LONDON, May 6 (Reuters) - World stocks rose close to the previous day's near 4-month high on Wednesday, helped by better-than-expected results from BNP Paribas and euro zone data showing firmer services business activity.
Oil and other risky assets also pushed higher, while the low-yielding yen jumped after a source familiar with the result of a U.S. banking stress test told Reuters Bank of America <BAC.N> needed as much as $34 billion in extra capital.
Concerns about U.S. banks linger, but forecast-beating first-quarter profits at French bank BNP Paribas <BNPP.PA> helped the benchmark MSCI world equity index <.MIWD00000PUS> reverse early losses to add to gains after rallying more than 30 percent since mid-March.
Also driving risk appetite, the Volatility Index <.VIX> -- Wall Street's fear gauge -- hit its lowest level since late September, just after Lehman Brothers collapsed.
Furthermore, a key index of euro zone services business activity staged its biggest one-month rise since December 2001 and firms were even more optimistic about the future, according to Markit.
"A general feeling of well being is being felt across the markets, with the joyous cries of the bulls beginning to drown out the doom mongers," said Chris Hossain, senior sales manager at ODL Securities.
"As we approach half way through the week, it will be interesting to note how the banking stress test and the non-farm payroll figures will impact on sentiment in the latter part of the trading week." The MSCI world equity index was up 0.1 percent on the day, after hitting its highest level since January on Wednesday. The index is now in positive territory for the year, gaining 2.9 percent since early January.
The FTSEurofirst 300 index <
> rose 0.3 percent on the day while emerging stocks <.MSCIEF> rose 0.5 percent.U.S. stock futures <SPc1> were pointing to a weaker open on Wall Street. Bank of America fell 10 percent in premarket trade.
Citigroup <C.N> fell after the New York Times reported the bank may have to raise $5-10 billion in new capital in order to meet a government requirement.
