US stocks gain for three weeks straight despite modest loss on Friday

The S&P 500 fell 0.1% on Friday after swinging between small gains and losses but still ended the week with 0.6% gain. The Nasdaq 100, similarly, closed down 0.5% but up 1.1% for the week. On the other hand, the Russell 2000 added 0.7% on Friday but had a weekly loss of 0.1%.

The personal consumption expenditures price index for August came in 2.2%, the lowest since February 2021. This was closer to the Federal Reserve’s inflation target of 2% than last month. Core PCE — excluding energy and food — picked up slightly from last month to 2.7%.

Treasury yields fell. The dollar retreated for the fourth consecutive week.

Most S&P 500 sectors advanced. The energy sector took the lead, up 2%. On the other hand, technology, materials and health care declined. The technology select sector SPDR fund slid 0.9%.

Tech stocks were dragged by Dell, which lost 4.9%, and HP, which fell 4% on news that Bank of America Securities downgraded the stock from Buy to Neutral. Shares of Nvidia also dipped, down 2.2% on Friday, after Bloomberg reported that China urged local companies to buy domestically produced chips instead of the Nvidia ones. 

Casino stocks continued their rally on the heels of Beijing’s stimulus. Wynn Resorts and Las Vegas Sands were among the best S&P 500 performers of the day, and both added more than 20% this week.

FDA says it will take “decisive steps” against GLP-1 compounders, HHS refers Hims to DOJ for investigation

The Food and Drug Administration said it would take "decisive steps" to restrict GLP-1 compounding, a day after Hims & Hers announced that it would sell copies ofNovo Nordisk’sWegovy pill.

The FDA specifically called out Hims in the announcement. Additionally, Department of Health and Human Services' General Counsel Mike Stuart said in a post on X on Friday he has referred Hims to the Department of Justice "for investigation for potential violations by Hims of the Federal Food, Drug, and Cosmetic Act and applicable Title 18 provisions."

In a statement, Hims said the company "has always operated with a deep commitment to the safety and best interests of consumers and in compliance with applicable law."

"We have a long history of successfully working with regulators, and look forward to continuing to engage with the FDA to ensure safe access to affordable healthcare," they said.

This marks a significant shift in tone from the FDA, which has done little to prevent companies like Hims from marketing copies of Novo's lucrative weight loss drugs.

Shares of Hims fell 14% after hours. The stock had already taken a hit after FDA Commissioner Marty Makary said in an X post on Thursday that the agency would “take swift action against companies mass-marketing illegal copycat drugs.”

Airlines rise, continuing their volatile 2026, as US-Iran talks may foreshadow some oil supply relief

Airline stocks are surging on Friday, as the market appears to be pricing in some medium-term oil pricing relief following talks between the US and Iran. Iranian officials referred to the meeting as “a good beginning.”

Shares of budget carriers, which have tighter margins and are more sensitive to fluctuations in fuel costs, are leading the surge. Frontier Airlines and Allegiant up more than 13%, while major airlines like United Airlines, American Airlines, and Delta Air Lines are also up at least 6%. JetBlue and Alaska Air are similarly up about 6%.

The market more broadly is rebounding on Friday, with the S&P 500 up 1.6% and bitcoin recovering some of this week’s losses.

Airlines have been volatile to start 2026 amid geopolitical tensions, varying annual forecasts, and the impact of winter storms.

The AI supply chain is soaring thanks to Amazon’s capex budget

If tech companies are going to spend way more than expected on capex, well, that means other companies are poised to benefit from that massive spending spree.

Amazon’s plan for $200 billion in business investment this year was the exclamation point to end a reporting period that saw every Magnificent 7 hyperscaler that provides guidance offer a 2026 capex budget well above what Wall Street had anticipated.

Here’s a look at the different parts of the supply chain that are soaring on the persistent demand for, and seeming scarcity of, AI compute:

For memory chips, the “parabolic price hike” is continuing to ramp higher

The remarkable run-up in prices for memory chips continued into early February, analysts at Bernstein Research say, driven largely by data center demand from hyperscalers and cloud service providers (CSP).

Prices for NAND flash memory wafers — a type of memory used in devices, as it retains data even when powered down — soared 35% between the end of 2025 and February 2.

Spot prices for DRAM — ubiquitous short-term data storage chips — jumped about 28% in that period. But that massively understates the remarkable shift in pricing for what were long seen as commodity tech hardware inputs. DRAM prices are more than 2,000% over the last year, while NAND prices are up more than 600% in that period.

The ongoing momentum provides still more support for memory chip plays like Micron and Sandisk, which have been big market winners in recent months.

In a note published earlier this week, Bernstein Research analysts wrote:

“The parabolic price hike continued in Jan. Indicated price increase for 1QCY26 is much stronger than we expected and we hence see upside to our near term memory pricing projection. Unrelenting CSP demand remained the main driver. PC and Mobile demand hasn’t been destroyed yet because of lean inventory & pull-forward purchase. Going forward price hike is expected to continue but likely at a slower rate, as PC and Mobile demand should contract meaningfully this year. Price however may stay elevated throughout this year, supported by CSP demand.”
