The Globe and Mail reports in its Thursday edition that the U.S. stock indexes fell sharply Wednesday, with chipmaker shares extending recent declines and investors increasingly concerned about renewed U.S.-Iran tensions. A Reuters dispatch to The Globe says losses were milder in Toronto, as energy shares rose in response to a spike in oil prices.

An index of semiconductors fell 3.6 per cent, with Nvidia and Broadcom among the biggest drags on the S&P 500. Investors were still taking some tech profits, said Tom Hainlin, an investment strategist in Minneapolis. Also, investors are now "pricing in maybe a higher interest rate" after recent economic data and are also worried about the war dragging on till the fall. The S&P/TSX Composite Index ended down 260.37 points at 34,151.32, marking its lowest closing level since May 19. The energy sector rose 1.6 per cent, as the price of oil settled 2.1 per cent higher at $90.03 (U.S.) a barrel. The price of gold was down 4.4 per cent.
