China’s AI stocks surge 65% in first half but bubble fears begin to weigh on sentiment
China’s AI stocks entered the second half of 2026 with improving earnings momentum, but scepticism about the sector is increasing

“It is only a matter of time now,” said Michael Burry, the US hedge fund manager, in a post on Substack on Tuesday. Burry, who famously shorted the American housing market before the 2008 financial crisis and whose story was later popularised in the 2015 film The Big Short, warned of what he sees as stretched valuations in AI-related markets.
Meanwhile, China’s technology sector showed a strong rally in the first half of the year. The SSE Star 50 index surged roughly 65 per cent during the January-to-June period, marking one of its strongest half-year performances on record, driven by gains in semiconductors, optical modules and AI infrastructure names.
