Tech stocks retreat, oil dips after Trump holds off on Iran attack

Asian markets wavered Tuesday, with tech stocks leading losses as investors tracked easing oil prices and cautious optimism over a potential US-Iran deal. South Korea’s Kospi slid by more than 3.0 percent, as tech stocks lost ground tracking an overnight slump on Wall Street. But it was the energy markets that drew attention after US President Donald Trump signalled “serious negotiations” with Tehran and called off planned strikes, boosting optimism that tensions could reduce.
