Why is EMS falling/rising?

As of 09-September, EMS Ltd's stock price is currently at 569.55, reflecting a decrease of 2.05, or 0.36%. The stock has been underperforming, having fallen consecutively for the last two days with a total decline of 1.09%. In terms of returns, EMS has shown a 6.26% increase over the past week, but it has a disappointing performance over the last month and year, with declines of 1.95% and 29.14%, respectively. Despite a healthy long-term growth in net sales at an annual rate of 40.80% and a low debt-to-equity ratio, the stock's overall performance has been below par, leading to its recent price decline.
Broader market context indicates that while EMS has outperformed the Sensex by 6.26% over the past week, it has significantly lagged behind the benchmark in the longer term, with a year-to-date return of -32.99% compared to the Sensex's 3.79%. This underperformance in both the near and long term, coupled with falling investor participation and liquidity issues, suggests a lack of confidence among investors. The stock's current price movement reflects these broader trends, indicating a challenging environment for EMS Ltd amidst a generally improving market.
