Why is Global Health falling/rising?

As of 04-Aug, Global Health Ltd is experiencing a decline in its stock price, currently at 1,316.30, which reflects a decrease of 21.2 points or 1.59%. The stock has underperformed its sector by 0.37% today and has seen a trend reversal after two consecutive days of gains. Additionally, the stock's performance over the past week shows a decline of 2.63%, while it has performed well over the past month with an increase of 11.17%. Despite a high management efficiency indicated by a return on equity (ROE) of 15.90% and a low debt-to-equity ratio, the stock's recent movement is affected by falling investor participation, as evidenced by a 2.61% decrease in delivery volume against the five-day average.
In the broader market context, the stock's short-term performance contrasts with the benchmark, as the Sensex has gained 0.16% over the past week. While Global Health has outperformed the market with a year-to-date return of 21.54% compared to the Sensex's 3.69%, the recent decline suggests a shift in investor sentiment. The stock's liquidity remains adequate for trading, but the recent drop in delivery volume may indicate a cautious approach from investors, potentially influenced by the overall market's negative performance of -2.34% in the last year.
