China stocks edge up as weak GDP spurs stimulus hopes, Hong Kong shares slide

China stocks edged up on Monday as investors bet on more stimulus after the economy slowed more than expected in the second quarter amid a protracted property downturn and worries about jobs.

Hong Kong shares fell, however, following the weaker-than-expected data, as well as concerns of a higher probability of Donald Trump winning US elections after a surprising attack.

Some market participants placed high hopes on a key leadership gathering this week that starts on Monday.

China's CSI 300 Index gained 0.2 per cent, while Hong Kong's Hang Seng Index lost 1.4 per cent by the midday break.

The economy grew 4.7 per cent in April-June, official data showed, its slowest since the first quarter of 2023 and missing analysts' forecast of 5.1 per cent growth in a Reuters poll.

"The disappointing second-quarter economic growth in China, which is the first set of quarterly data that is free of distortions by the pandemic, will add pressure on the Chinese government to boost confidence," Vasu Menon, managing director of investment strategy at OCBC.

China's economic growth has been uneven this year, with industrial output outstripping domestic consumption, fanning deflationary risks amid the property downturn and mounting local government debt.

Tech giants listed in Hong Kong slumped 2.4 per cent, while mainland property developers plunged 2.6 per cent. In mainland markets, the tech-focused ChiNext Composite Index lost 1 per cent, while energy shares went up 1.6 per cent.

"We wouldn't say the 5 per cent full-year target is out of reach for now. But more support will be necessary... probably via monetary policy. There could be further short-term rate cuts," said Woei Chen Ho, economist at UOB.

With business, employment and consumer sentiment near record lows, the ongoing four-day plenum will seek to inject confidence in the economy. However, conflicting goals such as boosting growth while cutting debt may mean little progress toward implementing change.

"The market will place a high hope on the third plenum this week. Unfortunately, the structural-oriented party convention is unlikely to unveil counter-cyclical measures," said Zhaopeng Xing, senior China strategist at ANZ.

"The outlook for H2 is unfavourable to China's export-driven growth as trade protectionism grows."

The concerns on export are also elevated as the attack on US presidential candidate Donald Trump made his victory more likely, while it also injected a whole new level of political uncertainty into global financial markets.

"Considering that after Trump is elected, he may continue to impose tariffs on China and then create depreciation pressure on the yuan, the impact on domestic stocks, bonds and exchange rates is bearish," said Zheshang Securities in a note.

Trump's broader imposition of tariffs during his 2017-2021 presidency kicked off a tariff war with China. As a candidate this year, he has floated tariffs of 60 per cent or higher on all Chinese goods and a 10 per cent across-the-board tariffs on goods from all points of origin.
