SOX · Consensus Forward PE — Philadelphia Semiconductor forward PE — read from 2011

Forward PE — The SOX forward-PE corridor and where the AI cycle sits in it.

Terminal data carries the SOX forward P/E back to January 2002, published weekly. Through 2002–2010 aggregate semiconductor earnings repeatedly approached and crossed zero: where no P/E exists the source returns a blank and the line is left broken rather than bridged; where one exists but sits at the pole it runs far above the chart's ceiling, peaking above 190× in June 2009; the note under the chart counts those readings off the published series. Those are division by an earnings base rounding to zero, not multiples anyone paid, so the mean and percentile are computed from 2011 onward. Across that clean modern cycle semis trade in a roughly 9–30× corridor, its top set in June 2024 by the AI cycle. Today's reading and where it sits in that modern era are on the metric strip below the chart.
