The Globe and Mail reports in its Wednesday edition that the Nasdaq composite and the S&P 500 finished lower on Tuesday under pressure from technology stocks, while the Dow and Toronto Stock Exchange marked their second straight record closes, while SpaceX rallied to become the fifth-most valuable U.S. company. A Reuters dispatch to The Globe says that after rallying sharply on Monday on optimism about a U.S.-Iran peace deal, investors in the S&P 500 and Nasdaq took a breather even as oil prices fell to their lowest levels since early March. Shares of SpaceX finished up 4.8 per cent at $201.80, after hitting a record high of $225.64 (all figures U.S.). SpaceX ended the session with a market value above that of Amazon and briefly surpassed Microsoft's value. The Dow rose 328.64 points to 51,999.67, the S&P 500 lost 42.94 points to 7,511.35 and Nasdaq lost 307.60 points to 26,376.34. The S&P/TSX Composite Index ended up 113.94 points at 35,389.58, eclipsing the record closing high it posted on Monday. SSR Mining was a standout, jumping 10.2 per cent after the company announced that it had approved an additional $500-million for share repurchases and the reinstatement of a regular quarterly dividend.
