A coordinated shift away from US-centric equity portfolios is urgently required to protect global investors from a severe valuation correction, according to Ian Goldin, a former World Bank official and Oxford University professor.

Goldin argues that the current extreme concentration of capital in a handful of US technology giants creates a fragile market structure that could result in significant losses for savers worldwide if a reversal occurs.

A prominent asset manager recently cautioned that global markets face a potential 10% correction, pointing to extreme levels of investor optimism captured in the latest Bank of America sentiment survey.

The warning arrives as concerns over US equity valuations intensify.

Goldin’s comments reinforce the view that the breadth of the current rally is dangerously narrow, with disproportionate weight resting on a small segment of the US market.

This perspective aligns with broader institutional warnings about global economic risks.
