Why is ASM Technologies falling/rising?

As of 29-Aug, ASM Technologies Ltd is experiencing a decline in its stock price, currently at Rs 3,700.95, which represents a decrease of Rs 209.05 or 5.35%. Today's price summary indicates that the stock has underperformed its sector by 4.67%, touching an intraday low of Rs 3,700.95. The trading volume has also shown a significant drop, with delivery volume falling by 55.37% against the 5-day average. Despite a strong long-term performance, with a year-to-date increase of 170.34% and a 1-year return of 149.09%, the stock's current decline may be influenced by its higher valuation metrics and falling investor participation.
In the broader market context, the stock's short-term performance has been less favorable compared to the benchmark, with a 1-week return of -2.38% against the Sensex's -1.84%. While ASM Technologies has demonstrated strong growth in net sales and operating profit, its high valuation and recent price drop may be causing some investor hesitation. The company's ability to service debt remains strong, but the recent decline in delivery volume and the stock's performance relative to the benchmark suggest that market sentiment may be shifting, leading to the current price movement.
