Why is EMS falling/rising?

As of 10-Sep, EMS Ltd's stock price is currently at 565.00, reflecting a decrease of 4.55, or 0.8%. The stock has been underperforming recently, having fallen for three consecutive days with a total decline of 1.88%. Additionally, the stock's performance today has lagged behind its sector by 1.91%. Over the past week, EMS Ltd has shown a modest gain of 4.44%, but it has experienced a decline of 2.74% over the past month and a significant drop of 33.53% year-to-date. The company's recent financial results have been disappointing, with a notable decrease in profit before tax and profit after tax compared to previous quarters. Despite a healthy long-term growth rate in net sales, the stock's valuation appears expensive relative to its return on equity and price-to-book value, which may contribute to investor caution.
In the broader market context, EMS Ltd's short-term performance has outpaced the Sensex, which gained 1.06% over the past week. However, the stock's longer-term returns have been concerning, with a 29.74% decline over the past year, contrasting sharply with the Sensex's slight decrease of 0.61% during the same period. This underperformance in both the short and long term, combined with falling investor participation and liquidity issues, suggests a challenging environment for EMS Ltd, leading to its current price decline.
