1413 GMT - With stock-market valuations sky-high as investors make big bets on artificial-intelligence technology, a market correction looks probable, European Central Bank economists say in a blogpost. The rally in the tech sector has brought valuations to levels last seen during the dot-com bubble, they say. "Economic research on past technological revolutions points to a worrisome conclusion: a correction of current stock-market valuations is likely." Unlike during the dot-com bubble, there is less room this time to cut interest rates or use fiscal policy to cushion the fallout, they say. A correction would have severe consequences for the eurozone through investors' direct exposure to the U.S.'s Magnificent Seven tech stocks, and the "overexuberance" in European stock markets themselves, the economists add.
