Why is ASM Technologies falling/rising?

As of 03-Sep, ASM Technologies Ltd's stock price is currently at 3,513.95, reflecting an increase of 160.4, or 4.78%. Today's price summary indicates that the stock has outperformed its sector by 5.33% and has experienced a trend reversal, gaining after three consecutive days of decline. The stock reached an intraday high of Rs 3,521.2, showcasing a 5% increase. Over the past month, the stock has risen by 29.89%, and its year-to-date performance shows an impressive gain of 156.68%. Positive factors contributing to this rise include the company's strong ability to service debt, as indicated by a low Debt to EBITDA ratio of 1.28 times, and significant growth in net sales and operating profit. However, the stock is considered expensive with a high Enterprise value to Capital Employed ratio, which could pose a risk to its valuation.
In the broader market context, ASM Technologies has significantly outperformed the benchmark Sensex, which has seen a minimal decline of 0.27% over the past week, while ASM's stock has dropped by 8.81% in the same period. Despite this recent short-term decline, the stock's long-term performance remains robust, generating a return of 132.70% over the past year compared to the Sensex's decline of 2.41%. This strong performance, coupled with rising investor participation and liquidity, suggests that the stock is well-positioned for continued growth, despite some valuation concerns.
