Why is Astral falling/rising?

As of 18-Aug, Astral Ltd's stock price is currently at 1,313.00, reflecting an increase of 34.1 points or 2.67%. Today's price summary indicates that the stock reached an intraday high of Rs 1342.55, which is a rise of 4.98%. However, despite this uptick, the stock has shown a negative performance over the past week, down 5.01%, and has significantly underperformed over the past month and year, with declines of 12.89% and 30.51%, respectively. Positive factors contributing to the stock's movement include high management efficiency, a low debt-to-equity ratio, and healthy long-term growth in net sales and operating profit. Conversely, negative results from the latest quarter, including a substantial drop in profit after tax and low returns on capital employed, have raised concerns about the stock's valuation and performance.
In the broader market context, while Astral Ltd's stock has risen today, it has been underperforming compared to the Sensex, which has gained 0.83% over the past week. The stock's recent price movement is somewhat in line with the plastic products sector, which has increased by 2.82%. However, the overall trend shows that Astral has lagged behind the benchmark indices over longer periods, with significant declines in both short-term and long-term returns. This underperformance, coupled with the stock's high valuation relative to its peers, suggests that while there may be short-term gains, the long-term outlook remains cautious.
