The forecasted Q1 sales and gross margin indicate a stable financial outlook for ASML, which is likely to maintain investor confidence in the short term. However, the expectation that 2024 sales will be similar to 2023 suggests that there may not be significant growth in the immediate future, which could temper investor enthusiasm. The company's preparation for growth in 2025 is a positive sign, but it is a longer-term prospect and may not have an immediate impact on the stock price.
