The Globe and Mail reports in its Wednesday edition that Wall Street indexes lost ground in Tuesday's volatile session as investors swayed between fears of rising oil prices and hopes for a resolution to the U.S.-Israeli war on Iran. A Reuters dispatch to The Globe says President Trump is claiming progress in talks amid reports suggesting that more American troops were headed to the Middle East. U.S. Treasury yields rose on uncertainty about the war and a weak auction of two-year Treasury notes, also adding pressure to equity markets. Canada's main stock index, however, managed to end slightly higher, with higher oil prices lending support. Indexes regained some ground after Mr. Trump told reporters that the United States was talking to "the right people" in Iran in order to reach an agreement to end hostilities and that Iran has agreed they will never have nuclear weapons. But reports that the Pentagon is expected to send thousands more troops from the 82nd Airborne Division to the Middle East caused some concerns the war could drag on and keep oil prices high. The S&P/TSX Composite Index ended up 57.78 points at 31,941.59. The index is down 7.5 per cent from a record closing high on March 2. Gold edged lower.
