U.S. stocks advanced for the third quarter in a row as investors weighed the latest turns in the trade war between the world’s two largest economies. The dollar rose and Treasuries edged higher.

The S&P 500 gained for a third month out of the last four after rebounding from August’s downturn. Tech fueled the rise after the Trump administration partially refuted a report it would target Chinese capital, reversing losses sparked by the news Friday.

Ten-year Treasury yields erased an early advance to trade lower around 1.67%, more than 30 basis points lower than it was at the end of June, after data showed weakening business activity. The dollar pushed quarterly gains toward 2.7%.

The pound fell as Prime Minister Boris Johnson fought off allegations of sexual impropriety and plots in Parliament to oust him over his Brexit plans. West Texas oil fell below $55 a barrel. Gold dipped for a second day, though it was still set for a fourth quarterly gain.

“Investors continue to be people who are pulling petals off a daisy saying ‘there will be an accord, there won’t be an accord, there will be an accord, there won’t be.’ Nobody really knows for sure -- at least I don’t,” Sam Stovall, chief investment strategist at CFRA, said about trade between the U.S. and China in a phone interview.

“Based on the market’s lack of fear, the majority expect some sort of discussion to occur October 10th and that there will be encouraging developments as we move forward.”

The month is finishing much as it began, with foreign-trade uncertainty once again muddying the outlook for investors.

Citigroup said that restricting access to U.S. finance would amount America’s most extreme potential move against China, while a Treasury official said over the weekend that the U.S. has no plans “at this time” to stop Chinese companies from listing on American exchanges. Beijing on Monday vowed to keep opening up its financial markets and encouraging foreign investment, and released a positive report on manufacturing.

Elsewhere, Chinese equities fell in the final session before a week-long holiday. Financial markets and offices in Taipei closed Monday due to the approach of Typhoon Mitag.
