Global markets outperform US stocks in 2025, marking the widest gap since 2009 as international gains surge

In Short:
– Global markets outperformed U.S. stocks in 2025, with international equities showing significant gains.
– Helen Jewell highlighted that international performance was key, aided by the U.S. dollar’s decline.

In 2025, U.S. investors watching AI stocks closely may have missed the bigger picture: international markets delivered their strongest performance against U.S. equities in over three decades. While the S&P 500 rose just 15%, foreign markets outperformed by more than 10 percentage points, led by South Korea, Peru, and other European nations.

Helen Jewell, BlackRock’s CIO, highlighted that the dollar’s 13% decline earlier in the year further amplified returns for Americans holding foreign assets. This marked the widest performance gap since 2009 and reminded investors of the value of diversification beyond domestic tech giants.

Continued Tech Rally

Nvidia, Tesla, and Palantir Technologies emerged as the most-viewed ticker pages on Yahoo Finance in 2025. Nvidia alone attracted 250 million page views, while Palantir soared an eye-popping 140% for the year. Despite this hype, the S&P 500 lagged behind global peers, showing that concentrated U.S. tech gains can mask broader market opportunities.

U.S. stocks saw a boost after Micron Technology exceeded earnings expectations, jumping 10% on strong AI-related demand. The Technology Select Sector SPDR Fund also gained 1.5%, driven by semiconductor optimism. However, analysts warn investors to avoid over-concentration in U.S. tech, even if AI-driven rallies persist into 2026.

As portfolios prepare for next year, the key question is whether semiconductor demand will expand beyond AI applications. Diversification remains essential, balancing excitement over tech gains with the risks of narrow market exposure.
