Why is Cummins India falling/rising?

As of 25-Aug, Cummins India Ltd. is currently priced at Rs. 3,869.35, reflecting a decrease of Rs. 52.65 or 1.34%. The stock has recently hit a new 52-week high of Rs. 3,933.55 but has underperformed its sector by 0.86% today. After three consecutive days of gains, the stock has experienced a trend reversal. Despite trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, there has been a decline in investor participation, with delivery volume falling by 1.22% against the 5-day average. Over the past week, the stock has gained 2.25%, and it has shown strong performance over the last month and year-to-date, with returns of 9.92% and 17.97%, respectively.
In the broader market context, Cummins India has outperformed the Sensex, which has only increased by 0.45% over the past week. The company's strong long-term fundamentals, including a healthy average return on equity of 20.76% and significant growth in net sales and operating profit, support its valuation. However, the stock is considered expensive with a high price-to-book value and a PEG ratio of 3.1, which may be contributing to the recent price decline. Additionally, high institutional holdings at 40.14% indicate confidence from larger investors, but the recent drop in delivery volume suggests some caution among retail investors.
