Summary

The S&P 500's Shiller CAPE ratio hit 41, a level only exceeded during the dot-com bubble. Meanwhile, the PEG ratio is at its lowest in at least three decades, possibly its cheapest ever. The two valuation methods send conflicting signals, hinging on the difference between expected and historical growth.

Bubble analysis

The CAPE ratio near its all-time high while the PEG ratio suggests cheapness reflects market pricing of high growth expectations, largely driven by AI. If growth disappoints, valuations could be unsustainable, signaling bubble risk.
