'Market correction' underway

Colin Cieszynski, chief market strategist at CMCMarkets, said investors arefacing "a pretty serious market correction" that began at the start of the new year.

"The world economy is going through a number of major changes right now, particularly reacting to the steep decline we've had in energy prices over the last few months," said Cieszynski.

"It takes time for people to react to the shorter term impacts in the stock market, but there can be some longer-term benefitsas well, such as more money back in the pockets of consumers and businesses. But that takes longer to have a positive effect."
