Why is Prudent Corp falling/rising?

As of 26-Sep, Prudent Corporate Advisory Services Ltd is experiencing a decline in its stock price, currently at Rs 2,574.80, reflecting a decrease of Rs 210.9 or 7.57%. Today's price summary indicates that the stock has underperformed its sector by 6.04%, with an intraday low of Rs 2,544.05, marking an 8.67% drop. The stock has shown high volatility today, with an intraday volatility of 5.23%. Over the past week, the stock has decreased by 13.16%, while it has fallen 9.33% over the last month, contrasting with a positive return of 3.75% over the past year. Despite strong long-term fundamentals, including a high average return on equity of 31.29% and consistent positive results over the last 12 quarters, the stock's valuation appears expensive with a price-to-book ratio of 16, which may be contributing to the recent price decline.
In the broader market context, the stock's short-term performance has significantly lagged behind the benchmark, with the Sensex only declining by 2.66% over the past week. This underperformance is further highlighted by the stock's negative returns in both the one-week and one-month periods compared to the benchmark's relatively stable performance. While the company has demonstrated strong long-term growth and high institutional holdings, the current market sentiment may be influenced by concerns over its valuation compared to peers, leading to the observed price drop.
