Stocks sold off Wednesday, continuing the sluggish start to September, as concerns mounted that the Federal Reserve may not be done hiking interest rates.
The Dow Jones Industrial Average sank 198.78 points, or 0.57%, to end at 34,443.19. The S&P 500 dropped 0.7% to finish at 4,465.48, while the Nasdaq Composite shed 1.06% to close at 13,872.47.
Treasury yields jumped, weighing on risk assets again. The yield on the 2-year Treasury note was last up about 6 basis points and trading above the 5% level.
Pressured by rates, technology stocks underperformed, with the tech-heavy Nasdaq notching a third straight day of losses. The biggest laggards included Nvidia and Apple, dropping more than 3% each. Along with Apple, Amgen and Boeing fell about 2% each, weighing on the Dow.
Wednesday's rise in Treasury yields coincided with stronger-than-expected economic data that fueled some concern over the likelihood of further hikes. Recent readings on both the services and manufacturing sectors of the U.S. economy show that prices are moving in the wrong direction.
"The ISM reinforced all the concerns that have been bedeviling stocks for weeks – higher yields undercut stock valuations, robust growth [and] sticky inflation keep pressure on the Fed, healthy growth gives a further bid to oil," said Vital Knowledge's Adam Crisafulli in a Wednesday note.
The prices component of the ISM services index rose 2.1 percentage points to 58.9% in August, representing the share of companies reporting increases as well a four-month high.
That follows the prices component of the ISM manufacturing index jumping 5.8 points to 48.4%. While readings below 50% represent contraction in the ISM survey, the big one-month jump is a reversal from the recent trend. The prices paid component rose slightly more than expected, further fueling rate hike fears.
Following the services report, the probability that the Federal Reserve will raise interest rates in November increased. As of Wednesday afternoon, traders are pricing in a greater than 40% probability of a hike in November and a 93% chance that the central bank holds rates steady this month, according to the CME Group.
"Even though we keep hearing that we'll probably be in just a soft patch and not a recession, the more negative news that we get about the economy, the more I think people worry that we could actually fall into a recession," said CFRA Research's chief investment strategist Sam Stovall.
Elsewhere, the latest Beige Book from the Fed indicated that the U.S. economy saw modest growth from in July and August, and slowing price growth.
Earlier in the day, Boston Fed President Susan Collins said the central bank can "proceed cautiously" on more rate hikes, but indicated that "further tightening would be warranted" depending on the data.
