SINGAPORE — Shares in Asia-Pacific were mixed in Wednesday morning trade following losses on Wall Street with the S&P 500 ending its seven-day winning streak.

Hong Kong’s Hang Seng index led losses among the region’s major markets, falling 0.9%. Chinese electric carmaker Xpeng made its debut in Hong Kong on Wednesday, with shares rising nearly 2% from their issue price in the early moments of trading.

In Japan, the Nikkei 225 dropped 0.75% while the Topix index declined 0.52%. South Korea’s Kospi shed 0.68%.
