Are stocks overvalued in 2026? Is the stock market repeating the dot-com bubble of 1999, or could artificial intelligence (AI) and stronger economic growth justify today's historically high valuations?
In this episode of "Through the Noise", financial economist Cam Harvey joins Robert Olinger to examine stock market valuations, the Shiller CAPE ratio, price-to-earnings (P/E) ratios, and whether investors should be concerned about a potential market correction.
The Shiller Cyclically Adjusted Price-to-Earnings (CAPE) ratio has climbed above 40, compared with a historical average below 18. The only other period when valuations reached similar levels was during the dot-com bubble in 1999. But does that comparison tell the whole story?
Cam Harvey challenges conventional interpretations of market valuation metrics, explaining why changes in industry composition, the growing importance of technology companies, and the accelerating impact of AI make historical comparisons potentially misleading.
Using examples from Alphabet, Amazon, and NVIDIA, Harvey explains how expected earnings growth influences stock prices and why backward-looking valuation measures may fail to capture the economy's future growth opportunities.
Harvey also presents a contrarian perspective: investors may be underestimating the potential for AI-driven productivity gains and economic expansion. While some stocks could be overvalued and vulnerable to corrections, broader market valuations may have more room to rise than traditional indicators suggest.

Is Wall Street overvalued, or is the market failing to recognize a new era of economic growth?
