, the Sensex has increased by 0.45% over the past week, contrasting with Centrum Capital's decline. This underperformance relative to the benchmark highlights the stock's struggles amidst a generally positive market environment. While the stock has shown a year-to-date return of 15.40%, the recent negative factors, including flat quarterly results and a significant pledge of promoter shares, contribute to investor concerns and may lead to continued selling pressure.
