## PFE PE Stream Chart Analysis **Current Valuation (Latest Data Point):** As of the most recent data point (mid-March 2026), PFE's monthly average price stands at approximately **$27.32**, while the lowest PE boundary ( 6.0 times) is priced at **$8.22** and the second boundary (17.9 times) sits at **$24.55**. Since the current price of $27.32 exceeds the 17.9 times boundary ($24.55) but remains well below the 29.9 times boundary ($40.87), the stock is trading in the **"Fair Value"** zone — between the 17.9 times and 29.9 times PE interval. This suggests the stock is neither deeply discounted nor significantly overvalued relative to its historical earnings-based valuation bands, reflecting a moderate and reasonable pricing level for investors. **Historical Valuation Trend:** From early 2021 through late 2022, PFE's stock price hovered consistently in the **"Undervalued"** to **"Value"** zone relative to its PE bands, with monthly average prices ranging from roughly $27 to $45 — well below even the lowest PE stream boundaries, which were elevated due to strong earnings during the COVID vaccine cycle. The PE stream boundaries expanded dramatically through 2021 and into 2022, reflecting surging earnings, yet the stock price never came close to the higher PE bands (29.9 times and above), indicating the market was pricing PFE conservatively even at its peak. Beginning in early 2023, the PE stream boundaries began contracting sharply — a clear signal of declining earnings — and by late 2023 and early 2024, the boundaries collapsed to historically low levels (e.g., the 6.0 times boundary dropped to approximately $2.26–$4.52). During this period, PFE's price of roughly $24–$28 actually **exceeded** the highest PE boundary (65.7 times), placing the stock in the **"Warning"** zone — a paradoxical situation driven by severely compressed earnings rather than an overheated stock price. As earnings began recovering through 2024 and into 2025–2026, the PE stream boundaries gradually expanded again, and PFE's price has settled back into the **"Fair Value"** interval between 17.9 times and 29.9 times. The overall PE river trend remains volatile and irregular, reflecting PFE's highly unstable earnings profile — characteristic of a company navigating a post-pandemic earnings normalization cycle — which limits the reliability of PE stream analysis as a standalone valuation tool for this stock.
