According to Mathieu Racheter, head of equity strategy research at Julius Baer, the first half of 2026 was characterized by technology, particularly artificial intelligence-related semiconductor stocks.
However, since July, the market's leadership has expanded beyond technology to encompass sectors like financials and healthcare. Racheter anticipates this trend to persist, emphasizing that this is not a negative outlook on AI; rather, semiconductor fundamentals remain robust, and hyperscalers continue to raise their capex guidance.
