China's stock markets surged on Tuesday thanks to pent-up demand from a weeklong trading break — but jittery investors kept a lid on the rally.
The country's benchmark CSI 300 Index opened nearly 11% higher but the gains pared swiftly. The index closed 5.9% higher.
Benchmark indexes on the Shanghai and Shenzhen markets also ended sharply higher after intraday gyrations.
Sentiment in China's stock markets — which entered 2024 in meltdown mode — has been massively bolstered by Beijing's September 24 announcement of aggressive stimulus to support its flagging economy. The CSI 300 is about 25% higher year to date.
China, the world's second-largest economy, is dealing with multiple challenges, including a property crisis, deflation, and high youth unemployment.
Even before Tuesday's opening, China's social media was abuzz with what the stock markets may hold following the weeklong National Day break.
On Tuesday, hashtags about China's stock market — including the apt #A-shares rollercoaster — rushed to the top of Weibo's trending list. A-shares are stocks of Chinese companies listed on the Shanghai and Shenzhen stock exchanges.
Chinese shares came off their highs on Tuesday in part because investors were disappointed by announcements at a press briefing by China's top economic planner, the National Development and Reform Commission.
The commission did not announce fresh fiscal stimulus, which fell short of market expectations, Yue Su, the principal China economist at the Economist Intelligence Unit, wrote Tuesday.
Still, the commission's messaging was positive, Su said: "We believe the pro-growth policy stance remains unchanged."
However, the stock-market euphoria before the weeklong break might have prompted the Chinese government to be more cautious in its stimulus measures to ensure that resources flow into weaker areas of the economy, she added.
Tuesday's stock volatility showed that China's economic fundamentals haven't caught up with market expectations, Hao Zhou, the chief economist of Guotai Junan International, told CNBC.
"The market was expecting too much from the government," he said on Tuesday.
In Hong Kong, the Hang Seng Index closed nearly 10% lower.
The index is still about 25% higher year to date following strong gains during the weeklong break.
