Why is Krishana Phosch. falling/rising?

As of 28-Aug, Krishana Phoschem Ltd's stock price is currently at 581.40, reflecting a decrease of 6.35, or 1.08%. Today's price summary indicates that the stock has outperformed its sector by 2.27%, although it is experiencing a decline in investor participation, with delivery volume falling by 66.62% against the 5-day average. Over the past week, the stock has decreased by 2.03%, while it has shown strong performance over the longer term, with a 134.96% return over the past year and a remarkable 190.21% year-to-date increase. The company has demonstrated healthy long-term growth, with net sales and operating profit growing significantly, and has consistently reported positive results for the last five quarters. However, the stock is considered very expensive based on its valuation metrics, which may be contributing to the recent price decline.
In the broader market context, the stock's short-term performance has been slightly better than the benchmark, as the Sensex has declined by 2.32% over the same week. Despite the recent drop in price, institutional investors are increasing their stake in the company, indicating confidence in its fundamentals. This could suggest that while the stock is currently facing downward pressure, the long-term outlook remains positive due to strong financial performance and institutional interest. However, the high valuation and declining investor participation may be causing some caution among retail investors, impacting the stock's immediate price movement.
