Why is Cholaman.Inv.&Fn falling/rising?

As of 28-Jul, Cholamandalam Investment & Finance Company Ltd is experiencing a decline in its stock price, currently at 1,491.40, which reflects a decrease of 13.4 points or 0.89%. The stock has been on a downward trend, losing 5.25% over the past week and 9.74% over the past month. Despite this recent decline, the stock has shown strong long-term performance with a year-to-date increase of 25.69% and a remarkable 592.87% rise over the past five years. Today's performance indicates that the stock has outperformed its sector by 0.48%, although it has been falling for five consecutive days. The stock's moving averages suggest it is currently lower than the shorter-term averages but higher than the 200-day moving average. Additionally, rising investor participation is noted, with a significant increase in delivery volume, indicating some level of interest despite the price drop.
In the broader market context, Cholamandalam's recent short-term performance contrasts with the benchmark Sensex, which has declined by 1.59% over the past week and 3.77% over the past month. This suggests that while the stock is underperforming in the short term, it has still managed to outperform the benchmark in the same timeframe. The company's strong fundamentals, including a high return on equity and consistent positive results over the last ten quarters, support its long-term growth potential. However, the stock is considered expensive with a high price-to-book value, which may be contributing to the recent price decline as investors reassess its valuation against its peers.
