Why is Cummins India falling/rising?

As of 02-Sep, Cummins India Ltd. is currently priced at Rs 3,835.35, reflecting a decrease of Rs 44.65 or 1.15%. The stock has recently underperformed its sector by 0.34% and has fallen after two consecutive days of gains. Despite being close to its 52-week high, the stock's delivery volume has decreased significantly, indicating a decline in investor participation. Over the past week, Cummins India has shown a modest increase of 0.15%, while its performance over the last month has been more robust at 7.62%. The company has demonstrated strong long-term fundamentals, with a healthy return on equity and consistent growth in net sales and operating profit. However, it is also facing challenges due to its high valuation compared to peers, as indicated by its price-to-book ratio and a relatively high PEG ratio.
In the broader market context, Cummins India has outperformed the Sensex over various periods, including a year-to-date return of 16.93% compared to the Sensex's 2.58%. This suggests that while the stock has been performing well overall, recent price movements may be influenced by market sentiment and liquidity issues. The decline in delivery volume could signal a shift in investor confidence, despite the company's strong fundamentals and institutional support. Overall, the stock's recent price drop can be attributed to a combination of short-term market dynamics and concerns regarding its valuation amidst strong long-term performance indicators.
