Most Asian stock markets declined on Thursday as investor concerns over artificial intelligence (AI) spending continued to pressure technology shares, overshadowing strong earnings from Samsung Electronics and upbeat results from major U.S. tech companies. Market sentiment also remained cautious after the U.S. Federal Reserve left interest rates unchanged and offered few clues on the timing of its next policy move. U.S. stock index futures edged higher in early Asian trading after Microsoft delivered stronger-than-expected quarterly earnings, helping recover part of the previous session’s losses. South Korea’s KOSPI index was among the most volatile markets, ending about 0.5% lower after swinging sharply between gains and losses. Investors also assessed earnings from Microsoft and Meta Platforms.
