The main TSX index has gained just shy of four per cent since the start of the year, extending the steep climb made over the past five years. Those levels have put the stock market at a point where it will likely hold steady for the time being, said Kash Pashootan, portfolio manager at Ottawa-based First Avenue Advisory.
"It's reasonable to expect it to go sideways here for the short term," he said.
"The reality of the future is we're going to see more volatility than we're used to and less in the way of returns."
Overseas, China announced a 50 per cent cut in import duties on a number of consumer products in a move to spur consumer spending and revitalize its slowing economic growth.

"Expanding domestic consumer demand is an important measure for steady growth and structural adjustment," China's Finance Department said.
