Il Nuovo Postiglione - Stocks torn between Fed rate warning, AI optimism

Chinese tech firms stood out, with Alibaba shares rocketing after its chief executive said the e-commerce giant planned to ramp up spending on artificial intelligence.

Investors have enjoyed a months-long rally for equities that has pushed some markets to record highs, but the run-up took a pause Tuesday amid talk that the gains may have gone too far.

Another key driver has been expectations that the Fed will continue to cut US interest rates before the end of the year.

However, Powell cooled expectations with a warning Tuesday that cutting rates too aggressively risked stoking inflation.

Powell's comments lent support to the dollar, which had come under pressure from rate-cut expectations.

Investors are awaiting the release on Friday of the personal consumption expenditure (PCE) index, the Fed's favoured gauge of US inflation, and key American jobs figures next week.

On Wednesday, the Hong Kong and Shanghai stock markets rallied thanks to a surge of more than nine percent in Alibaba -- which runs some of China's biggest online shopping platforms -- after CEO Eddie Wu unveiled plans to ramp up AI spending by about $53 billion.

"The industry's development speed far exceeded what we expected, and the industry's demand for AI infrastructure also far exceeded our anticipation," Wu told an audience at the firm's annual developer conference in Hangzhou, China.

Crude prices firmed Wednesday "after (US President) Donald Trump ramped up further pressure on sanctions on Russian oil", noted Kathleen Brooks, research director at XTB.
