Fabien Yip, a market analyst, stated, "The sharp declines have been triggered by the large correction in U.S. tech last Friday following the blowout numbers on non-farm payrolls." Yip added, "There was a spillover from the fading optimism on the AI trade, particularly affecting picks-and-shovels tech companies in Asia, which enjoyed a spectacular run in the past two months." He also said, "Further, the weak won and potential tightening from South Korea could potentially add strain for the leveraged positions in Korea."
