The Open

Today in one paragraph

Alphabet's stock fell 12.6%, its worst day since Google went public in 2004, after the company spent more cash than it made last quarter. ADT agreed to be bought by Thrive Holdings for $10 a share in cash and jumped 33.2%. Marvell fell 13.2% on a report that it is in talks to buy the laser maker Lumentum. The economy grew at a 3.4% annual rate in the third quarter, faster than expected, while the Fed's preferred inflation gauge rose to 3.6% from a year earlier. The Nasdaq fell 1.4% and the S&P 500 0.3%, but smaller companies rose: the Russell 2000 gained 1.0%. After the bell, Amazon fell about 6% and Intel about 16%. Our read: money is walking out of the AI giants that spend more than they earn and into the rest of an economy that is still growing.

What Happened Today?

The most important stories, through our eyes

ADT agrees to a $10-a-share sale

The home-alarm company agrees to a $15.3 billion takeover by Thrive Holdings, and its stock jumps 33.2%.

ADT ADT $9.87 +33.2%
What the market heard
ADT began in 1874 as American District Telegraph and grew into the biggest name in American home alarms. Apollo bought it in 2016 and listed it again in 2018. In August 2020 Google bought a 6.6% stake for $450 million, and the stock rose 56.6% in a day, its best since the listing. State Farm invested in 2022. Even so, it closed between $6 and $9 on every trading day this year until Thursday. It made our "Big Moves, but No Explanation" list on Wednesday, when it rose 7.9% with no news.

On Thursday the news came. ADT agreed to be bought by Thrive Holdings, which calls itself "a permanent capital holding company focused on investing in established businesses," for $10 a share in cash. That is about $7.6 billion for the stock and $15.3 billion for the whole company, debt included. The price is 45.6% above Tuesday's close of $6.87, which the companies call the "unaffected" price, before Wednesday's jump. Funds managed by affiliates of Apollo, ADT's former owner, are providing all of the financing, and the deal has no financing condition. For 30 days, until Nov. 28, ADT may look for a better offer. The deal needs shareholder and antitrust approval and should close in the first quarter of 2027. The stock rose 33.2% to $9.87, its second-best day since the 2018 listing, on about 22 times its usual volume. It sits 1.3% below the offer.
What it might mean
A 1.3% gap up to five months from closing says the market treats this as done and expects no bidding war. That makes sense: when the money comes from the company's former owner, which knows the books better than any rival bidder, the 30-day shop for a better offer is mostly a formality. Our call: no higher bid by Nov. 28, and the stock stays within 3% of $10 until the deal closes.
What would kill it
A rival bid before the shopping period ends on Nov. 28, or the stock closing below $9.50, which would say investors doubt the deal will close.

Marvell falls 13% on Lumentum deal talks

The data-center chip designer is in talks to buy the laser maker Lumentum, Bloomberg reported, and its own stock takes the hit.

Marvell MRVL $218.34 −13.2%Lumentum LITE $919.53 +0.6%
What the market heard
Marvell was founded in 1995 by Sehat Sutardja, his wife Weili Dai and his brother Pantas Sutardja. Today it designs custom AI chips for the cloud giants and the chips that push data down the fiber-optic links inside data centers. Lumentum, spun off from JDS Uniphase in 2015, makes the lasers that turn those signals into light, and lately optical switches that route light without converting it back to electricity. In its last forecast, in August, Lumentum expected $1.225 billion to $1.275 billion of revenue for the quarter that ended in September, and said its optical switches and cloud modules were "beginning to layer in." Investors have noticed: Lumentum's stock is up 329% in a year, Marvell's 143%.

On Thursday Bloomberg News reported, citing people familiar with the matter, that Marvell is in talks to buy Lumentum and that a deal could be announced as soon as next week, CNBC reported. Marvell fell 13.2% to $218.34 on twice its usual volume, which took more than $30 billion off its market value. Lumentum, the company Marvell would buy, rose just 0.6%. Lumentum reports its results after the close on Nov. 5.
What it might mean
When the buyer falls 13% and the target barely moves, the market is voting on the price, not the idea. Owning both the chip and the laser in an AI data-center link makes sense on a whiteboard. But Lumentum has more than quadrupled in a year, so Marvell would be paying top dollar for the hottest corner of the AI supply chain, quite possibly with its own stock. Lumentum's flat day says traders don't expect a big premium either. Our call: if a deal is signed, the premium over Lumentum's last price before the announcement is under 20%.
What would kill it
A signed deal at a premium above 30%, or Marvell's stock getting back above Wednesday's $251.65 close before any announcement.
Marvell, the past year

Big Moves, but No Explanation

Money moves in mysterious ways.

Lowe's LOW +4.5%

What it is. The second-biggest American home-improvement chain after Home Depot. It began as a hardware store in North Wilkesboro, North Carolina, in 1921.

What we know. No filing or release on Thursday, and it doesn't report until Nov. 18. The whole home group rose: Home Depot 3.6%, Masco 5.4%, which reported on Wednesday, and Builders FirstSource 12.8% after reporting on Thursday. The 10-year yield, which steers mortgage rates, fell. Lowe's is up 13% in a month but still 27% below its high of the past year.

Today vs. other home-improvement stocks

Our guess: a bet on the house. Lower yields and two strong reports from suppliers sent money into anything tied to fixing up homes, and Lowe's, further below its high than Home Depot, caught more of it.

General Dynamics GD +4.6%

What it is. The maker of Gulfstream business jets, Abrams tanks and, through Electric Boat, the Navy's nuclear submarines.

What we know. No filing on Thursday; it reports on Friday. Its rival in Navy shipbuilding, Huntington Ingalls, jumped 13.2% and L3Harris 6.8%, both reporting on Thursday. General Dynamics is up 12% in a month and 6% below its high of the past year.

