US stocks gained ground Friday, posting strong weekly wins after Wall Street's expectations for a jumbo interest rate cut by the Federal Reserve shot up suddenly.

The S&P 500 (^GSPC) rose 0.5% while the tech-heavy Nasdaq Composite (^IXIC) climbed 0.7%, registering a fifth day of gains for both gauges amid a comeback for tech stocks. The Dow Jones Industrial Average (^DJI) added 0.5% or about 300 points.

Near the end of a press conference near Los Angeles on Friday afternoon, Donald Trump was asked about the waning shares of his social media company and whether he’s selling his shares.

No, he quickly promised. He wasn't selling, reports Yahoo Finance's Ben Werschkul.

The comment immediately pushing up shares in Trump Media & Technology Group (DJT) by 10% at one point Friday afternoon. DJT is the publicly traded parent company behind Truth Social.

“I'm not leaving, I love it,” he told reporters during an answer where he repeatedly reiterated what he says are his plans to both stay posting on his Truth Social account and also keep possession of his shares.

Trump has been subject to a lockup period on his stake in the company but that ends next week, on Sept. 19, when the GOP nominee could potentially begin to sell. In unwinding his position, Trump would gain access to what could be a multibillion-dollar windfall — but it's a fallout that is nevertheless down over 70% from it’s peak earlier in the election season.

“A lot of people think I'm going,” he said at another point, saying Elon Musk, who has endorsed Trump, would love to see him switch over completely to X, but he plans to stay where he is.

A hugely important Fed meeting is only days away, marking a significant policy shift and an official end to a years-long tightening campaign designed to tamp down inflation.

What has been months in the making is now only days away. And while the central bank is widely expected to begin cutting rates at the end of their policy huddle on Wednesday, what's less certain is the size of the cut.

Market bets are now roughly split on whether the Fed will ease rates by a more drastic 50 basis points or by 25 basis points. The more severe cut would come in an effort to protect a weakening labor market and minimize the risks of a recession, but would also risk spooking the stock market and signaling a more serious downturn.

On the corporate front, only a handful of companies are set to report earnings, including FedEx (FDX), General Mills (GIS), and Darden (DRI).

Yahoo Finance's Brent Sanchez has a graphical breakdown of what to watch next week:

"We believe what the Fed should do next week is clear: recalibrate the policy rate 50bp lower to adjust for the shifting balance of risks," wrote JPMorgan analyst Michael Feroli in a preview note on Friday.

Friday saw a rise in expectations for a jumbo rate cut by central bankers, according to the CME FedWatch Tool, following reports by the Financial Times and the Wall Street Journal that policymakers were struggling to come to a decision. Investors now place a roughly 49% probability on a 50 basis point cut at the Fed's meeting next week, compared with 15% at one point on Thursday.

Feroli said the Fed should "front-load" its rate cuts since it will take almost a year to get back to the right interest rate policy if central bankers ease rates by 25 basis points each time. In addition, Feroli wrote, "With hindsight, it might have been appropriate to start the cycle in late July."

Still, as Yahoo Finance's Josh Schafer reports, there are reasons for the Fed to pursue a more moderate approach, primarily for the dire signal a 50 basis point cut might send to Wall Street.

But Feroli has a response to this line of thinking.

"The Committee may be worried about sending an overly worried message about the outlook. Powell has proven himself to be an adept communicator and we believe he can convey that a level shift lower in rates is intended to reinforce their forecast for a soft landing."

Here are some of the stocks leading Yahoo Finance’s trending tickers page during afternoon trading on Friday:

Boeing (BA) Shares of the planemaker pulled back as factory workers walked out on strike, halting manufacturing across the company's Seattle hub, its largest. The credit rating agency Fitch said Friday that an extended work stoppage could pose a risk of a credit rating downgrade and affect the Boeing's operations.

Adobe (ADBE): The software company sank in afternoon trading after disclosing an outlook that failed to show an uplift from its AI push. Shares slipped nearly 9%.

