The Dow Jones industrial average fell 61 points or 0.5 per cent, to 13,063. The broader S&P 500 fell 8 points or 0.5 per cent, to 1,395. In Canada, the S&P/TSX composite index fell 51 points or 0.4 per cent, to 12,386.

U.S. initial jobless claims were in line with expectations, falling slightly to 348,000 for the period ended last week – another good sign for the employment situation, but not enough to lift investor sentiment by much.
