(Sharecast News) - Asia-Pacific markets exhibited mixed performance on Tuesday, with Chinese stocks leading the declines amidst a backdrop of political uncertainty in the US.

Despite that uncertainty, equities on Wall Street still managed to post gains overnight.

"Traders are taking advantage of the recent market slump to buy stocks at a discount, especially in the technology sector," said TickMill market analyst Patrick Munnelly.

"However, they are cautious about making big moves before the release of key US inflation data later in the week.

"The upcoming inflation data could have a significant impact on interest rate expectations, with the US Fed widely anticipated to lower rates by a quarter point in September."

Munnelly also noted the People's Bank of China's surprise reduction in its one-year benchmark loan prime rate in a bid to support its slowing economy.

"Asian currencies also strengthened against a weakening dollar.

"Following a significant tech selloff due to high valuations and sectoral rotation, markets are now pausing for breath.

"While the US election remains a major focus, Kamala Harris has secured enough pledged delegates to win the Democratic presidential nomination, bringing clarity to that aspect of the political landscape."
