The stock market pulled back in August after a five-month rally. Energy was the only positive sector, thanks to rising oil prices.
The S&P 500 was down 5.5 percent at its low on August 18, but rebounded to end the month with a 1.8 percent decline. More than two-thirds of the index’s members lost value as a lack of catalysts sidelined buyers. Still, the index held its June low and remained above its peak from August 2022. Has old resistance become new support?
Higher borrowing costs weighed on the market in August. The yield on the 10-year Treasury note climbed to its highest level since November 2007 as the government issued new debt and strong economic data reduced the odds of rate cuts soon. However, yields reversed after forming a potential “double top” pattern. Further downside in yields could support stocks.
Last month also saw big drops in sentiment gauges published by the American Association of Individual Investors and the National Association of Active Investment Managers. That may suggest money remains on the sidelines, with potentially limited selling pressure.

Energy stocks quietly pushed higher as tightening inventories lifted crude-oil prices. The sector could remain in focus with Saudi Arabia continuing to limit exports.
There are several potentially important events this month. The week beginning on September 11 is especially active. Apple (AAPL) is expected to unveil new iPhones and key inflation numbers are due. The following week brings an important Fed meeting. See the table below for more.
