Why is Global Health falling/rising?

As of 20-Aug, Global Health Ltd's stock price is currently at 1,377.30, reflecting an increase of 6.55 (0.48%). The stock has been gaining momentum, having risen 2.55% over the last two days, and it is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. However, it underperformed its sector by 0.38% today, and there has been a notable decline in investor participation, with delivery volume falling by 34.1% against the 5-day average. Despite these mixed signals, the company boasts a high return on equity (ROE) of 15.90%, a low debt-to-equity ratio, and strong long-term growth in operating profit, which has grown at an annual rate of 33.58%. These positive factors contribute to the stock's resilience and upward movement.
In the broader market context, Global Health's performance over the past week shows a return of 1.65%, slightly outperforming the Sensex, which returned 1.64%. Over the past month, the stock has significantly outperformed the benchmark with a return of 4.54% compared to the Sensex's 0.12%. Despite the stock trading at a premium valuation, its ability to generate a 27.37% return over the past year, while the broader market has seen negative returns, indicates strong investor confidence. The high institutional holdings at 23.74% further suggest that knowledgeable investors are backing the stock, which may help sustain its upward trajectory despite the recent decline in trading volume.
