Why is Cummins India falling/rising?

As of 19-Sep, Cummins India Ltd. is currently priced at 4,090.00, reflecting a decrease of 11.35 points or 0.28%. The stock has been experiencing a slight decline, having fallen for the last two days with a total return of -0.79% during this period. Despite this recent downturn, the stock has shown strong performance over the longer term, with a 1-week return of 1.57%, a 1-month return of 9.07%, and a year-to-date increase of 24.70%. Additionally, it is trading above its moving averages, indicating a generally positive trend. However, there has been a notable drop in investor participation, with delivery volume falling by 47.56% against the 5-day average, which may contribute to the recent price decline. The company's strong fundamentals, including a healthy return on equity and consistent sales growth, suggest long-term strength, but its high valuation relative to peers raises concerns.
In the broader market context, Cummins India's recent performance has outpaced the Sensex, which has only gained 0.88% over the past week. This indicates that while the stock is facing short-term challenges, it has been able to deliver superior returns compared to the benchmark over longer periods, including a 240.42% increase over the last three years. The stock's high institutional ownership at 40.14% suggests confidence from knowledgeable investors, yet the expensive valuation and high PEG ratio could be causing caution among retail investors. Overall, while the stock has strong long-term prospects, the recent price movement reflects a combination of declining investor participation and concerns over valuation.
