Asia-Pacific markets are set to open lower on Thursday, tracking losses on Wall Street as investors assess results from tech giant Nvidia. Nvidia reported second-quarter earnings that beat Wall Street expectations and provided stronger-than-expected guidance for the current quarter. The company also authorized an additional share buyback of $50 billion. Revenue for the second quarter came in at $30 billion, up 15% from the previous quarter and 122% higher from a year ago. However, the firm's shares fell 8% in extended trading. Investors in Asia will watch for any spillover to tech stocks in the region, which is home to companies along Nvidia's value chain like Taiwan Semiconductor Manufacturing Company and SK Hynix. Japan's Nikkei 225 futures pointed to a weaker open for the market, with the futures contract in Chicago at 37,960 and its counterpart in Osaka at 38,150 compared to the previous close of 38,371.76. Futures for Australia's S&P/ASX 200 stood at 8,004, slightly lower than its last close of 8,071.4. Hong Kong Hang Seng index futures were at 17,648, lower than the HSI's last close of 17,692.45.
