“H1 2026 was dominated by technology, especially artificial intelligence-related semiconductor stocks,” said Mathieu Racheter, head of equity strategy research at Julius Baer.

“Since July, however, market leadership has broadened beyond technology towards sectors such as financials and healthcare.

“We expect this trend to continue. Importantly, this is not a negative call on AI; semiconductor fundamentals remain strong and hyperscalers continue to raise their capex guidance.”
