The Unsinkable S&P

S&P 500

The Unsinkable S&P

Coming out of the 2022 bear market, the S&P has behaved like it found religion and a fresh pair of lungs. Even this year’s so-called Liberation Day tantrum — which briefly had CNBC anchors fanning themselves — now reads like a speed bump someone painted bright yellow to justify their existence.

How far have stocks run in three years? Far enough to brush up against the record books.

Only the late-stage dot-com fever dreams did better in recent memory — back when analysts were valuing companies by the number of mammals breathing inside the office.

For the moment, stocks appear unsinkable, unslappable, and perhaps uninsurable. But this is what generational technology shifts do: they take a kernel of genuine innovation and inflate a decade of growth into a 36-month highlight reel. We’ve seen this movie. It premiered in 1999 and closed with adults crying into their PalmPilots.

And just as the internet continued reshaping the world long after Pets.com curled up and died, AI will keep marching on whether or not today’s multiples survive a stiff breeze. The technology is real. The valuations, however, will eventually need to stop hyperventilating and sit down with a glass of water.

Sooner or later, the adults have to come back into the room.

P.S. Despite growing concern in the economy today – stubborn inflation, and structural government overspending, sagging employment and consumer confidence – markets are likely to rally into the end of the year. More than the seasonal Santa Claus Rally, traders are going to huff on a Fed rate cut and the prospect of a new accommodating Fed chair. Trump claimed this morning he’s picked his successor to Jerome Powell.

Yesterday, in Grey Swan Live! with Dan Denning we covered a litany of structural challenges facing the economy and markets in 2026 including the end of Quatitative Tightening (QT), the unraveling of the Yen Carry Trade and a stubborn flattening of the M2 “cash curve”.

If you can believe it,  we covered all thaat that ground and more – the role of Dollar 2.0 in financing the national debt, the 2026 outlook for oil and the energy markets and the marginal utility of debt-soaked AI companies – and kept the conversation interesting! Worth a listen if you’ve got a minute. The replay is right here:

Dan Denning: So Much Depends on a Green Wheelbarrow

December 4, 2025 • Addison Wiggin

Wheelbarrows are not chickens. A chicken is a biological production unit. A wheelbarrow is a capital good. A wheelbarrow doesn’t produce work. But it CAN be a productivity multiplier.

And that’s how we have to think of all those GPUs the hyperscalers are spending money on. If their thesis is right, trillion in AI and data center spending now, will translate into a massive burst in productivity and new technologies in the next two decades. That is the only justification for the current valuations/multiples at which these stocks trade now.

The American poet William Carlos Williams wrote, “So much depends, upon a red wheelbarrow, glazed with rainwater, beside the white chickens.”

Today the wheelbarrow is Nvidia Green. And so much of the stock market depends on that wheelbarrow being a big enough productivity multiplier to offset $340 trillion in debt.

Inflation Episodes, Act III: When the Fire Brigade Brings Kerosene

December 4, 2025 • Addison Wiggin

Today, the top 10% of earners account for half of all U.S. consumer spending. Rate cuts that boost stock prices inflate the purchasing power of the wealthy while widening the gulf for everyone else.

How does fattening the brokerage accounts of the top decile fix affordability?

It doesn’t.

But the Fed must cut because the bottom half of America is already showing signs of breaking. If the Fed doesn’t relieve debt pressure, the consumer cracks. If it does relieve it, inflation cracks upward instead.

Credit Markets Price in AI Buildout Risk

December 4, 2025 • Addison Wiggin

Oracle shares managed to pop higher on their AI investment plans over the summer – but quickly gave back those gains as investors digested the total debt the company was taking on.

The AI buildout and its rising costs are raising more questions than answers right now. The CDS market is heating up as a sign of trouble ahead. Keep your eyes peeled!

Dan Denning: The 2026 Battle Royale

December 3, 2025 • Addison Wiggin

Altman’s claim is that not only will people get more done with less with AI, they will be happier because their work is easier and…more fun. This follows a report from Anthropic, responsible for the Claude AI, that said AI increases productivity.

I will say I’m skeptical. But we’ve been told the nature of exponential change is that it comes at you faster than you can measure or observe. And if that is true, it will have consequences in 2026 for employees and investors. Big ones.

For employees–those who are not replaced by automated processes and robots–it will mean secure employment and higher wages. A small number of winners getting richer.
