TORONTO (Reuters) - Toronto's main stock index
closed higher Wednesday, swinging back from a five-week low
hit earlier in the day, as gold prices climbed and Canadian
Imperial Bank of Commerce unveiled results that topped
market expectations.

Big names on the upside included gold miners Barrick Gold
, up 3.3 percent at C$47.96, and Goldcorp, which
soared 3.7 percent to C$44.60 as the price of bullion rose.
The index's materials sector, home to fertilizer
companies and miners, rose 2 percent.

Financials gained as CIBC reported a strong third-quarter
profit, relieving some concern about bank results after Bank of
Montreal reported a weaker-than-expected profit on Tuesday.
Shares of CIBC, the top net gainer on the market, climbed 4.9

or 0.85 percent, higher at 678.33.

Earlier in the session it hit its lowest point since July
21 at 11,469.25 on gathering worries over the outlook for the
global economy, underscored by U.S. data.

New U.S. home sales hit a record low in July and orders for
durable goods were weak, heightening fears the U.S. economy was
at risk of a new downturn.

The economic weakness was a key factor driving up the price
of gold as a safe-haven play, said RBC's Johnston.

"There's an element of fear creeping back into the system.

decliner, dropped 2.1 percent to C$154.51 as BHP Billiton
tried to damp expectations it would sweeten its
hostile $39-billion $130-a-share offer for the world's largest
