The S&P/TSX Composite Index edged above 37,000 on Wednesday and was on track for another record high, supported by bank earnings. BMO rose 0.3% and Scotiabank gained 2% after reporting stronger-than-expected quarterly results on Tuesday. RBC, TD Bank and CIBC are scheduled to report on Thursday. National Bank fell nearly 5% despite posting third-quarter profit above expectations. Energy stocks advanced even as oil prices declined amid renewed talks between Iran and Oman, with prices still elevated and prospects for a US-Iran peace deal uncertain. Canadian Natural, Suncor and Cenovus each gained about 1%. Miners mostly fell as gold prices slipped after US PCE data exceeded forecasts, increasing expectations for a Federal Reserve rate hike. Agnico Eagle, Barrick and Franco-Nevada dropped more than 1%, while WPM lost over 2%.
