Why is ASM Technologies falling/rising?

As of 01-Sep, ASM Technologies Ltd is experiencing a decline in its stock price, currently at 3,515.95, reflecting a decrease of 185.0 points or 5.0%. The stock has underperformed its sector today by 6.27% and has been on a downward trend for the last two days, with a total decline of 10.08%. It opened with a loss of 4.86% and reached an intraday low of Rs 3,515.95. Over the past week, the stock has fallen by 9.14%, contrasting with its strong performance over the past month, where it gained 29.97%. Despite its impressive long-term growth, including a 156.83% increase year-to-date and a 5876.97% rise over five years, the recent price movement indicates a significant short-term setback. The company has shown strong financial health with a low Debt to EBITDA ratio and impressive growth in net sales and operating profit, but the current valuation appears expensive, which may be contributing to the stock's recent decline.
In the broader market context, the stock's short-term performance has significantly lagged behind the benchmark, with the Sensex only declining by 1.56% over the past week. This stark contrast highlights the stock's recent struggles despite its historical outperformance against the BSE500 over longer periods. The falling investor participation, indicated by a 62.48% drop in delivery volume, suggests a lack of confidence among investors, which may be exacerbating the stock's decline. While the company has consistently reported positive results and strong growth metrics, the current market sentiment and valuation concerns are likely influencing the stock's negative trajectory in the short term.
