π After European Banks Outperform, What Will Continue to Drive AI Valuations Higher
European bank stocks have outperformed the βMag-7β since 2022, demonstrating at least one fact: the market in recent years has not offered only one path to higher returns through large AI technology companies. For capital allocation, this weakens the premise that investors must concentrate their holdings in AI leaders, and makes whether traditional financial sectors are undervalued a question that needs comparison.
The more critical constraint comes from valuation. Gina Martin Adams noted that the Shiller cyclically adjusted price-to-earnings ratio (CAPE) is approaching the highs of the internet bubble, while the cumulative increase in stock prices has lagged earnings growth. If this observation holds, subsequent index returns will find it harder to rely primarily on further expansion in valuation multiples. When investors buy high-valuation AI leaders, they need to see continued delivery of profit growth rather than merely expect the market to be willing to pay higher prices.
This does not mean the AI trade will reverse immediately. European banksβ relative outperformance also cannot by itself prove that the AI bubble has already burst. But it suggests that the risk of crowded trades comes not only from earnings falling short of expectations, but also from other sectors offering more competitive returns. When room for valuation expansion narrows, differences in earnings delivery across industries will more directly affect capital flows.
