European equities advanced on Wednesday, with the STOXX 600 gaining 0.7% after two sessions of limited movement. Germany’s DAX and London’s FTSE 100 each rose 0.7%, while the STOXX 50 added 0.5% to reach its highest level in three weeks. Technology and semiconductor-equipment stocks led the advance after President Donald Trump backed voluntary artificial-intelligence safety frameworks and reiterated support for faster data-center construction. Alphabet shares rose 3% after the signing of a voluntary AI safety accord at the White House, which included Google CEO Sundar Pichai among its signatories. Apple gained 2.5%, while Meta Platforms slipped 0.3%. The comments eased concerns that regulation or recent AI model-training suspensions at OpenAI could prompt companies to reduce technology spending. ASML rose 0.8%, while Novartis, Airbus and Safran gained 1.1%, 1.3% and 1.2%, respectively. TotalEnergies fell 1% as the energy sector ended lower. Investors are awaiting German retail sales and labor-market data, French inflation, September German inflation and the U.S. August Personal Consumption Expenditures price index, the Federal Reserve’s preferred inflation gauge. Analysts expect U.S. inflation to remain unchanged from the previous month, a result that could support current interest-rate expectations as Treasury yields hover near multi-decade highs. ECB official Frank Elderson is also scheduled to speak later Wednesday. Despite the daily gain, the STOXX 600 is heading toward an approximately 2% September decline, its first monthly loss in six months. Rising government bond yields, higher energy costs and continued AI-sector volatility have weighed on European shares. Energy prices have risen again, partly because negotiations between the United States and Iran have stalled. In the third quarter, the STOXX 50 was essentially flat while the STOXX 600 declined 0.6%.
