The drop followed a 270-point rise Thursday on news the U.S. economy grew at an annualized rate of 3.5 per cent in the third quarter, fuelled mainly by government spending.

The energy sub-index was off two per cent as December crude on the New York Mercantile Exchange fell $2.87 to close at $77 US.

However, the telecom sector rose 1.3 per cent a day after the federal broadcast regulator ruled Toronto-based Globalive doesn't meet Canadian ownership requirements and denied it a licence to compete with Canada's three existing cellphone networks.

Gold and the Canadian dollar also fell.

The December bullion contract on the Nymex finished off $6.70 to $1039.70 US an ounce. The loonie ended down 1.29 cents to 92.43 cents US.

In New York, the Dow Jones industrial average settled 249.85 points lower to 9,712.73 after running up 200 points on Thursday.
