Why is QMS Medical falling/rising?

As of 19-Sep, QMS Medical Allied Services Ltd is currently priced at 108.35, reflecting an increase of 2.45 or 2.31%. The stock has shown strong performance in the short term, with a 1-week return of +18.42% and a 1-month return of +36.98%, significantly outperforming the Sensex, which returned +0.85% and +1.39% respectively during the same periods. However, there is a noted decline in investor participation, with delivery volume falling by 36.82% compared to the 5-day average. Despite this, the stock is trading above all key moving averages, indicating positive momentum. The company has demonstrated healthy long-term growth, with operating profit increasing at an annual rate of 30.17%, and it is trading at a discount compared to its peers, which may attract investors.
In the broader market context, while QMS Medical has underperformed over the past year with a return of -16.30% compared to the Sensex's -0.35%, its recent short-term gains suggest a potential recovery phase. The stock's performance today has outpaced the sector by 4.5%, indicating a positive shift in market sentiment. Despite the flat results reported in June and the significant growth in interest expenses, the company's rising profits and attractive valuation metrics, such as a PEG ratio of 1.8, may be contributing to the stock's upward movement in the short term.
