Why is Escorts Kubota falling/rising?

As of 15-Sep, Escorts Kubota Ltd's stock is currently priced at 3,634.55, reflecting a decline of 53.1 points or 1.44%. The stock has been underperforming, having fallen consecutively for the last two days with a total decline of 1.67%. Additionally, the stock's performance today has underperformed its sector by 0.56%. In terms of returns, the stock has seen a decrease of 3.53% over the past week, although it has gained 6.89% over the past month. Despite positive operating cash flow and a low debt-to-equity ratio, the stock is facing challenges due to an expensive valuation and a recent drop in investor participation, with delivery volume falling significantly. Broader market context shows that while the stock has struggled in the short term, it has outperformed the benchmark Sensex over longer periods, with a year-to-date return of 9.26% compared to the Sensex's 4.67%. However, the recent decline in the stock's price contrasts with the Sensex's gain of 1.24% over the past week, indicating a divergence in performance. This underperformance may be attributed to the stock's high price-to-book value and a relatively low return on equity, which could be causing investor hesitation despite the company's strong fundamentals and positive historical performance.
