TORONTO, Jan 29 (Reuters) - Toronto's main stock index sank 1.6 percent on Friday to close at its lowest level in three months, pressured by weak commodity prices after stronger than expected U.S. economic data sparked a rally in the greenback.
The heavyweight energy and materials sectors were among two of the big drags on the index, down 1.2 percent and 3.5 percent respectively, as prices for crude oil and gold drove lower. [O/R] [GOL/]
