Traditional diversification is eroding as AI infrastructure growth forces value ETFs and emerging market funds to adopt heavy tech weightings, leaving retirees exposed to unexpected volatility.
TSM anchors roughly 22% of major emerging market indexes, a weighting that doubled in 18 months due to AI capex.
NVDA is highlighted as a top stock and central to the AI trade embedded in portfolios.
CSCO is now running high-growth AI infrastructure businesses, moving from slow-growth dividend name.
Oracle's cloud infrastructure revenue grew 121% year over year, reflecting AI-driven growth outside traditional value profile.
Amazon is now the largest holding in the Russell Large value index at 6%, reflecting value index tech exposure.
Alibaba is increasingly held for its AI cloud and compute story rather than e-commerce.
Berkshire Hathaway fits the AI exposure pattern through its Apple stake and Alphabet position.
Alphabet is mentioned as part of Berkshire's AI-related holdings.
Apple is cited as looking like a value stock relative to AI hardware revenue growth.
Microsoft is cited as looking like a value stock relative to AI hardware revenue growth.
Morningstar strategist Tom Lauricella warns that traditional diversification strategies are failing as AI-driven growth infiltrates value and emerging market funds. With TSM now anchoring 22% of EM indexes and tech exposure in value ETFs doubling to over 25%, investors are unknowingly holding concentrated AI bets.
The extreme growth in AI hardware and infrastructure revenue has caused traditional value stocks to be eclipsed by tech-adjacent companies, forcing index weightings to shift toward firms like Oracle, Cisco, and Amazon.