Today vs. other defense stocks

Our guess: buying the report before it lands. When the other shipbuilder posts a blowout, investors assume the Navy's money is flowing to both yards.

NXP Semiconductors NXPI +5.7%

What it is. A Dutch chipmaker, spun out of Philips in 2006, that sells chips for cars, factories and payment cards. Qualcomm agreed to buy it in 2016 and walked away in 2018 when China's regulators never approved the deal.

What we know. No filing on Thursday; it reported its quarter on Tuesday. Other chipmakers for cars and factories rose far less: STMicro 3.0%, Microchip 1.9%, Analog Devices 1.2%, Texas Instruments 1.0%, while ON Semiconductor slipped 0.5%. NXP is up 12% in a month and 19% below its high of the past year.

Today vs. other chipmakers for cars and factories

Our guess: the rotation's favorite chip. On a day money left AI's high flyers for the real economy, a chipmaker for cars and factories, still well below its high, was an easy place to land.

The Earnings Desk

Results, briefly

Alphabet GOOGL −12.6%, its worst day since Google went public in 2004, which CNBC estimated wiped out roughly $500 billion of market value. Its third-quarter report showed revenue up 25% to $127.6 billion, but capital spending of $51.4 billion left free cash flow at negative $9.1 billion, and search revenue of $63.35 billion missed the $64.96 billion analysts expected. It kept its forecast of $195 billion to $205 billion of capital spending for the year. Its business chief said search was hurt partly by lower ad sales inside its AI Mode. Wall Street forgave the AI bill as long as search paid it. On Thursday search came up short, and the bill was still there.

The companies that rent out AI computing power fell with it: IREN 9.0%, Nebius 5.7%, CoreWeave 5.0% and Oracle 3.4%. Microsoft's finance chief said delays at outside providers of GPU computing will push some capacity into the first half of 2027, and both Microsoft and Alphabet came in under analysts' capital spending estimates, CNBC reported. For two years the neoclouds sold one story: the giants can't build fast enough. Thursday they heard the giants say "not so fast."

Software had a brutal day too. ServiceNow NOW −26.9%, its worst day in at least ten years, after forecasting slower growth in contracted future revenue. Fortinet FTNT −20.1%, even after raising its revenue forecast; its gross margin of 79.6% missed the 80.1% expected, CNBC reported.

Connecting the Dots

Where we are, and where the puck goes next

The economy is fine. The AI giants are the ones being audited.

On Thursday the government said the economy is growing fast. The market answered by selling the companies that have done the most to make it grow.

The numbers first. The economy grew at a 3.4% annual rate in the third quarter, ahead of the 3.1% expected. Private investment jumped 19.4%, led by a 20.9% surge in equipment spending, and CNBC credited the AI build-out for much of the growth. Weekly jobless claims fell to 194,000. But inflation by the Fed's preferred gauge rose to 3.6% from a year earlier, as gasoline and other energy goods jumped 9.2% in September alone. Futures put the odds of a December rate hike above 77%, according to CME FedWatch data cited by CNBC.

Now the market. Alphabet had its worst day ever, the AI landlords fell with it, and Amazon and Intel slid after the bell. Meanwhile the Russell 2000 of smaller companies rose 1.0%, and home-improvement, defense and cruise stocks rallied. This isn't fear. The VIX barely moved and the S&P 500 lost just 0.3%. It is a rotation: the same investors who paid any price for AI growth are now asking who pays for the build-out, and the answer this week was "the shareholders." Alphabet and Amazon both kept their spending plans and both showed negative free cash flow. Microsoft, the one that trimmed its plan and kept its cash flow positive, held up.

Why now? Because money costs 5%. A company burning cash at a 5% 10-year yield is a different investment from one doing it at 3%. The surprise is that on a day of strong growth and hot inflation, the 10-year yield fell, to 4.99%. Part of that was oil, which slipped on reports of renewed U.S.-Iran peace efforts. Part, we suspect, was money leaving tech for the safety of bonds. If yields keep falling while growth holds, the rotation into the rest of the economy has fuel. If the Fed hikes in December anyway, nobody gets a free pass, the AI giants least of all.

Where the puck goes next: our odds through November

The rotation keeps going45%

Investors keep moving from AI spenders to the rest of the market. Small companies, industrials and consumer names beat the Nasdaq, and the S&P 500 holds roughly flat because its biggest members drag. Winners: small caps, housing, defense, AI suppliers that get paid in cash. Losers: cash-burning AI giants and the neoclouds.

You'll know it's this one if the Russell 2000 beats the Nasdaq over November.

AI wins back the crowd30%

Nvidia's mid-November report shows demand still outrunning supply, the capital-spending worries fade, and the giants bounce. Winners: chips, the hyperscalers, the neoclouds. Losers: the defensive names that led this week.

The tell: Alphabet closing back above $324.89, its price before Thursday's drop, by Nov. 30.

Everything gets marked down25%

Hot inflation and a hawkish Fed, or strikes on Iran after the midterms, push yields back above 5% and oil higher. The rotation stalls because nothing looks cheap at those rates. Winners: oil producers, the dollar, short-term Treasuries. Losers: small caps first, then everything priced on distant profits.

The tell: the Russell 2000 closing more than 5% below Thursday's 2,859.22.

What would make us tear this up: Amazon recovering its after-hours loss by next Friday while the Nasdaq beats the Russell 2000 over the same week. That would mean investors still pay for AI spending whatever the cash flow, and the rotation was a one-day story. We'll keep score at the end of November.

Tomorrow Exxon and Chevron report before the bell, and Friday is the last trading day of October: our first Closing the Books, the month audited, and the first Call from our paper portfolio.
