TORONTO (Bloomberg) — Canadian stocks rose for a second day after better-than-expected jobs reports in the US and Canada stoked optimism that the North American economy will propel profit growth.

Research In Motion Ltd. soared after it gave forecasts that exceeded analyst estimates. Teck Cominco Ltd. led materials producers higher on speculation that US demand for resource exports will stay strong. Canadian Tire Corp. paced gains among consumer-related companies as the Canadian dollar surged, making the retailers' international purchasing cheaper.

"The jobs reports added some assurance that things are moving along pretty nicely on the economic front," said Fred Ketchen, senior trader at Scotia McLeod Inc. in Toronto "Research In Motion had a large part to play in this. It's one of those wonderful success stories that continues to grow."

The Standard & Poor's/TSX Composite Index added 108.23, or 0.8 percent, to 14,233.34 in Toronto and notched its fourth-straight weekly gain. The benchmark has recovered three-quarters of the 12 percent that it dropped from its July 19 record on concern a housing slump and tighter credit may tip the US into recession.

Research In Motion rose C$11.30, or 11 percent, to a record C$111.60 Analysts raised their share-price forecasts after the Waterloo, Ontario-based company reported yesterday second-quarter profit that more than doubled as its new handsets fended off a challenge from Apple Inc.'s iPhone. The company's third quarter profit and sales projections exceeded analyst estimates.

Goldman, Sachs & Co. added Research In Motion to its "conviction buy" list and raised its 12-month share-price forecast 39 percent to C$160.18. At least 11 other analysts yesterday raised their target prices.

A gauge of technology shares rose 7.6 percent even as Nortel Networks Corp., its second-largest constituent, dropped 43 cents, or 2.5 percent, to C$16.58. Research In Motion accounts for more than two-thirds of the index's value.
