The Canadian stock market dipped lower Thursday, as stocks lost their recent gains and investors got concerned about the upcoming budget battles in the U.S. The S&P/TSX Composite Index subtracted 70.33 points, or 0.56 percent, to 12,470.44, while the S&P/TSX Venture Composite Index lost 13.67 points, or 1.10 percent, to 1,226.17. The euphoria from Tuesday\'s U.S. fiscal cliff deal quickly tapered off in the market Thursday, as traders sobered up to the imminent long slog through the country\'s debt ceiling debates and unresolved budget issues. Meanwhile, Thursday\'s economic data from the U.S. showed contrasting reports in the country\'s private sector job gains and unemployment benefits claims in December. The latest U.S. job report revealed an adding of 215,000 jobs in the private sector last month, better than the 140,000 job gains economists had predicted. However, the U.S. Labor Department said state unemployment benefits claims rose to 372,000 last week, from 350,000 in the week before.
