Star Metro - Stocks mostly up before key US inflation data

Equities also found support on growing optimism over China's economic reopening.

Wall Street had provided a strong lead, with the S&P 500 and Nasdaq soaring Wednesday thanks to demand for recently beaten-down tech firms.

The US consumer price index (CPI) reading due Thursday is the key event for investors, though analysts warned that an above-forecast reading would deal a hefty blow to confidence on trading floors.

The data "could determine whether the relatively positive sentiment seen so far in 2023 can be maintained, given the influence this data point has on the Federal Reserve's interest rate policy", said Russ Mould, investment research director at British brokerage AJ Bell.

Stock market gains were also helped by comments from Fed official Susan Collins backing a quarter-point US rate hike at the bank's next policy decision on February 1.

Collins, who is head of the Boston Fed, told The New York Times that slowing the pace of increases would give policymakers a chance to see how their efforts to rein in decades-high inflation were working.

Investors are also keeping tabs on developments in China as it emerges from years of strict zero-Covid containment measures.

While the long-term outlook remains positive, soaring infections across the country are leading to worries about the effect on economic activity.

World oil prices also jumped on expectations of rebounding Chinese energy demand.

"Energy traders should get used to seeing oil prices head higher," said Oanda analyst Edward Moya. "Oil demand is coming back and expectations are high that China's demand is about to skyrocket."

Several oil experts have tipped prices to hit $100 a barrel this year, with top hedge fund manager Pierre Andurand predicting last week that it could pass $140.
