TORONTO, March 13 (Reuters) - Toronto's main stock index ended a volatile session with a slight gain on Friday as shares of gold-miners rallied around higher bullion while financials continued to take comfort on news that the U.S. banking sector is finding stability.
After a massive three-day rally where the index surged 9.5 percent, investors decided to take their foot off the gas pedal in the latest session.
But a push higher by gold-mining stocks was enough to carry the overall index a slim gain as a weaker U.S. dollar helped boost demand for the yellow metal.
Gold XAU= also firmed to around $928 an ounce on a combination of technical buying and fears that a Swiss example would lead to a series of currency devaluations.
