Expert Analysis Signals Potential Risks
According to John Higgins, Chief Economic Adviser at Capital Economics, a recent surge in foreign investment purchasing U.S. stocks may serve as an indicator of potential troubles facing the S&P 500 index. Mr. Higgins noted that historical instances of similar buying surges have been followed by significant market downturns, citing the bursting of the dotcom bubble, the global financial crisis (GFC), and the market decline observed in 2022.
Shifting Investment Patterns and Historical Trends
While foreign investors naturally tend to accumulate U.S. financial assets due to the nation’s consistent current account deficit—which recorded net liabilities exceeding $21 trillion at the close of the first quarter—Capital Economics pointed out that the composition of these holdings has undergone a major transformation.
The firm highlighted a significant shift in asset preference: two decades ago, foreign portfolio investments were primarily concentrated in debt securities. Today, however, they are predominantly invested in equities. John Higgins observed that foreign ownership stakes in U.S. stocks have grown dramatically to exceed 21%, representing a substantial increase from the just over 6% recorded in 1997.
Historical Correlation and Forward Outlook
Capital Economics stated that historical evidence indicates a pattern where “substantial increases in foreigners’ net purchases of US equities have coincided with sizeable rallies in the S&P 500 that have subsequently reversed.” The firm cited the dotcom bubble, the GFC, and the 2022 pullback as examples supporting this claim.
Furthermore, Capital Economics observed that the current volume of foreign buying, accompanying the recent stock market gains, has been “much larger than the increases in foreigners’ net purchases of US equities during the rallies of those earlier episodes.”
The analysis cautioned that the ongoing trend of buying, which is driven by Artificial Intelligence (AI), could potentially reverse if and when the AI-related bubble bursts. Such a reversal might lead to U.S. equities performing worse compared to global market counterparts.
Regarding potential currency impacts, Capital Economics suggested that the future performance of the dollar in such an environment would heavily depend on the extent—if any—to which the Federal Reserve eased its monetary policy relative to other central banks.
