## MPWR PE Stream Chart Analysis **Current Valuation (Latest Data Point — mid-March 2026):** MPWR's most recent monthly average price stands at approximately **$1,075.29**, which places it firmly within the **"Value" Interval** — trading above the 14.2x PE boundary (priced at ~$181.57) and below the 34.3x PE boundary (priced at ~$439.82). Wait — re-examining the boundaries at the latest data point (2026-03-18): PE_stream_1 (14.2 times) = $181.57, PE_stream_2 (34.3 times) = $439.82, PE_stream_3 (54.4 times) = $697.93, PE_stream_4 (74.6 times) = $956.18, PE_stream_5 (94.7 times) = $1,214.43, and PE_stream_6 (114.8 times) = $1,472.68. With a current price of **$1,075.29**, MPWR is trading **between the 74.6 times boundary ($956.18) and the 94.7 times boundary ($1,214.43)**, placing it in the **"Overvalued" zone**. This suggests the stock is pricing in elevated earnings expectations, and investors should approach with caution as the valuation sits in the upper range of its historical PE band structure. **Historical Valuation Trend (Q1'21 through Q1'26):** From Q1'21 through most of 2022, MPWR's monthly average price hovered predominantly in the **"Fair" to "Watch" Interval** (between the 54.4 times and 74.6 times PE boundaries), with prices ranging roughly from $316 to $534. A notable compression occurred through 2022, as the stock pulled back from its late-2021 highs near $534 and briefly dipped toward the lower PE bands, reflecting broader market de-rating pressures. From Q1'23 onward, the stock began a sustained recovery and valuation re-expansion — prices climbed from the mid-$300s back through the "Fair" zone and into the "Watch" Interval by mid-2023. The most dramatic valuation shift occurred from late 2023 through Q3'24, when MPWR surged from approximately $594 to a peak near **$897 in late 2024**, pushing the stock into the **"Overvalued" zone** (between 74.6 times and 94.7 times). A sharp correction followed in Q4'24, with prices dropping to the mid-$500s to low-$600s — briefly retreating toward the "Watch" Interval — before recovering strongly through 2025 and into early 2026. The PE stream boundaries themselves underwent a significant structural reset around Q4'24–Q1'25, reflecting an earnings revision, which dramatically repositioned the band levels. Overall, the trend of the PE river chart has been **broadly upward**, indicating growing earnings power, though the stock's current positioning in the "Overvalued" zone warrants careful monitoring before initiating new positions.
