TORONTO, Oct 9 (Reuters) - Canada's main stock index markedits lowest close in almost two weeks on Tuesday, tracking asell-off in world equity markets after the IMF said the globaleconomic slowdown is worsening.
All 10 of the index's sectors fell on a wave of negativesignals, including the stark warning from the IMF as it cut itsgrowth forecasts for the second time since April and warned U.S.and European policymakers that failure to fix their economies'ills would prolong the slump.
Commodity and financial shares were among the hardest hit.Barrick Gold
sank 3.7 percent to C$39.60, Goldcorp Inc
lost 3.9 percent to C$43.45, and Manulife Financial
fell 3 percent to C$11.95.
"I think the IMF (report) is what people are payingattention to. But it struck me as being a little bit late ...current economic news coming out of the U.S. has been a littlebit better rather than worse," said Ian Nakamoto, director ofresearch at MacDougall, MacDougall & MacTier.
Other news from Europe also kept investors on edge asuncertainty about when Spain will apply for a bailout worriedmarkets, as did concerns about Greece's debt load.
The Toronto Stock Exchange's S&P/TSX composite index
ended down 145.42 points, or 1.17 percent, at12,273.57. It was its weakest close since Sept. 26.
Looking ahead to Wednesday, investors are expected to taketheir cue from U.S. aluminum producer Alcoa Inc
, whichkicked off earnings season after Tuesday's market close. Alcoa'sthird-quarter results beat Wall Street estimates even though itreported a net loss.
Technology shares will also be in the spotlight afterbrokerage downgrades of Intel and other major companies.
Analysts forecast third-quarter earnings of S&P 500
companies will drop 2.3 percent from the year-earlier quarter,according to Thomson Reuters data, which would be the first dropin U.S. quarterly earnings in three years.
"I think people should expect, at best, flat year-over-yearearnings for the third quarter," said Pat McHugh, Canadianequity strategist at Manulife Asset Management.
"The economic cycle began in the middle of 2009, so we're inour third year now. At this stage of the economic cycle,earnings don't grow fast, earnings tend to slow down, profitmargins have rolled over."
