Why is Aster DM Health. falling/rising?

As of 31-Oct, Aster DM Healthcare Ltd is experiencing a decline in its stock price, currently at 678.05, which represents a decrease of 19.65 or 2.82%. The stock has underperformed its sector by 1.55% today and has seen a consecutive fall over the last two days, resulting in a total decline of 3.05%. Despite a strong performance over the past year with a return of 53.16%, the company has reported negative results for the last three consecutive quarters, with significant declines in both profit after tax and net sales. Additionally, the stock's long-term fundamental strength is weak, evidenced by a negative compound annual growth rate in operating profits and a high debt-to-EBITDA ratio, which raises concerns about its ability to service debt.
In the broader market context, the stock's short-term performance has been notably weaker than the benchmark, with a 1-week return of -4.05% compared to the Sensex's -0.32%. While Aster DM Healthcare has shown strong returns over longer periods, such as 31.99% year-to-date and 174.07% over three years, the recent downturn is compounded by falling investor participation and a significant drop in delivery volume. The high percentage of pledged promoter shares further adds to the downward pressure on the stock price, particularly in a declining market.
