Alibaba outperforms among Chinese tech

In Hong Kong, Chinese e-commerce giant Alibaba rose 0.43% on Tuesday, adding to gains of more than 6% on Monday. The Chinese central bank announced Monday that Alibaba's financial technology affiliate Ant Group is to restructure as a financial holding company.

Hong Kong-listed shares of chipmaker SMIC also jumped 1.19%.

Other Hong Kong-listed Chinese tech firms declined. Tencent slipped 0.9% while Meituan plunged 7.44%. The broader Hang Seng TECH index fell 1.6% to 8,038.81.

Tech titans Tencent and Meituan were among 34 firms mentioned in a statement released Tuesday by Chinese regulators that warned so-called "platform companies" to make sure they examine their actions and rectify any anti-competitive practices within a month. It comes just days after Alibaba was slapped with a $2.8 billion fine for violating anti-monopoly rules.

China's March exports miss expectations

China's exports in March rose 30.6% from a year ago, according to customs data released Tuesday. Economists had expected exports to grow 35.5% from a year ago, according to a Reuters poll.

Chinese imports for March jumped 38.1% from a year earlier, above expectations in a Reuters poll for a 23.3% on-year increase.

Overnight stateside, the S&P 500 ended its trading day little changed at 4,127.99 while the Dow Jones Industrial Average shed 55.2 points to close at 33,745.40. The Nasdaq Composite slipped 0.36% on the day to 13,850.

The muted moves on Wall Street came as investors waited for the release of inflation numbers due out on Tuesday stateside.
