## AMAT PE Stream Chart Analysis **Current Valuation (Latest Data Point):** As of the most recent data point (mid-March 2026), AMAT's price stands at approximately **$349.47**, which places it precisely at the upper boundary of the **35.6x PE** band (PE_stream_6 score: ~$349.48). This positions the stock squarely in the **"Warning" zone** — the highest valuation tier — indicating that the stock is trading at a historically elevated multiple relative to its earnings. With the 30.6x boundary (PE_stream_5) at ~$300.61 and the 35.6x ceiling at ~$349.48, the current price is essentially testing the very top of the defined PE range, suggesting significant valuation stretch and limited margin of safety for new investors. **Historical Valuation Trend:** Over the observed period beginning in early 2021, AMAT's valuation journey has been dynamic and instructive. In early 2021, the stock traded around $95–$113, comfortably within the **"Fair" to "Watch" interval** (between the 15.7x and 20.7x bands, which were priced at roughly $66–$87 at the time), reflecting a moderately valued growth stock. Through mid-2021 into early 2022, prices climbed toward the $130–$147 range, pushing into the **"Overvalued" to "Warning" interval** as the stock approached and occasionally exceeded the 20.7x boundary (~$120–$150). The bear market of 2022 brought a sharp correction, with prices falling to the $80–$100 range — briefly touching the **"Undervalued" zone** near the 10.7x boundary (~$80), representing one of the most attractive entry points in the entire observed history. The recovery through 2023 was gradual, with prices re-entering the **"Fair" interval** (between 15.7x and 20.7x bands) for much of the year. The pivotal re-rating began in early 2024, when prices surged from ~$156 to over $227 by mid-2024, breaking decisively into the **"Warning" zone** above the 25.6x band. Although a pullback in late 2024 and early-to-mid 2025 temporarily brought the stock back into the **"Overvalued" interval** (between 20.7x and 25.6x), the powerful rally from late 2025 through early 2026 — with prices climbing from ~$223 to $349 — has driven AMAT back to its most elevated valuation level in the entire dataset. The PE stream lines themselves have trended modestly upward throughout the period, reflecting gradual earnings growth, but the pace of price appreciation has far outstripped earnings expansion, resulting in clear and sustained valuation expansion into "Warning" territory.
