## ASML PE Stream Chart Analysis As of the latest data point (mid-March 2026), ASML's monthly average price stands at approximately **$1,355.17**, placing it firmly in the **"Watch" (觀望)** zone — between the 45.0x PE boundary (priced at ~$1,108.33) and the 53.0x PE boundary (priced at ~$1,305.37). More precisely, the current price has actually breached the 53.0x boundary and is approaching the **"Overvalued" (高估)** threshold of 61.0x (priced at ~$1,502.65), suggesting the stock is trading at a relatively elevated valuation. With the price sitting between the 53.0x and 61.0x PE bands, investors should note that the stock is not yet in the "Warning" (警示) zone (≥69.0x, ~$1,699.69), but the upward momentum from late 2025 into early 2026 warrants close attention. Looking at the historical trend from early 2021 through early 2026, ASML's valuation journey has been notably dynamic. In early 2021, the stock traded around $506–$547, comfortably within the **"Fair" (合理)** to **"Watch"** zone relative to the then-prevailing PE bands. Through mid-2021 to late 2021, prices climbed toward $800–$811, pushing into the **"Overvalued"** territory as the stock approached and briefly tested the 53.0x–61.0x interval. A meaningful correction followed through 2022, with prices retreating to the $427–$617 range — pulling the stock back down toward the **"Value" (價值)** and **"Fair"** zones, reflecting a period of valuation contraction. The recovery through 2023 was gradual, with prices recovering to the $580–$716 range, largely oscillating in the **"Fair"** to **"Watch"** interval. A significant re-rating occurred in early-to-mid 2024, when prices surged to the $900–$1,014 range, briefly entering **"Overvalued"** territory near the 53.0x boundary. However, a sharp pullback in late 2024 brought prices back to the $664–$752 range, compressing valuations back toward the **"Fair"** zone. The most striking development is the powerful rally from late 2025 into early 2026, with prices surging from ~$863 in September 2025 to over $1,434 by February 2026 — a move that has driven the stock from the **"Fair"** zone all the way through **"Watch"** and into **"Overvalued"** territory. The PE stream boundaries themselves have also been trending upward over this period, reflecting improving earnings expectations, yet the price appreciation has outpaced earnings growth in recent months, signaling elevated but not yet extreme valuation risk.
