Wall Street’s Bubble Mechanics

Wall Street’s Bubble Mechanics

We’re hyper aware this morning that Wall Street is in the throes of an AI bubble.

The numbers are startling: the Shiller CAPE ratio has climbed above 34, its highest level since the dot-com mania, while margin debt among retail investors is pushing toward records last seen in late 2021.

According to Bloomberg, the top 10 stocks now make up over 41% of the S&P 500 — a concentration “unprecedented in modern market history.”

Even cautious voices are sounding the alarm. “This is a very precarious setup,” warns Rob Arnott of Research Affiliates. “When so much of the market’s value is tied up in a handful of names, history suggests it doesn’t end well.”

The Magnificent 7 alone accounts for 35% of the S&P’s weighting, making the index look less like a diversified basket of U.S. enterprises and more like a leveraged bet on Nvidia, Apple, and Microsoft.

💾 AI Mania and the Fed’s Push

The Fed’s pivot into rate cuts is adding fuel.

Last Wednesday’s quarter-point trim was presented as a “risk management cut,” but in practice, it kicks $10 trillion parked in money market funds into more speculative channels.

Much of that capital is eyeing AI as the engine of the “new economy reset.” CoreWeave, Intel, and Nvidia dominate headlines not just for technology breakthroughs, but because the speculative capital needs a home.

As one strategist told Financial Times, “AI has become the vessel into which liquidity is being poured. Whether it can carry the weight is another question entirely.”

🥇 Gold Goes Mainstream

Against this froth, gold is gaining legitimacy as a mainstream portfolio asset. JPMorgan has quietly shifted away from the old 60/40 orthodoxy, publishing forecasts that see gold rising to $4,000 an ounce by mid-2026 — and perhaps $6,000 by the decade’s end.

The bank cites a weaker dollar, persistent geopolitical risk, and central bank diversification as tailwinds.

“Gold has moved from a tactical hedge to a strategic allocation,” JPMorgan’s private bank wrote this summer. That sentiment is showing up in flows. Bullion deliveries, ETF inflows, and even central bank purchases are running at their strongest pace in decades.

Meanwhile, the junior miners — often the last leg of a metals bull market — are stirring.

The Wall Street Journal reported last week that Canadian and Australian explorers have seen double-digit gains since July, even as their larger peers plateau.

Silver, too, has surged past $44, with traders whispering about a retest of its $48 high.

🌍 Politics at the Edge

Geopolitics only complicates the picture. President Trump meets Argentina’s Javier Milei this week, hoping to calm markets ahead of $9.5 billion in looming debt payments.

The peso has been in freefall, and Milei’s radical libertarian program now faces its first true market test.

At the UN in New York, Canada, the UK, and Australia recognized a Palestinian state, joining 147 member nations already on record.

U.S. officials criticized the move, and Israeli Prime Minister Benjamin Netanyahu dismissed it outright: “It’s not going to happen.” Still, the coordinated step signals a broadening break between Washington and its traditional allies.

🧭 Reading the Signals

So, the ever-present question: what to do with your money?

Acknowledge the bubble, but don’t get trapped in it.

Speculative froth can run longer than logic allows, but concentration risk is real.

“We may take a breather here in the next few days given how overextended the market is in the short term,” notes Portfolio Director Andrew Packer, who just made a trade betting on a market pullback over the next few weeks in the Grey Swan Trading Fraternity.

Andrew adds, “I don’t think we’ve seen the final top for markets yet – but it’s now or never for a pause before a year-end rally.”

Diversify where incentives still make sense — commodities, select value plays, and yes, even gold.

Gold’s “gradual rise,” as JPMorgan frames it, is your friend if you’re reallocating at this moment. But don’t treat it as a slam dunk. Remember: after 1980, gold holders waited 25 years to recover in real terms.

Balance, ballast, and patience remain the investor’s best tools.

P.S.:  Don’t miss this Thursday’s Grey Swan Live! at 2 p.m. ET. Andrew will be joined by Shad Marquitz to dig into commodities. With gold over $3,700, silver breaking out, copper near all-time highs, and uranium stirring, the question isn’t whether to own them, but how.

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.

The Inflation Episodes — Act II, Featuring Silver, Gold and Dollar 2.0

December 3, 2025 • Addison Wiggin

American consumers don’t feel – or are at least unaware of – monetary nuance. They’re just getting the bill.

Trump declared last night that “affordability doesn’t mean anything to anybody,” dismissing the term as a “Democrat scam”— this despite recently proclaiming
himself the “Affordability President” on Truth Social.

That’s the current state of political messaging on cost-of-living: part whiplash, part vaudeville. But voters aren’t confused. Grocery prices are still 30% higher than 2020. Tariffs add daily friction. Utilities, rent, houses, tuition, healthcare continue their daily grind upward.

The “New” Contrarian Case for Bonds

December 3, 2025 • Addison Wiggin

During a Fed rate cut cycle, bond yields follow, which typically means bond prices tick higher. If you buy bonds now, you’ll be getting in ahead of the crowd.

And if this tech wreck shapes up anything like 2000-01, investors will want to get out fast. Despite the debt mess in Washington, bonds will again look “safe.”

One minor bonus: if you buy now, you’ll lock in higher yields before the next Fed rate cut, which is expected to come one week from today.

American Life: Less Ordinary

December 2, 2025 • Bill Bonner

But Green is describing more than just a new calculation. He’s talking about a new form of misery.’ It’s a poverty where you may still have most of the accoutrements of middle-class life. But your relationship with the financial elite has changed: you are indentured to the credit industry — for life.
