Investors remained nervous about the Federal Reserve’s outlook for raising U.S. interest rates and the uncertainty surrounding Greece’s recent election results.

Choppiness in the price of U.S. crude oil helped send shares of energy producers down 1.1 percent.

The Fed said on Wednesday the U.S. economy was expanding “at a solid pace,” signaling to investors the U.S. central bank was on track to raise rates later this year.

The benchmark TSX, which tumbled about 1.6 percent on Wednesday, slipped to its lowest in a week before rebounding slightly.

“Heightened volatility is going to be a mainstay for 2015, regardless of which direction the markets go,” said Andrew Pyle, senior wealth advisor and portfolio manager at ScotiaMcLeod.

“We’ll probably find fundamentals begin to shift in favor of crude oil this year, and the TSX could outperform U.S. markets,” he added.
