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.

‘Golden age of profit margins’ seen in 2026

Wall Street tends to be a pretty optimistic place. But on one measure, market watchers are the most optimistic on record.

FactSet data shows the consensus estimate for S&P 500 net profit margins in calendar year 2026 calls for the gauge to climb to 13.9% in 2026.

But if borne out by events next year “it will mark the highest (annual) net profit margin reported by the index since FactSet began tracking this metric in 2008,” wrote John Butters, senior earnings analyst at the financial data company.

A recent story from Barron’s also commented on the expectations for especially fat profit margins embedded into forecasts for next year.

“We are in the golden age of margins,” RBC’s Capital Markets’ head of US equity strategy, Lori Calvasina, told the magazine.

That’s good news for investors looking forward to next year. But the follow up question, of course, is where the growth in profitability is expected to come from. The answer, as you might have guessed, is tech. Though the precise mechanisms by which those profits land in the coffers of the giant tech firms remains something of a mystery. Barron’s doesn’t get into the details, saying “call it benefits from AI, pricing power, or whatever.”

That doesn’t exactly sound like money in the bank. But even die-hard haters of AI have to acknowledge that betting against the ability of giant tech companies to generate massive profit growth has been a bad trade for the last couple decades.

Opendoor rises after CEO Kaz Nejatian touts an explosion in its home-buying footprint

Opendoor Technologies gained in early trading after CEO Kaz Nejatian touted an explosion in the company’s home-buying footprint.

In a message on X, the former Shopify COO posted two maps: one of which depicts a fairly limited area in which the online real estate company would buy or sell homes, and the second of which suggests that has now expanded to include the entire lower 48:

In a follow-up tweet, Nejatian attributed the gains to AI, writing, “First pic took 10 *years* of work without AI. Second pic took 10 *weeks* of work with AI.”

On his first earnings call as CEO, Nejatian said the company had adopted a “default to AI approach.”

One of his first pledges was to launch Opendoor everywhere in the lower 48.

Hertz surges on bullish options activity

As millions begrudgingly make their way to the rental car counter amid the winter holidays, investors are pouring into calls and sending Hertz stock soaring.

As of 10:51 a.m. eastern, Hertz had seen 17,861 calls traded. That’s already significantly ahead of the 20-day average volume of 12,956. Hertz shares are up more than 12%.

Seemingly juicing the rally was a post on X that read “car rental companies could end up being the picks and shovels of autonomy” that was reposted by billionaire Bill Ackman, whose hedge fund is one of Hertz’s largest shareholders.

If Hertz’s price action holds, the move will mark its ninth-best trading day of 2025.

POET Technologies jumps on elevated call activity

Optical communications company POET Technologies is up double digits in early trading on Monday as this potential supporting player in the AI boom gets a bid from the options market.

Just an hour after the opening bell sounded, call volumes are already running well above their five-session average for a full day.

The stock became a retail favorite in early Q4 right before many speculative trades began to retreat, with record call volumes of nearly 600,000 on October 7. The last big bump in options activity came on December 3, the session after Marvell’s acquisition of Celestial AI, a customer of POET, offered some validation for its technology as a data center solution.
