European equities rebounded on Sept. 30, with the pan-European STOXX 600 up 0.7% at 642.69 points by 0722 GMT, while remaining on track for its first monthly decline in six months. The index was expected to fall about 1.5% in September in the newer estimate, compared with an earlier estimate of nearly 2%, as elevated sovereign yields, energy costs, Middle East tensions and artificial-intelligence-sector concerns weighed on valuations. Technology and semiconductor-equipment shares gained after U.S. President Donald Trump backed voluntary AI safety standards and rapid data-center expansion, while mining stocks advanced and Glencore rose after Australia approved continued operations at its Hunter Valley thermal coal project through 2045. Investors awaited European inflation, employment and retail data, U.S. PCE inflation and comments from European Central Bank official Frank Elderson.
