S&P 500 snaps losing streak as Tesla goes parabolic

The S&P 500 climbed 0.2%, the first time it rose this week. The Nasdaq 100 outperformed and gained 0.8%, while the Russell 2000 was up 0.2%.

Tesla’s 21.9% day led Magnificent 7 stocks and pushed the S&P consumer-discretionary sector ETF higher by 3.2%. It was the stock’s third-best daily gain on record. 

Among other sectors, materials select fell 1.2% and was dragged down by earnings miss at Newmont Corp . Shares slid 14.7% and the stock became the biggest S&P 500 laggard of the day.

The market did not have a strong reaction to any of Thursday’s economic data. New-home sales crept higher, likely due to lower mortgage rates during September. Initial jobless claims filed last week fell. 

Treasury yields fell modestly for the first time this week. Oil futures settled lower. The dollar weakened.

More on single names: UPS surged 5.3% on the day after the company returned to profit for the first time since the end of 2022. An economic barometer, the shipping company’s solid performance may be a testament to consumer resilience. Molina Healthcare was the second-best-performing S&P constituent on the day, rising 17.7%. Whirlpool Corp. climbed 11.2%, and executives expected demand to pick up after the election. 

Conversely, Southwest Airlines slid 5.6% after the airline said it reached a deal with activist investor Elliott Investment Management to keep its CEO. IBM dropped 6.2%, as sales figures failed to impress Wall Street.

Trump’s “impossible trinity” on AI and energy


Everyone loves a good trilemma.

In economics, the most famous of the genre was developed by Fleming and Mundell, which posits that you can only successfully achieve two of the following three objectives: the free flow of capital, a fixed exchange rate, and independent sovereign monetary policy.

George Pollack, senior US policy analyst at Signum Global Advisors, proposed a trilemma of his own to describe the Trump administration’s competing policy aims as a red-hot AI boom devours power and leaves households miffed by rising electricity bills.

He wrote:

This note flags what we believe to be a simple reality whose salience will continue growing in US politics in coming months: the Trump administration, in its remaining three years will face a trilemma as the nation waits for its energy bet to play out – proving able to achieve two, but not all three, of the following objectives:

-Fulfill AI’s energy-appetite.
-Keep repressing renewable sources of energy.
-Appease American electricity consumers.

Trump AI trilemma

As for evidence that the Trump administration is taking a fossil fuels first approach while stunting renewables, Pollack pointed to the One Big Beautiful Act, which shrinks access to tax credits for green energy, as well as the end to the federal pause on LNG export permits. However, it would be “inaccurate and unfair” to blame Trump’s policies for surging electricity prices in recent months, he added.

While the government has pursued the expansion of nuclear power as a way to solve this trilemma, the long lead times involved are incongruent with a short-term fix.

Palantir reports Q3 earnings results

Palantir climbs toward a fresh record high ahead of earnings report

Traders and Wall Street are waiting to see whether Palantir’s latest numbers after market close today will continue to beat expectations.

Joby’s UAE reported certification delay stokes fears that air taxis may be further off than thought, sending eVTOL stocks down

Commercial air taxi service may be on a slower path than investors previously thought.

Shares of Joby Aviation fell more than 9% on Monday morning amid a report from The National that the company’s UAE certification will be completed by the third quarter of next year. That’s a significant delay from Joby’s own projected timeline in February, when it said it planned to carry passengers in Dubai in “late 2025 or early 2026.”

Rival Archer Aviation, which also recently suffered a hit to its UAE certification timeline, fell more than 9%. Joby and Archer each are expected to report their earnings results later this week.

Also potentially causing some investor pullback is the planned IPO of Beta Technologies on Tuesday. Beta, a manufacturer of electric aircraft, received a $300 million investment from GE Aerospace in September.

Micron jumps on report of surging memory chip prices

Micron, the US memory chip specialist, is up more than 4% in early trading Monday after a report that Samsung Electronics was temporarily pausing new pricing on contracts for the latest version of ubiquitous short-term computer memory: Dynamic Random Access Memory, or DRAM. The chip giant wants to see where the market settles after a recent spike in spot prices for memory chips driven by the AI boom.

DRAM and memory chips of all sorts have pricing power because of how much demand is outpacing supply. Last week, South Korean memory chip behemoth SK Hynix said it had already “sold out” all of its 2026 production.

Such signs of ongoing AI-related demand for IT hardware also gave a lift to other data storage device makers, such as Seagate Technology Holdings and Western Digital. The duopoly dominate the hard disk drive market, and have ridden a boom in demand for the affordable data storage devices to gains of more than 200% in 2025.
