Why is Aster DM Health. falling/rising?

As of 22-Sep, Aster DM Healthcare Ltd is experiencing a decline in its stock price, currently at 647.80, which reflects a decrease of 3.45 or 0.53%. Despite this recent drop, the stock has shown strong performance over various periods, with a 4.60% increase over the past week and a remarkable 53.98% rise over the last year. The stock is currently trading close to its 52-week high, being only 4.07% away from Rs 674.15. However, the company has faced challenges, including negative results for the last three consecutive quarters, with net sales declining by 44.99% and a significant drop in profit after tax by 94.9%. Additionally, the company has a high Debt to EBITDA ratio and a low return on capital employed, which raises concerns about its long-term fundamental strength.
In the broader market context, Aster DM Healthcare's short-term performance has outpaced the benchmark Sensex, which has only increased by 0.46% over the past week. While the stock has shown strong returns in the long term, it is important to note that 40.67% of promoter shares are pledged, which could exert additional downward pressure in a falling market. The combination of strong recent performance metrics, alongside significant operational challenges and high debt levels, creates a complex picture for investors, contributing to the current price movement.
