The end-of-month rebound in global equities faded as investors weighed prospects for fiscal stimulus in the U.S. and the outlook for the coronavirus pandemic. Oil tumbled on concern slow growth will limit demand.

The S&P 500 Index slumped, with more than two stocks falling for every one that advanced, after talks on expanding aid ended for the day with plans to resume discussions tomorrow. An exchange-traded fund that tracks the S&P 500 gained 0.2 per cent in after-hours trading after a study showed a Regeneron Pharmaceuticals Inc. antibody cocktail may help treat coronavirus patients outside of the hospital.

Oil fell toward US$39 a barrel in New York. Treasuries were little changed, while the dollar weakened.

S&P 500 is on track for the worst month since 2018 relative to global peers

With the pandemic’s global death toll exceeding 1 million and virus cases on the upswing in many locales, investors are pinning hopes on a US$2.2 trillion stimulus proposal by Democrats to help support economic growth. End-of-month and end-of-quarter portfolio rebalancing could also be exacerbating market moves as September comes to a close.

“A lot of the fiscal stimulus conversation is driving the markets here in the near-term,” said Brent Schutte, chief investment strategist at Northwestern Mutual Wealth Management. At the same time, there “has been a fear that you’d have a resurgence in cases in the fall and some people have chosen to take their money and sit on the sidelines.”

The negotiations between the Trump administration and congressional Democrats are reaching a critical juncture this week. House Speaker Nancy Pelosi and Treasury Secretary Steven Mnuchin spoke Tuesday morning for 50 minutes and are set to speak again Wednesday.

Markets are also girding for the first presidential debate Tuesday, and traders have pushed up overnight implied volatilities on Mexico’s peso in anticipation of price swings.

Elsewhere, Banks led broad-based declines in the Stoxx Europe 600 index. The MSCI AC Asia Pacific Index was little changed as South Korean shares advanced, while Hong Kong stocks fell. Nippon Telegraph & Telephone Corp. announced plans to turn its wireless carrier unit NTT Docomo Inc. into a wholly owned subsidiary in a US$40 billion buyout. NTT Docomo shares surged by their limit at the close in Tokyo.
