American Marconi Wireless News - Chinese stocks tumble on stimulus upset, Asia tracks Wall St higher

After blockbuster performances in the wake of last month's announcements to kickstart growth, traders were left deflated after a news conference on Tuesday fell short of expectations and revived worries about the outlook.

A rally on Wall Street, helped by a plunge in oil prices and optimism over the US economy, did little to lift sentiment on Chinese trading floors, though most other markets in Asia enjoyed gains.

Investors are now keeping tabs on developments out of Beijing, after it said Finance Minister Lan Fo'an would hold a Saturday briefing on fiscal policy.

Traders are hoping for more indications about officials' plans, although analysts warn there is unlikely to be the big "bazooka" stimulus akin to the support seen during the global financial crisis.

Shehzad Qazi at China Beige Book said the news conference "underscored that Beijing does not feel the need to do 'whatever it takes'.

"Instead it's opting for targeting stimulus -- including allocating funds for projects previously announced. The irony is markets would've continued rallying had there been no press conference.

"The only upside of (Tuesday's) event was injecting a much needed dose of reality."

Hong Kong had soared more than 20 percent between the first batch of measures being announced and Monday, but it collapsed more than nine percent Tuesday -- its worst day since 2008.

After swinging in the morning, the Hang Seng Index fell more than one percent Wednesday as traders struggled to get back on track.

Shanghai ended down more than six percent -- having seen a 10 percent opening rally Tuesday pared to just over four percent by the end of the day.

Still, most other markets in the region rose as investors took their lead from New York, where tech firms led the way on optimism over the world's top economy in the wake of Friday's forecast-topping jobs data.

Tokyo rose, with Seven & i Holdings -- the owner of the 7-Eleven convenience store chain -- piling on 12 percent after a report said Canada's Alimentation Couche-Tard had hiked its takeover offer for the company by almost 20 percent to $47.2 billion. It later eased back to end almost five percent higher.

Sydney, Singapore, Taipei, Wellington, Bangkok and Mumbai also rose, along with London, while Paris and Frankfurt were flat. Manila and Jakarta dipped.

While the US jobs figures dented expectations for a second successive bumper interest rate cut this month, they did temper worries about a possible recession.

US consumer and producer prices data towards the end of the week should provide further clues on the interest rate outlook, while third-quarter earnings season kicks off on Friday.

Oil prices inched up but made little headway into the losses of almost five percent suffered in the previous session that came on the back of doubts about Chinese demand and after Israel faced international pressure not to strike Iranian crude installations.

Fears about Israel's response to Iran's missile attack last week had sent the commodity soaring Monday to their highest levels since August.

Healthy US stockpiles and expectations of ample supply both in and out of OPEC also weighed on the black gold.
