## ONTO PE Stream Chart Analysis **Current Valuation (Latest Data Point — mid-March 2026):** ONTO's latest monthly average price stands at approximately $201.88, while the PE stream boundaries at this date are: 15.8x at $43.88, 32.2x at $89.54, 48.5x at $135.18, 65.0x at $180.84, 81.3x at $226.47, and 97.7x at $272.14. The current price of $201.88 falls between the 65.0x boundary ($180.84) and the 81.3x boundary ($226.47), placing ONTO firmly in the **"Overvalued"** zone. This indicates the market is pricing the stock at a relatively elevated PE multiple compared to its historical range, suggesting investors should exercise caution and monitor closely before initiating or adding to positions. **Historical Valuation Trend:** From early 2021 through mid-2022, ONTO's stock price remained well below the 32.2x boundary, residing in the **"Undervalued"** to **"Value"** interval — a period of attractive entry points. As earnings streams expanded through late 2022 and into 2023, the price gradually climbed into the **"Fair"** (32.2x–48.5x) interval. A significant re-rating occurred from mid-2023 through mid-2024, when the stock surged from roughly $110 to a peak near $219, briefly touching the upper edge of the **"Fair"** zone and approaching the **"Watch"** (48.5x–65.0x) interval. Notably, the PE stream boundaries themselves shifted downward during late 2023 and early 2024 — reflecting a contraction in underlying earnings estimates — which paradoxically pushed the stock's relative PE positioning higher even as absolute prices rose. Following a sharp correction from mid-2024 through mid-2025 (price falling from ~$219 to ~$97), the stock briefly retreated into the **"Fair"** interval, offering a more reasonable valuation. However, a strong recovery through late 2025 and into early 2026 has pushed the price back into the **"Overvalued"** zone. The overall PE stream trend shows a downward-then-stabilizing trajectory in the boundary lines, indicating earnings growth has been uneven, which warrants careful attention to the sustainability of the current elevated valuation.
