SINGAPORE — Shares in Asia-Pacific were mixed on Tuesday as investors watched for market reaction to U.S. President Joe Biden picking Jerome Powell for a second term as Federal Reserve chair.

Hong Kong’s Hang Seng index declined more than 1% as of its final hour of trading. Mainland Chinese stocks closed mixed, with the Shanghai composite up 0.2% to 3,589.09 while the Shenzhen component slipped 0.371% to 14,905.13.

South Korea’s Kospi dipped 0.53% to close at 2,997.33, with shares of biopharmaceutical firm Celltrion plunging 6%.

The S&P/ASX 200 in Australia closed 0.78% higher at 7,410.60.

MSCI’s broadest index of Asia-Pacific shares outside Japan declined 0.53%.

Markets in Japan were closed on Tuesday for a holiday.

Technology stocks in Asia fell on Tuesday, tracking losses seen by their peers overnight stateside.

Hong Kong-listed shares of Chinese tech giant Tencent fell 2.22% while Alibaba slipped 2.55% and Meituan plunged 2.48%. The Hang Seng Tech index declined by about 1.3%.

Those moves came as investors on Wall Street reacted to Biden picking Powell for another term as Fed chair. Biden had been under pressure to name a more progressive Democrat, rather than keep Republican Powell in the role.

Powell has guided the U.S. central bank and the country’s economy through the pandemic recession, unleashing unprecedented monetary stimulus to keep financial markets afloat. His renomination now heads to the Senate for confirmation.
