Most Asian stocks fell on Thursday as fears of a U.S. debt default persisted amid little progress toward raising the debt ceiling, although chipmaking stocks outperformed tracking a robust outlook from Nvidia. Japan’s Nikkei 225 index rose 0.6%, supported chiefly by nearly 16% jump in semiconductor testing equipment maker Advantest Corp (TYO:6857). The stock, which ranks Nvidia among its clients, was trading at a record high of 16,280 yen. Gains in other chipmaking stocks, such as wafer maker SUMCO Corp (TYO:3436) and Tokyo Electron Ltd (TYO:8035), helped the Nikkei move back towards 33-year highs after some losses this week. Nvidia Corporation (NASDAQ:NVDA) rallied in overnight trade after the graphics cards maker beat expectations with its first-quarter earnings and forecast stronger revenue on robust demand from artificial intelligence development. The positive outlook from Nvidia brightened the outlook for the chipmaking sector, which is otherwise grappling with a potential demand slowdown in the face of worsening global economic conditions. This benefited other chipmaking stocks, with South Korea’s Samsung Electronics Co Ltd (KS:005930) up 1%. Taiwan Semiconductor Manufacturing Co (TW:2330), which is also a major Nvidia supplier, jumped nearly 3%, helping the Taiwan Weighted index rise 0.6%. But broader Asian markets retreated, tracking a weak lead-in from Wall Street as U.S. lawmakers flagged slow progress in negotiations over raising the debt ceiling. Sentiment was also rattled by ratings agency Fitch flagging a potential U.S. credit downgrade in the event of a default.
