TORONTO - The Toronto stock market moved lower Thursday as oil and metal prices gave up ground in the wake of U.S. economic reports that deepened worries about economic growth for the rest of 2010.

The S&P/TSX composite index fell 70.9 points to 11,710.18 while the TSX Venture Exchange rose 3.38 points to 1,473.35.

The Canadian dollar was down 0.98 of a cent at 96.23 cents US.

Markets were already weak after new applications for unemployment insurance in the United States reached the half-million mark last week for the first time since November, a sign that American employers are cutting jobs again as the recovery slows.

Losses picked up at mid-morning after the U.S. Conference Board said its index of leading economic indicators rose 0.1 per cent last month. The data suggests growth will be sluggish for the rest of the year, following a drop of 0.3 per cent in June. Economists polled by Thomson Reuters had expected a gain of 0.2 per cent.

On top of that, the Federal Reserve Bank of Philadelphia reported that its index of manufacturing activity in the Philadelphia region fell to negative 7.7 in August from 5.1 in July. This was the first negative reading in a year and surprised investors who had been expecting the index to rise to 7.0.

"Everything seems to be pointing to weaker than economists expected," said Ian Nakamoto, director of research at MacDougall, MacDougall and MacTier.

"Most economists are revising down any indicator you want to use. Having said this, the market has been weak since April. It's a matter of, are we going to get some encouraging news?"

There had been better news from Europe earlier in the morning, where Germany's central bank said the economy was on course to grow by about three per cent this year, much higher than the 1.9 per cent pace that the Bundesbank had earlier forecast.

Intel Corp. said the deal highlights that "security is now a fundamental component of online computing." Intel shares declined 69 cents to US$18.90.

The TSX tech sector was the leading gainer, up per cent. But that was largely because of a 16.6 per cent jump in the share price of business software company Open Text Corp. (TSX:OTC). Its shares were up $6.39 to C$44.80 after the company ended its fiscal year by more than doubling its fourth-quarter earnings to $51.5 million.

In other economic news, Statistics Canada's composite leading index, a snapshot of future economic performance, slowed to a 0.4 per cent increase in July, after a gain of 0.7 per cent in June.

Statistics Canada reports most of the slowdown originated in the household sector.

The housing index continued to retreat from its recent highs, declining 4.1 per cent as both housing starts and sales contributed to the decline.
