Why is Astal Lab falling/rising?

As of 29-Jul, Astal Laboratories Ltd is experiencing a decline in its stock price, currently at Rs 91.46, reflecting a decrease of Rs 1.76 or 1.89%. The stock has underperformed its sector today, with a consecutive fall over the last two days resulting in a total decline of 2.94%. Additionally, the stock has seen a significant drop in delivery volume, which fell by 55.9% compared to the 5-day average. Despite a strong performance over the past year, generating a return of 22.22%, the stock has faced a short-term setback, with a 4.23% decline over the past week.
In the broader market context, the Sensex has only decreased by 1.03% over the same week, indicating that Astal Laboratories Ltd is underperforming relative to the benchmark. While the company has shown impressive growth in operating profit and has consistently declared positive results over the last five quarters, the recent price movement suggests that investor participation is waning. The stock's liquidity remains adequate, but the falling delivery volume may signal a lack of confidence among investors, contributing to its recent decline.
