Wall Street posts gains as investors eye rate outlook

US stock market: Wall Street's main indexes posted gains on Monday, with increases in Amazon.com shares and the energy sector, as Treasury yields rose further and investors looked to economic data and Federal Reserve policymakers' remarks later in the week for clarity on the path for interest rates. Investors are grappling with the rise in benchmark Treasury yields to 16-year highs after the Fed gave a hawkish longer-term rate outlook. The S&P 500 rebounded on Monday after last week it had its biggest weekly drop since March.

There is a "tug of war between investors seemingly getting more concerned about 'higher for longer' ... and bulls wondering maybe we have seen the correction and we can start to build from these levels higher," said Chuck Carlson, chief executive officer at Horizon Investment Services. The Dow Jones Industrial Average (.DJI) rose 43.04 points, or 0.13 per cent, to 34,006.88; the S&P 500 (.SPX) gained 17.38 points, or 0.40 per cent, at 4,337.44; and the Nasdaq Composite (.IXIC) added 59.51 points, or 0.45 per cent, at 13,271.32.

Among S&P 500 sectors, energy (.SPNY) led the way, rising 1.3 per cent, while materials (.SPLRCM) gained 0.8 per cent. Defensive sectors lagged, with the consumer staples (.SPLRCS) group dropping 0.4 per cent. With the end of the third quarter drawing near, investors said market moves may be relatively muted until companies report quarterly results in the coming weeks.

The S&P 500 has slid about 5.5 per cent since late July but remains up about 13 per cent for 2023. "There is less urgency to aggressively buy pullbacks in a higher-for-longer world and that is what the market is going to have to deal with over the coming months," said Angelo Kourkafas, senior investment strategist at Edward Jones.

Investors through the week will be monitoring data including on durable goods and the personal consumption expenditures price index for August, and second-quarter Gross Domestic Product, as well as remarks by Fed policymakers, including Chair Jerome Powell. Chicago Fed President Austan Goolsbee said in an interview with CNBC on Monday that inflation staying above the Fed's 2 per cent target remains a greater risk than tight central bank policy slowing the economy more than needed.

In company news, Amazon.com (AMZN.O) shares rose 1.7 per cent after the e-commerce giant said it will invest up to $4 billion in startup Anthropic to compete with growing cloud rivals in artificial intelligence.
