Why is Eicher Motors falling/rising?

As of 22-Sep, Eicher Motors Ltd is currently priced at Rs 6,953.05, reflecting a decrease of Rs 19.45 or 0.28%. The stock has recently underperformed its sector by 0.53% and has experienced a trend reversal after two consecutive days of gains. Despite this decline, Eicher Motors has shown strong performance over various time frames, with a 1-week return of 2.21%, a 1-month return of 17.23%, and a year-to-date return of 44.09%. The company benefits from low debt and strong long-term fundamentals, evidenced by a healthy growth rate in net sales and operating profit. However, it is trading at a premium valuation compared to its peers, which may contribute to the current price movement.
In the broader market context, Eicher Motors has outperformed the Sensex, which has only gained 0.46% over the past week, while Eicher's returns have been significantly higher over the past year at 39.95% compared to the Sensex's decline of 2.82%. The stock's liquidity remains strong, with rising investor participation indicated by increased delivery volumes. However, the company's flat results in June and high valuation metrics, such as a PEG ratio of 2.5, may be causing some caution among investors, contributing to the recent price decline despite its overall strong performance.
