Why is QMS Medical falling/rising?

As of 05-Sep, QMS Medical Allied Services Ltd is experiencing a price increase, with its current price at 93.40, reflecting a rise of 3.35 or 3.72%. The stock has outperformed its sector today by 1.88%, and its performance over the past week shows a gain of 5.12%, while it has risen by 21.85% over the past month. However, despite these positive short-term movements, the stock has underperformed over the longer term, with a year-to-date decline of 17.67% and a one-year drop of 25.49%. The stock is trading below its 200-day moving average, although it is above its shorter-term moving averages, indicating mixed signals. Additionally, there has been a notable decrease in investor participation, with delivery volume falling by 30.49% against the five-day average.
In the broader market context, the stock's recent performance contrasts sharply with the benchmark Sensex, which has only increased by 1.29% over the past week and 0.36% over the past month. While QMS Medical has shown strong operating profit growth at an annual rate of 30.17%, its overall return over the past year remains significantly negative compared to the market. The company's attractive valuation, indicated by a PEG ratio of 1.6 and a return on capital employed (ROCE) of 13.1, suggests potential for long-term growth. However, the flat results reported in June and the substantial decline in stock price relative to the market underscore the challenges it faces, leading to a cautious outlook despite recent gains.
