Why is EMS falling/rising?

As of 03-Sep, EMS Ltd's stock price is currently at Rs 541.00, reflecting an increase of Rs 5.0 or 0.93%. The stock has been gaining for the last four days, with a total return of 1.69% during this period, and it has outperformed its sector by 1.11%. However, the stock has experienced a significant decline over the past month, down 10.71%, and a year-to-date drop of 36.35%. Despite a healthy long-term growth rate in net sales of 40.80%, the company reported flat results for June 25, with a decline in profit before tax and profit after tax compared to previous quarters. Additionally, the stock is trading at a high valuation with a Price to Book Value of 3.1, which may deter some investors, especially given the low domestic mutual fund ownership of only 1.03%.
In the broader market context, EMS Ltd's short-term performance has been relatively weak compared to the benchmark, with a 1-week return of -1.19% against the Sensex's -0.27%. This underperformance is consistent with the stock's longer-term trends, as it has generated a return of -34.57% over the past year, significantly lagging behind the Sensex's gain of 3.11% in the same timeframe. The stock's liquidity appears adequate, but the overall sentiment may be influenced by its recent financial performance and the lack of confidence from domestic mutual funds, which could contribute to the stock's volatility and price movements.
