Why is Aster DM Health. falling/rising?

As of 15-Sep, Aster DM Healthcare Ltd is experiencing a decline in its stock price, currently at Rs 619.30, which reflects a decrease of Rs 12.2 or 1.93%. The stock has underperformed its sector by 1.75% today and has been on a consecutive downward trend for the last three days, accumulating a total drop of 3.69%. Despite a strong long-term performance, with a 48.92% return over the past year, the company has faced significant challenges recently, including negative results for the last three consecutive quarters, a decline in net sales by 44.99%, and a drastic fall in profit after tax by 94.9%. Additionally, the company's weak long-term fundamental strength, indicated by a negative CAGR growth in operating profits and a high debt-to-EBITDA ratio, further contributes to the stock's downward movement.
In the broader market context, Aster DM Healthcare's short-term performance has been notably weaker than the benchmark, with a 1-week return of -2.53% compared to the Sensex's gain of 1.24%. This underperformance is compounded by falling investor participation, as evidenced by a significant drop in delivery volume. The stock's liquidity remains adequate, but the high percentage of pledged promoter shares adds pressure in a declining market. Overall, while the company has shown strong long-term returns, the recent negative financial results and fundamental weaknesses are driving the stock's current decline.
