Why is Coromandel Inter falling/rising?

As of 12-Aug, Coromandel International Ltd's stock price is currently at Rs 2,399.20, reflecting a decline of Rs 40.1 or 1.64%. Today's price summary indicates that the stock has underperformed its sector by 2.07%, with an intraday low of Rs 2,347.95, marking a decrease of 3.74%. Over the past week, the stock has experienced a significant drop of 8.42%, although it has shown positive performance over the longer term, with a year-to-date increase of 27.62% and a one-year return of 38.14%. Despite its strong long-term fundamentals, including a high return on equity and healthy growth in net sales, the stock is facing pressure from falling investor participation, as evidenced by a 62.24% decline in delivery volume compared to the five-day average.
In the broader market context, while the Sensex has only decreased by 0.59% over the past week, Coromandel's performance has been notably weaker, indicating a divergence from the overall market trend. The stock's valuation appears expensive with a high price-to-book ratio, which may be contributing to investor caution. Additionally, despite strong institutional holdings and a solid growth outlook, the recent underperformance in the short term suggests that market sentiment may be shifting, leading to the current decline in stock price.
