London (AFP) - Chinese stocks surged on Monday after officials unveiled further economic stimulus measures, while investor caution weighed on US and European stocks after solid gains chalked up last week.

A profit-warning from auto giant Stellantis and from Britain’s Aston Martin sent shivers through the industry, adding to the temptation to lock in gains on the final trading session of the third quarter.

A week of US labour market data, capped by nonfarm payrolls on Friday, will be closely watched for signs of further interest rate cuts for the world’s largest economy, as will a speech by Federal Reserve chief Jerome Powell on Monday.

Expectations that the Fed has won its war on inflation, giving it room to cut rates even more to boost growth, had sent US indices to record highs last week.

Also on Monday, European Central Bank chief Christine Lagarde welcomed recent inflation slowdowns in several EU countries, saying they “strengthen our confidence that inflation will return to target in a timely manner”.

Many analysts now see the chance of a further ECB rate cut at its October meeting.

“There are no obvious reasons for investors to turn bearish. But there is some caution creeping in as the major indices trade at or near their all-time highs,” said David Morrison, market analyst at Trade Nation.

In Paris, Stellantis – whose brands include Jeep, Fiat and Peugeot – saw its shares plummet 14.7 percent after slashing its operating margin target, citing costs for improving its North America operations and increased Chinese competition.

Britain’s Aston Martin also lowered its financial guidance for 2024, sending its shares down 23 percent.

“Aston Martin is a prime example of how China’s economic woes have been making well-off Chinese consumers more cautious,” said Susannah Streeter, head of money and markets at Hargreaves Lansdown.

“The property crisis has affected perceptions of wealth and put people off buying big-ticket items, like high-end cars,” she said.

Shares in other major carmakers also suffered, with Renault losing 5.6 percent and Volkswagen 3.1 percent.

In Asia, Shanghai’s stock market jumped more than eight percent – its best day since 2008 – while Hong Kong briefly leapt around four percent, a day before Chinese markets shut for the Golden Week holiday.

They extended a rally begun last week as Chinese officials announced fiscal measures, notably interest-rate cuts and eased rules on buying homes, aimed at igniting growth in the world’s second-biggest economy.

Developers were among the best performers in Hong Kong, with Kaisa rocketing more than 80 percent, Sunac jumping over 55 percent and Agile Group up 19 percent.

“The Chinese stock market rally will take a breather during the October holiday, which will give investors time to take stock and to decide whether the Asian powerhouse’s shares have further to run,” said Kathleen Brooks, research director at XTB.

But elsewhere in Asia, Tokyo stocks dropped nearly five percent on expectations incoming prime minister Shigeru Ishiba would pursue policies keeping the yen strong – which would weigh on Japanese exporters.
