Based on the latest data from August 2025, ASML is trading at $742.62, positioning the stock in the "undervalued" zone as it trades below the lowest PE boundary of 29.2 times ($701.78). This represents a significant valuation compression from earlier periods, with the stock currently trading at approximately 25.2 times earnings based on its position relative to the PE stream boundaries. The current price level suggests the stock has moved into attractive valuation territory after experiencing substantial multiple contraction. Analyzing the historical trend, ASML's valuation journey shows distinct phases of expansion and contraction. From 2020 to mid-2021, the stock experienced dramatic PE multiple expansion, moving from the "undervalued" zone (below 29.2x) to the "warning" zone (above 69.7x), with prices reaching over $819 in September 2021. The stock then underwent a significant valuation reset through 2022, falling back into more reasonable territory between the 29.2x and 37.3x PE boundaries. Throughout 2023 and early 2024, ASML traded primarily in the "fair value" to "watch" zones (between 37.3x and 53.5x), with occasional spikes into "overvalued" territory. The recent decline to current levels represents a return to fundamentally attractive valuations not seen since the early stages of the semiconductor boom, suggesting potential value opportunity for long-term investors as the stock trades at its most compelling PE multiple in several years.
