U.S. stocks down heavily as volatility has its biggest-ever intraday spike

U.S. stocks plunged on Monday. The S&P 500 was down as much as 4.25 percent in early trading, its biggest one-day drop since September 2022, but that proved to be the low point as the benchmark US stock gauge ended down 3 percent. The Nasdaq composite was down 3.43 percent, while the price-weighted Dow Jones Industrial Average lost 2.6 percent, or over 1,000 points.

Two major market trends reversed courses amid a broad global market sell-off: the outperformance of AI-linked stocks and the appreciation of U.S. dollars relative to Japanese yen. The Bank of Japan raised its key interest rate to about 0.25 percent from zero to about 0.1 percent, boosting the value of yen to a seven-month high. 

The VIX index, which tracks the market’s expectations for volatility over the next month, had its biggest intraday rise of all time, up 66.18 percent today. The “fear gauge” hit levels only exceeded by the 2008 financial crisis and the 2020 pandemic.

The S&P sector ETFs were slammed across the board, while tech was the worst-performing with a 3.77 percent retreat. Chip stocks continue to suffer from the downturn as investors questioned the health of the U.S. economy and the sustainability of A.I.-driven gains. The iShares Semiconductor ETF was down 1.76 percent today, while Nvidiawas down 6.36 percent, making it the second-worst performing S&P 500 constituent.

Shares of Apple fell 4.82 percent today after Berkshire Hathaway disclosed that it sold almost half of its Apple shares over the weekend. 

The only good news is Kellanova, whose shares climbed 16.23 percent today. The jump came after reports surfaced over the weekend that Mars, the owner of M&M’s and Snickers, was in late stage talks to buy the maker of Cheez-It and Pringles.

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:

Big Tech capital expenditure soared in 2025. It’s going up another 50% in 2026.

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.”
