Energy selloff drags TSX lower amid market jitters

By John Tilak TORONTO (Reuters) – Canada's main stock index dropped on Thursday as investor nervousness with recent gains sparked a selloff in energy shares, one of the best performing sectors this year, and weighed down broader sentiment. Investors also dissected congressional testimony by U.S. Federal Reserve Chair Janet Yellen, who urged the U.S. Congress to address the nation's long-term budget challenges, warning that the current course was unsustainable. \"The market is extremely volatile,\" said Marcus Xu, portfolio manager at MY Capital Management Corp in Vancouver. The Toronto Stock Exchange's S&P/TSX composite index <.GSPTSE> closed down 110.37 points, or 0.75 percent, at 14,546.03.
