Why is EMS falling/rising?

As of 13-Aug, EMS Ltd's stock price is currently at Rs 552.35, reflecting a decline of Rs 28.65 or 4.93%. The stock has underperformed significantly, with a 1-week return of -8.06% and a 1-month return of -8.31%. Today's performance indicates that the stock opened with a loss of 3.61% and touched an intraday low of Rs 551, which is only 0.43% away from its 52-week low. Additionally, EMS is trading below all its moving averages, and there has been a notable drop in investor participation, with delivery volume falling by 41.05% compared to the 5-day average. The company's recent financial results have also been disappointing, with a decline in profit before tax and profit after tax compared to previous quarters, contributing to a negative sentiment around the stock.
In the broader market context, EMS Ltd's performance contrasts sharply with the Sensex, which has seen a slight decline of only 0.01% over the past week. The stock's year-to-date performance is particularly concerning, showing a drop of 35.02%, while the benchmark has gained 3.07%. Despite the company having a low debt-to-equity ratio and healthy long-term growth in net sales, the overall underperformance in both the short and long term, along with a lack of confidence from domestic mutual funds, suggests that investors are wary of the stock's valuation and future prospects. This combination of factors has led to a continued decline in EMS Ltd's stock price.
