Why is Aster DM Health. falling/rising?

As of 04-Sep, Aster DM Healthcare Ltd is experiencing a price increase, currently at Rs 636.00, reflecting a rise of 15.5 points or 2.5%. The stock has shown strong performance today, outperforming its sector by 1.63%, and reached an intraday high of Rs 639, which is a 2.98% increase. Over the past week, the stock has gained 7.49%, and it has also performed well over the last month and year, with returns of 8.61% and 56.32%, respectively. Despite these positive movements, the company faces challenges, including weak long-term fundamental strength indicated by a -0.19% CAGR growth in operating profits over the last five years and negative results for the last three consecutive quarters, which may temper investor enthusiasm.
Broader Market Context: In comparison to the benchmark Sensex, which has only increased by 0.80% over the past week, Aster DM Healthcare's performance has significantly outpaced the market. This trend continues in the longer term, where the stock has achieved a year-to-date return of 23.81% against the Sensex's 3.30%. However, the stock's high debt-to-EBITDA ratio of 2.71 times and the fact that 40.67% of promoter shares are pledged could pose risks, especially in a volatile market. While the stock has shown impressive returns, the underlying financial weaknesses may lead to cautious sentiment among investors.
