S&P 500 erases huge losses after Trump vows “flexibility” on upcoming tariffs

Stocks opened deep in the red, but erased nearly all their losses after President Donald Trump said there would be some “flexibility” on tariffs he plans to enact on April 2.

Buoyed by a late charge (likely influenced by the triple-witching expiry of stock, index, and ETF options), the S&P 500 managed to close marginally higher and the Nasdaq 100 booked a 0.4% gain, while the Russell 2000 dipped 0.6%.

The benchmark US stock index posted its first weekly gain since Valentine’s Day.

The S&P 500 sector ETFs home to the Magnificent 7 (communication services, consumer discretionary, and tech) were the only ones to go positive on the day.

Most S&P 500 constituents fell: in fact, going back to 1997, there have only been eight other sessions where the advance-decline was this negative and the benchmark stock index gained on the day.

Super Micro Computer was the top performer on the S&P 500 after the server company was upgraded by JPMorgan.

Tesla was also a standout gainer, as CEO Elon Musk’s all-hands meeting seemingly offset the negative fundamental headlines that have piled up around the company, at least for one day.

Boeing took flight while Lockheed Martin swooned after Reuters reported that the former beat out the latter for a contract to build a new jet for the Air Force.

Nike floundered after warning of sales declines going forward, at one point erasing all the stock’s gains since October 2015.

FedEx tumbled after missing on earnings and saying profits would be down this year.

Micron’s margin pressure was front-of-mind for traders selling off the stock despite its solid quarterly results.

Carnival dipped after its near-term guidance came in a little light relative to the Street’s estimates.

Chinese EV maker Nio also took the red pill after whiffing on earnings and issuing sales and delivery guidance for Q1 way below analysts’ projections.

Tesla jumps after Elon Musk discloses buying 2.57 million shares, worth more than $1 billion

Tesla soared in early trading on Monday after CEO Elon Musk disclosed a purchase of 2.57 million shares in the company, according to a new SEC filing.

Per the filing, the "Elon Musk Revocable Trust,” for which the Tesla and SpaceX chief is the trustee, reported acquiring 2.57 million shares, taking its total ownership to 413.36 million shares as of September 12, 2025. The block of equity was bought at prices ranging from $371.38 to $396.54.

Earlier this month, the board of directors proposed an eye-watering pay package that could award the tech billionaire up to $1 trillion, assuming that very ambitious market cap and fundamental milestones are met.

Hims & Hers falls after FDA commissioner says its Super Bowl ad breached regulations

Hims & Hers is falling in premarket trading after its Super Bowl ad from February was singled out as the “most overt” example of “brazen” marketing tactics among online pharmacies by FDA Commissioner Marty Makary.

The claim, made in an opinion piece written by Makary and published in the JAMA Network on Friday, highlighted the agency’s stricter enforcement policies on pharmaceutical advertisements.

“Equally brazen, online pharmacies are advertising drugs with only upsides mentioned, contributing to America’s culture of overreliance on pharmaceuticals for health,” wrote Makary. “This breach of FDA regulation was most overt earlier this year when Hims & Hers ran a Super Bowl ad highlighting the benefits of glucagon-like peptide-1 drugs without any mention of side effects or disclaimers.”

Hims’ Super Bowl ad touted its direct-to-consumer weight loss medications as “life-changing,” “affordable,” and “doctor-trusted,” billing its approach as “the future of healthcare.”

Google searches for the company spiked after the ad appeared during The Big Game.

Last week, President Donald Trump issued an executive order directing the Secretary of Health and Human Services to crack down on TV drug ads. It was initially unclear whether that order applied to telehealth companies.

Compounded drugs aren’t subject to the same regulatory burdens over their advertisements as branded, FDA-approved drugs made by pharmaceutical companies. For example, Hims can advertise generic Prozac for climax control (an off-label use) while the company that made the drug, Eli Lilly, cannot.

Nvidia falls after Chinese regulator said it violated the country’s antitrust laws in 2020 deal

Nvidia dropped as much as 2.9% in early trading on Monday after China's State Administration for Market Regulation ruled that the chipmaker violated the country's antitrust laws after acquiring Mellanox Technologies, an Israeli-American network solutions supplier.

In 2020, Beijing approved Nvidia's ~$7 billion acquisition under the condition that the chipmaker would not discriminate against Chinese companies. Since then, Nvidia has had to redesign its chips to comply with the US government's regulations that temporarily banned the company from selling its advanced chips, including the H100.

Monday's preliminary finding from the SAMR comes amidst ongoing trade talks between US and Chinese officials in Madrid, with the tariff truce between the world's two largest economies set to expire in November.

As Sherwood’s Luke Kawa noted in August, China has appeared determined to “wean itself off of any dependence on Nvidia and US technology to develop its AI capabilities.”

According to Reuters, under Chinese antitrust law, companies can “face fines of between 1% and 10% of their annual sales from the previous year.” Nvidia’s sales in China generated $17.1 billion of revenue in its most recent fiscal year. Assuming the maximum penalty, the impact would be ~$1.7 billion, less than 1% of Wall Street’s forecast for Nvidia’s total revenue this fiscal year.

Rocket lab soars to new record close amid rally for retail faves

Rocket Lab ripped by roughly 10% Friday to close at a new all-time high, riding an upturn of retail enthusiasm for a coterie of tech-themed favorites, even as the broader market was more or less flat on the day.

Goldman Sachs’ basket of “retail favorites” — its heaviest weights are Reddit, AppLovin, and Tempus AI — was the second-biggest gainer among the company’s flagship US equity baskets on Friday, rising about 1.6%. The S&P was almost dead flat.

It’s not Rocket Lab’s first retail rodeo, as the money-losing company has more than doubled this year and is up nearly 700% over the last 12 months.