RH (RH): Shares of the furniture retailer surged more than 20% Friday afternoon, building on momentum from Thursday when the company reported revenue and earnings that topped estimates.

Oracle (ORCL): The database software and cloud company rose 1% after boosting its fiscal 2026 forecast and announcing that it expects sales in fiscal 2029 to top $104 billion.

As Boeing's West Coast factory workers initiated a strike on Friday, Fitch said that an extended work stoppage could pose a risk of a credit rating downgrade and affect the planemaker's operations.

Boeing shares fell almost 4% in afternoon trading Friday as factory workers began a strike for the first time in 16 years, following a vote of its largest union to reject a contract offer for workers of the company's Seattle hub.

The labor dispute comes as Boeing is still reeling from heightened regulatory scrutiny after a high-profile January incident in which a door panel of a 737 MAX jet detached mid-flight.

If the strike continues beyond several weeks, Fitch said Boeing's management would likely need to find new sources of liquidity to stay within its cash targets and within the credit rating agency's levels before a potential downgrade, Reuters reported.

On the upside, if the parties resolve the strike before a two-week period, the labor action is unlikely to prompt a change in rating, Fitch said.

US stocks gained momentum on Friday afternoon as expectations of a larger cut from the Federal Reserve shot up to about 43%, according to the CME FedWatch tool.

The S&P 500 (^GSPC) and the tech-heavy Nasdaq Composite (^IXIC) climbed 0.7% to point to a fifth day of gains for both gauges amid a comeback for tech stocks. The Dow Jones Industrial Average (^DJI) also added 1% or more than 400 points.

The mood on Wall Street has shifted as traders see a higher likelihood that the Fed will opt for a larger, half percentage point rate cut next week, shifting expectations that had previously settled around a more modest one-quarter cut.

The odds of a 0.5% reduction jumped amid reports by the Financial Times and the Wall Street Journal that the size of the Fed's Sept. 18 decision will be a close call. Adding to the debate, influential former New York Fed president Bill Dudley said there's a "strong case" for a deeper cut.

During morning trading on Friday, the likelihood of a more severe cut of 50 basis points stood at 43%, while the chances of a more traditional 25 basis point reduction registered 57%, according to the CME FedWatch tool. The odds were closer to 50-50 earlier in the trading session, but the likelihood of a larger cut was still much higher on Friday compared to a day ago, when it was was 28%, and to the forecast a week ago of 30%.

US consumers sentiment improved for the second straight month, reaching levels last seen in May and rising about 2% higher than last month's reading.

The first September report of the University of Michigan Consumer Sentiment Index showed a reading of 69, driven in part by the perception that prices are becoming more favorable to consumers. The commonly followed measure of consumer confidence in the US economy is far above the June 2022 low, which registered about 40% worse.

However, "Consumers remain guarded as the looming election continues to generate substantial uncertainty," said Joanne Hsu, surveys of consumers director, in a statement published Friday.

Inflation expectations for the year ahead also improved, continuing a four month trend of optimism that pricing pressures will cool, according to the report. The current reading of 2.7% is the lowest since December 2020, the report said, coming in a range that was seen in the years prior to the pandemic.

Longer-run expectations however, were little changed, ticking up to 3.1% from last month's 3%. They remain "modestly elevated" compared to the years before the pandemic, suggesting that consumer perceptions are are still impacted by the global health crisis and the inflation that followed in the aftermath.

US stocks edged higher on Friday, setting the stage for strong weekly wins after Wall Street's expectations for a more drastic interest rate cut by the Federal Reserve shot up overnight.

The S&P 500 (^GSPC) moved up about 0.2% while the tech-heavy Nasdaq Composite (^IXIC) climbed just over the flat line to point to a fifth day of gains for both gauges amid a comeback for tech stocks. The Dow Jones Industrial Average (^DJI) also added roughly 0.2%.
