On Wall Street, stocks mostly rose on Tuesday on a report that European leaders might create a second bailout fund to supplement the one they have already agreed to. The second fund would nearly double the capacity of Europe's financial rescue programs, the Financial Times reported.
The plan involves allowing the existing €440bn bailout fund to continue running when a new €500bn facility comes into force in mid-2012, almost doubling the rescue system's firepower, Stan Shamu of IG Markets wrote in a report. "This latest move might just be the 'bazooka' Europe needs to appease markets."

Trading volume was light in Hong Kong, where a slew of IPOs devoured much of the available investment funds and sentiment leaned toward caution as the end of the year approaches.
"I think a lot of people, a lot of funds, have effectively closed their books for the year and are trying to protect the gains that they made, and also a lot of retail money is tied up in IPOs, so it makes for thin trading," said Andrew Sullivan, principal sales trader at Piper Jaffray in Hong Kong.
Asian stocks tumbled Tuesday, hours after Standard & Poor's credit ratings agency warned that it might downgrade 15 of the 17 countries that use the euro - even Germany, which has a top AAA rating and Europe's strongest economy.
On Tuesday, S&P said it might also cut the AAA rating of Europe's bailout fund. The fund needs that top rating to cheaply raise money, and losing it would mean it would cost billions more to fund bailouts.
