what happened
Asian equities opened lower on Tuesday, October 20, following a softer tone in the region, according to Moody's. The move came after Wall Street closed higher overnight: the Nasdaq gained 1.11% and the S&P 500 added 0.41%. South Korea's Kospi opened down 3.5%, with chip shares under pressure; SK Hynix lost 4.07% and Samsung Electronics slipped 1.03%. The index's year-to-date advance has shrunk to roughly 31%, far below the near-116% gain it had posted at its June peak.
Japan's Nikkei 225 fell 1.21% in morning trade, with SoftBank Group down 4.46%. Australia's ASX 200 dropped 0.84%, while Taiwan's Taiex edged up 0.30% after an early dip. India's GIFT Nifty was flat to slightly lower, and the domestic market stays shut for Dussehra.
why it matters
Weakness in technology, especially semiconductors, is weighing on Asian indices. On Monday in the US, Nvidia and AMD rebounded after last week's sell-off linked to concerns over financing artificial intelligence investments. Investors now turn to a busy earnings week that includes Tesla and Meta Platforms.
