Japan's September core CPI YoY due in 10 minutes.

US stocks opened lower: Dow down 0.13%, S&P 500 down 0.88%, Nasdaq down 1.5%. Major tech and chip names led losses—SanDisk (SNDK.O) -4.8%, SK Hynix (SKHY.O) -4.5%, Meta Platforms (META.O) -4.0%, SpaceX (SPCX.O) -4.0%, Micron Technology (MU.O) -3.8%, Tesla (TSLA.O) -2.87%, IBM (IBM.N) -2.5%, NVIDIA (NVDA.O) -2.1%.

South Korea's KOSPI fell 201.89 points, or 3.52%, to 5,533.77 on Thursday, its lowest close since April 7, as chipmakers led losses amid profit-taking and renewed skepticism over the global AI investment boom. The drop followed a 3.3% rally on Wednesday, the index's biggest one-day gain in six weeks. A hawkish Bank of Korea stance also reinforced expectations of further rate hikes. Earnings from Meta and Tesla failed to deliver the same market lift as results linked to SpaceX and SMCI, leaving chip stocks vulnerable to a pullback.
