Why is ASM Technologies falling/rising?

As of 02-Sep, ASM Technologies Ltd is experiencing a decline in its stock price, currently at 3,353.55, reflecting a decrease of 162.4 points or 4.62%. The stock has been underperforming recently, having fallen consecutively for the last three days, resulting in a total decline of 14.23% during this period. It opened with a loss of 5% today and reached an intraday low of Rs 3340.2. Despite a strong long-term performance, with a year-to-date increase of 144.96% and a remarkable 5600.89% rise over the past five years, the stock's recent performance has been negatively impacted by a significant drop in investor participation, as evidenced by a 42.11% decrease in delivery volume compared to the five-day average.
In the broader market context, ASM Technologies has underperformed the Sensex, which has only declined by 0.78% over the past week, while the stock itself has dropped by 12.97% in the same timeframe. This stark contrast highlights the stock's recent struggles despite its strong long-term growth metrics, such as a 394.48% increase in PAT over the last six months and consistent positive results for five consecutive quarters. However, the stock's high valuation, indicated by a ROCE of 16.8 and a PEG ratio of 0.3, raises concerns among investors, contributing to its current downward trend.
