Why is QMS Medical falling/rising?

As of 08-Oct, QMS Medical Allied Services Ltd is experiencing a price increase, currently at 107.15, reflecting a change of 1.85 or 1.76% upward. The stock has shown a strong performance over the past week with a return of +6.09%, significantly outpacing the Sensex, which only increased by +0.84%. However, despite this recent uptick, the stock has underperformed its sector by -0.66% today, and there has been a decline in investor participation, with delivery volume falling by -1.23% against the 5-day average. On a longer-term basis, while the stock has generated a return of -6.83% over the past year, it has seen a healthy growth in operating profit at an annual rate of 30.17%, indicating potential for future appreciation.
Broader Market Context: In the context of the broader market, QMS Medical's recent short-term performance is notably stronger than the Sensex, which has only gained +0.84% over the same week. Additionally, the stock is trading at a discount compared to its peers' average historical valuations, which may attract more institutional investors, who have increased their stake by 1.6% in the last quarter. This growing interest from institutional investors, who typically have more resources to analyze company fundamentals, could provide further support for the stock's price movement. However, the flat results reported in June and the significant growth in interest expenses may raise concerns among investors, potentially impacting future performance.
