Why is ASM Technologies falling/rising?

As of 31-Jul, ASM Technologies Ltd is experiencing a decline in its stock price, currently at Rs 2,832.00, which reflects a decrease of Rs 29.0 or 1.01%. Today's price summary indicates that the stock opened with a significant loss of 3.88% and reached an intraday low of Rs 2,722, marking a drop of 4.86%. The stock has underperformed its sector by 0.41%, and the delivery volume has decreased by 42.66% compared to the 5-day average, suggesting a reduction in investor participation. Despite a strong long-term performance, with a year-to-date return of 106.87% and a remarkable 523.72% increase over the past three years, the current price movement reflects concerns over its high valuation and low domestic mutual fund interest, which may indicate a lack of confidence at current price levels.
In the broader market context, ASM Technologies' recent performance contrasts with the benchmark Sensex, which has seen a decline of only 1.22% over the past week. While the stock has shown impressive returns over longer periods, its short-term performance has been negative, particularly in the last week where it has underperformed the benchmark. The company's strong ability to service debt and consistent profit growth are positive factors; however, the high valuation metrics and lack of domestic mutual fund investment raise caution among investors, contributing to the stock's current downward trend.
