Why is Cummins India falling/rising?

As of 26-Aug, Cummins India Ltd. is experiencing a decline in its stock price, currently at Rs 3,829.60, which reflects a decrease of Rs 39.75 or 1.03%. The stock has been under pressure, having fallen consecutively for the last two days, resulting in a total drop of 2.36% during this period. Despite this recent downturn, the stock has shown positive performance over the longer term, with a 1-week return of 2.12% and a 1-month return of 8.80%. It is also close to its 52-week high, just 2.71% away from Rs 3,933.55. However, the stock's liquidity appears to be affected, as the delivery volume has decreased significantly by 37.1% compared to the 5-day average.
In the broader market context, while Cummins India has outperformed its sector by 0.66% today, the overall market sentiment appears to be weak, as indicated by the Sensex's decline of 1.05% over the past week. The company's strong long-term fundamentals, including a healthy return on equity and significant growth in net sales, suggest potential for recovery. However, the stock is currently viewed as expensive, trading at a premium compared to its peers, which may be contributing to the recent selling pressure. The high institutional ownership indicates confidence from knowledgeable investors, yet the stock's recent performance and valuation concerns may be causing hesitation among retail investors.
