Europe’s Stock Market Boom Is Hiding a Darker Truth

European stock markets are booming. But that doesn’t mean Europe is. Traditionally, a bet on European equities is actually a bet on growth everywhere else. The companies that make up the Stoxx Europe 600 — which has risen by about 12% this year — get almost half their revenues outside the continent, according to the index’s owners. America’s S&P 500 brings in less than 30% from elsewhere.

This is partly good news. The European Union is home to world-beating companies in luxury, pharmaceuticals and engineering that produce goods prized everywhere. The downside is that the state of Europe’s stock market has never been a great proxy for the health of its economy, and especially as a gauge of local demand for goods and services.

The US stock market is dominated right now by a handful of tech companies, while Europe has “heavy asset, low obsolescence” old-economy stalwarts. Thus moments of excitement or depression about artificial intelligence make one or the other look temporarily more attractive.

But that very dynamic shows the difference between the US and Europe goes far deeper than the sectoral composition of its markets. Typically, investors’ choices about European equities are determined by what’s going on elsewhere, rather than because something has changed in the continent itself. For example, engineering companies that provide basic kit for data centers, such as France’s Schneider Electric SE, are prospering from AI mania. But demand for this stuff is driven by the US and Asia.

In past decades, the success of corporate Europe globally has disguised the bloc’s slide toward domestic stagnation. Business leaders and their shareholders have been happy enough, allowing the continent’s politicians to duck the hard choices in election after election on how to jack up local demand. The bloc’s growth rate, close to 1% over the past year, is a truer guide than the Stoxx Europe 600.

Sure, pressure to reform appears to be gaining steam, but this is being framed in terms of sovereignty and industrial competitiveness, not just simple national prosperity as would be the case in America. And this newfound zeal for change has materialized only because threats from China and Russia — economic and military — have become impossible to ignore. Europe’s leaders still haven’t answered the central question: What, exactly, will propel their economies? So far, the default answer has been: “Growth everywhere else.” But what if that stops working?
