U.S. stocks climbed to an almost six-week high amid a rally in some of the world’s largest technology companies.

The S&P 500 extended gains into a fourth day and the Nasdaq 100 posted its biggest advance since April after surging as much as 4.1 per cent. Amazon.com Inc. soared ahead of its Prime Day while Apple Inc. jumped as the tech giant -- whose price target was raised by RBC Capital Markets -- is set to embrace 5G as one of its most significant additions to this year’s iPhones. Twitter Inc. rallied on an upgrade at Deutsche Bank, which also boosted its price estimates for other companies that derive their revenue from digital advertising such as Facebook Inc. and Alphabet Inc.

After plunging into a correction last month, the tech-heavy gauge extended its surge from this year’s lows to more than 70 per cent. Investors have once again turned back to the companies flush with cash that can thrive if the economic recovery slows down. Prospects for a quick end to the stalemate over a new stimulus faded Monday with members of the House being told not to expect any action this week and many Senate Republicans rejecting the White House proposal for a deal.

“People are going back to the trade that’s worked, and that’s the growth trade,” said Keith Gangl, a portfolio manager of Gradient Investments. “People are worried about missing out, so they are going right to the tech leaders.”

The hearings for the Supreme Court nomination of Judge Amy Coney Barrett began Monday in the Senate Judiciary Committee as Republicans try to cement a conservative majority on the court before the Nov. 3 election.

Elsewhere, oil slumped with workers in the U.S. Gulf heading back following Hurricane Delta’s landfall and Libya taking a major step toward reopening its biggest field. The offshore yuan sank after China’s central bank took steps to restrain the currency’s rally. The Treasury market was closed for a U.S. holiday.
