TORONTO, Oct 30 (Reuters) - Toronto's main stock index fell hard on Friday afternoon, unwinding nearly all of the previous session's rally, as its two big resource-based sectors each dropped more than 3 percent.
Declines were heavy in Suncor Energy (SU.TO), Barrick Gold (ABX.TO) and other commodity-based issues, which account for more than 40 percent of the index's weighting. The fall was induced by softening prices for oil and gold, as well as profit-taking after the index's 269-point rally on Thursday.
The S&P/TSX composite index .GSPTSE was down 223.87 points, or 2.02 percent, at 10,851.35. (Reporting by Ka Yan Ng; editing by Peter Galloway)
