Stock market today: S&P 500 posts back-to-back losses for first time since September as rally stalls

McDonald’s (MCD) shares sank around 10% in after-hours trading on Tuesday after the Centers for Disease Control and Prevention (CDC) said the company’s quarter pounders had been linked to an E. coli outbreak in some states, with most illnesses in Colorado and Nebraska.

“This is a fast-moving outbreak investigation,” the CDC wrote on its website. “Most sick people are reporting eating Quarter Pounder hamburgers from McDonald’s and investigators are working quickly to confirm which food ingredient is contaminated.”

Per the CDC, McDonald’s has stopped using fresh slivered onions and quarter-pound beef patties in certain states while a source of illness is confirmed.

Starbucks (SBUX) just pre-announced its earnings results, and they are very ugly.

Having gotten to know new Starbucks CEO Brian Niccol the past decade, this much I can say confidently:

The benchmark S&P 500 (^GSPC) saw its first back-to-back negative days since Sept. 6 after the index closed just below the flatline on Tuesday.

Matching the S&P 500, the Dow Jones Industrial Average (^DJI) also closed below the flatline while the tech-heavy Nasdaq Composite (^IXIC) ticked up around 0.2%.

Yahoo Finance’s Anjalee Khemlani reports:

Walmart (WMT) announced Tuesday it will offer same-day prescription delivery services in six states, with a plan to roll out to all 49 states in which it operates a pharmacy by January.

The first six states are Arkansas, Missouri, New York, Nevada, South Carolina, and Wisconsin. North Dakota is the only state where Walmart doesn’t operate a pharmacy.

The move brings Walmart into the competitive field of online pharmacies and same-day retail deliveries, with players like Amazon (AMZN) Pharmacy, Walgreens (WBA), and CVS (CVS).

The new service is being integrated into the existing Walmart delivery service, where patients can add their prescription to their cart along with other items — a key differentiator, according to Walmart — and schedule a delivery time. It will apply any new or existing prescriptions and insurance coverage as if the patient were coming to the store to pick it up, Walmart said in its announcement.

Shares moved about 2% higher in late afternoon trading.

Trump Media & Technology Group stock (DJT) hit its highest level since July on Tuesday, rising as much as 10% as investors bet on former President Donald Trump’s improved odds of winning the November election in exactly two weeks.

Shares in the company, the home of the Republican nominee’s social media platform Truth Social, have seen a recent surge as both domestic and overseas betting markets shift in favor of a Trump victory, with prediction sites like Polymarket, PredictIt, and Kalshi all showing Trump’s presidential chances ahead of those of Democratic nominee and current Vice President Kamala Harris.

National average polls, however, show both candidates in an incredibly tight race, especially in key battleground states like Pennsylvania and Michigan, which are likely to decide the fate of the election.

Trump Media went public on the Nasdaq in late March after merging with special purpose acquisition company Digital World Acquisition Corp. But the stock has been on a bumpy ride since, with shares oscillating between highs and lows as the moves have typically been tied to a volatile news cycle.

Over the past six months, the stock has been off around 8% — a massive improvement on the heels of the rally after shares hit their lowest point last month.

Trump maintains a roughly 60% interest in DJT. At current levels of above $33 a share, Trump Media boasts a market cap of about $6.7 billion, giving the former president a stake worth around $4 billion. Right after the company’s public debut, Trump’s stake was worth just over $4.5 billion.

Energy (XLE), Consumer Staples (XLP), and Real Estate (XLRE) led Tuesday’s sector action, with markets retreating for their second straight session as traders priced in a higher for longer policy stance from the Federal Reserve.

Oil prices were a standout, with WTI crude (CL=F) rising about 3% to trade above $72.50 a barrel. Brent crude (BZ=F), the international benchmark, rose more than 2% to trade just above $76 a barrel.

Information Technology (XLI), Materials (XLB), and Consumer Discretionary (XLY) served as the day’s biggest laggards.

Yahoo Finance’s Jennifer Schonberger reports:

The International Monetary Fund said Tuesday that the global economy is on pace for a soft landing this year and 2025 but elections around the world introduce a “high” level of uncertainty to that outlook due to potential changes in trade and fiscal policy.

The IMF said an increase in global tariffs could exacerbate trade tensions, disrupt global supply chains, and weigh down medium-term growth prospects by limiting positive spillovers from innovation and technology transfer that once fueled growth in emerging markets and developing economies.

Treasury yields spiked over the last month amid a slew of stronger-than-expected economic data and signs that inflation’s path down toward the Fed’s 2% goal may take longer than initially hoped.

The data has pushed the 10-year Treasury yield (^TNX) up nearly 50 basis points in the past month to hover near 4.2%, its highest level since July. As our graph below shows, the debate among investors appears to be more about how quickly the Fed will reduce interest rates over the next year than whether the central bank will cut once again in November.

As of Tuesday morning, markets were still pricing in a roughly 88% chance that the Fed cuts rates at its November meeting, per the CME FedWatch Tool. But by the end of next year, markets see the Fed likely making one less cut than was priced in on Oct. 4 and two less cuts than markets were projecting on Sept. 18, the day the Fed slashed rates by half a percentage point.

General Motors (GM) stock rose more than 7% on Tuesday morning as the automaker boosted its profitability guidance for a third time this year.

The company booked adjusted earnings per share of $2.96, far outstripping expectations of $2.44. It reported EBIT-adjusted profit of $4.115 billion, up 15.5% from a year ago, with EBIT-adjusted margin climbing to 8.4% from 8.1% year over year.
