Asia-Pacific markets opened mixed Tuesday, tracking mixed gains on Wall Street as investors look toward the U.S. Federal Reserve's decision stateside.

Australia's S&P/ASX 200 traded 0.44% higher.

Japan's Nikkei 225 and Topix rose 0.34% and 0.29% respectively. South Korea's Kospi slipped 0.28% in its first hour of trade, while the Kosdaq dropped 0.2%.

Hong Kong's Hang Seng index futures were at 19,755, lower than the HSI's last close of 19,795.49.

Overnight in the U.S., the Nasdaq Composite advanced to a record, lifted by a rally in tech. The tech-heavy index gained 1.24% to 20,173.89, while the S&P 500 added 0.38%, closing at 6,074.08. The Dow Jones Industrial Average underperformed, losing 110.58 points, or 0.25%, to end at 43,717.48. The 30-stock Dow fell for an eighth day, marking its longest run of losses since 2018.

The Fed decision on Dec. 18 stateside will also be top of mind for investors, with the CME Fedwatch tool currently forecasting a 98.2% chance of a 25-basis-points cut.

Contrary to the general upward trend, market darling Nvidia, the artificial intelligence chipmaker that had driven stock gains over the past two years, saw a 1.7% decline. This drop pushed the stock into correction territory, falling over 10% from its recent all-time high in November.
