Why is Health.Global falling/rising?

As of 18-Sep, Healthcare Global Enterprises Ltd is experiencing a decline in its stock price, currently at 657.00, which reflects a decrease of 14.65 or 2.18%. The stock has underperformed its sector by 2.07% today and has been on a downward trend for the last three days, accumulating a total loss of 3.31% during this period. It opened with a significant loss of 3.51% and reached an intraday low of Rs 633.3, marking a decline of 5.71%. Despite a strong performance over the past year with a return of 58.29%, the company has faced challenges, including a 24.9% drop in profits, a high Debt to EBITDA ratio of 3.91 times, and a concerning increase in pledged promoter shares, which now account for 88% of holdings.
In the broader market context, the stock's short-term performance has been notably weaker compared to the Sensex, which has gained 1.80% over the past week, while Healthcare Global has declined by 4.21%. This underperformance is compounded by a significant drop in investor participation, with delivery volume falling by 84.68% against the five-day average. Although the stock has shown strong long-term performance, outperforming the BSE500 over various time frames, the recent negative financial results and high levels of pledged shares have contributed to a bearish sentiment among investors, leading to the current decline in stock price.
