Market Matters – AI takes a breather

Markets suffered a concentrated AI-led correction rather than a broad risk-off move. The S&P 500 fell 2.55% over the week, with the most acute weakness in AI-linked and semiconductor-heavy areas following Broadcom’s results. Regional markets appeared more resilient, but Asia and Europe had not fully reflected Friday’s late US sell-off, making the next open an important test.

The AI investment case remains intact, but valuation discipline is returning. Broadcom did not undermine the structural AI infrastructure thesis; rather, it failed to meet a market priced for NVIDIA-style upside. The key issue is not whether AI demand is real, but whether some share prices had discounted too much good news too quickly.

Strong US labour data reduced hopes of near-term Fed support. Non-farm payrolls rose by 172,000 in May, well ahead of expectations, with prior months revised higher and unemployment steady at 4.3%. This pushed yields higher and reinforced the risk that resilient growth, elevated oil and sticky inflation keep policy tighter for longer.

Geopolitical risk remains a live inflation threat. The Middle East ceasefire remains fragile after fresh US-Iran exchanges and continued regional attacks. Brent near $93 and WTI above $90 suggest markets have moved from acute Hormuz panic to a more persistent duration-risk premium, with implications for fuel, transport, food and producer costs.

The base case remains constructive, but the short-term narrative is being tested. This looks more like a valuation reset than a bubble bursting. A period of consolidation could be healthy if leadership broadens beyond crowded semiconductor names, but if weakness spreads into credit, defensives and broader earnings expectations, the signal will become more concerning.
