The Toronto stock market was higher Wednesday as a strong earnings report from aluminum giant Alcoa Inc. raised hopes that the first-quarter earnings season won't be as bad as expected.

U.S. markets were sharply higher after the largest U.S. aluminum manufacturer said Tuesday after the market close that it earned 10 cents a share in the first quarter against expectations of a four cent a share loss.

Alcoa also reaffirmed its forecast of a seven per cent increase in 2012 global aluminum demand and its shares were ahead 8.05 per cent to $10.07 (U.S.) in New York.

But traders have also been nervous about how the first-quarter earnings season will play out.
Analyst expectations for earnings for companies in the Standard & Poor's 500 index went from anticipation of an increase of about three per cent early in the quarter to an expected decline of 0.1 per cent, according to FactSet.
Such a dip would follow three straight years of strong double-digit earnings growth.
"For this cycle, I think we have seen peak earnings, peak profitability," said Paul Vaillancourt , CEO of Canadian Wealth Management in Calgary.
"But companies are not going to start losing money this quarter, it's just the rate of growth will decelerate. And so you won't see the same quarter over quarter, year over year growth in earnings but that's what happens at this stage in the recovery."
He said what is important is that the U.S. economic recovery has become self-sustaining "and that's what really matters."
Tuesday's losses had erased all gains on the TSX for 2012, leaving the main index about 20 points shy of where it started the year.
The European debt crisis continued to be in focus Wednesday as Italy's borrowing costs more than doubled in a couple of bond auctions due to renewed market uncertainty about debt and growth prospects among the 17-country euro zone's weakest members.
The borrowing rates of Italy and other financially shaky countries like Spain had eased in recent months after the European Central Bank gave banks emergency loans and the government of Italian Prime Minister Mario Monti implemented austerity measures.
However, that lending program by the ECB expired at the end of March.
