Stocks edged lower on Tuesday as the S&P 500 wrapped up its seventh-straight month of gains at just below all-time highs.

The S&P 500 lost 0.13% to finish at 4,522.68. Tuesday marked the last trading day of August and the S&P 500 rose 2.9% this month.

For the S&P 500, this is the longest winning streak since a 10-month run ending in December 2017. August was also the benchmark’s 9th positive month in the last 10. The index notched its 53rd record close of 2021 on Monday, and some on Wall Street believe more upside is ahead.

Investors are awaiting a key jobs report on Friday ahead of the Labor Day weekend. Economists polled by Dow Jones expect 750,000 jobs were created in August and the unemployment rate fell to 5.2%.

U.S. stocks slipped Tuesday but posted gains for the month, buoyed by continued investor optimism even amid uncertainty surrounding the Delta variant of the coronavirus.

The Nasdaq Composite was down just 0.04% to 15,259.24. The Nasdaq Composite added 4% for August, its third consecutive monthly win.

Zoom shares fell about 16% on Tuesday after the video-conferencing software company showed slowing revenue growth in the second quarter, weighing on the Nasdaq. Shares of Apple also declined, but Amazon’s stock rose 1% to help offset those losses for the broader markets.

Stocks spent most of August largely drifting higher, lifted by strong second-quarter earnings results and thin trading volumes. Throughout the month, all three indexes notched multiple records. Most recently, investors emerged with fresh optimism after Federal Reserve Chairman Jerome Powell emphasized again that the central bank shouldn’t overreact to this year’s inflation surge.
