TOKYO (Reuters) - Asian stocks gained on Thursday, tracking Wall Street's tech-led rally overnight after an as-expected reading of U.S. consumer inflation cemented bets for a Federal Reserve interest-rate cut next week.
Japan's Nikkei topped 40,000 for the first time since mid-October, led by advances in chip-sector shares. The exporter-heavy index also got a boost from a weakening yen, as traders pared bets for a Bank of Japan rate hike next week.
The Australian dollar surged after employment data topped estimates by a wide margin, rebounding from Wednesday's weakness following a Reuters report that Beijing is considering allowing the yuan to depreciate further next year. China is Australia's top trading partner and the Aussie is often used as a liquid proxy for the yuan.

Overnight, the tech-focused Nasdaq shot up 1.8% to close above 20,000 for the first time, while the S&P 500 climbed 0.8%. Futures for both indexes, however, pointed to 0.2% declines.
The U.S. consumer price index rose 0.3% last month, the largest gain since April, but exactly as forecast by economists in a Reuters poll and not hot enough to derail Fed officials from normalizing policy, analysts said.
"The U.S. CPI print lit a flame in U.S. equity," said Chris Weston, head of research at Pepperstone.
"The market has essentially seen one of the last remaining obstacles that could derail sentiment out of the way", he said, "seeing the coast somewhat clearer for the illustrious seasonal chase of returns to play out into year-end."
