Why is Cummins India falling/rising?

As of 20-Aug, Cummins India Ltd. is experiencing a price increase, with its current price at Rs 3,818.90, reflecting a rise of Rs 68.9 or 1.84%. The stock has shown strong performance today, outperforming its sector by 0.37% and reaching an intraday high of Rs 3,833.9. It is also trading above all key moving averages, indicating positive momentum. Over the past week, the stock has gained 0.71%, and it has significantly outperformed the benchmark Sensex over the past month with an increase of 8.26% compared to the Sensex's 0.12%. The company benefits from strong long-term fundamentals, including a healthy return on equity (ROE) of 20.76% and impressive growth in net sales and operating profit. However, it faces challenges due to its high valuation, as indicated by a PEG ratio of 3 and a price-to-book value of 14, which suggests it is trading at a premium compared to its peers.
In the broader market context, while Cummins India has shown a positive return of 1.84% today, the Sensex has increased by 1.64% over the same period, indicating that the stock is performing slightly better than the overall market. Despite a decline in investor participation, with delivery volume falling by 10.34% against the 5-day average, the stock remains liquid enough for trading. The high institutional holdings at 40.14% suggest confidence from larger investors, which may contribute to the stock's upward movement. Overall, the combination of strong fundamentals and positive short-term performance relative to the benchmark supports the stock's rising price.
