Strip Out M2, AI Boom Is Sticking to the Bubble Script

Strip Out M2, AI Boom Is Sticking to the Bubble Script

Stocks were hungry for good news from Iran last week. 

Now, traders have moved from hedging geopolitical risk tied to Iran to adding exposure to anything with “AI” attached. 

We’re kicking this week off with renewed concerns that the Strait of Hormuz will remain treacherous for some time. But if you strip out the noise, it reveals what’s really happening in the stock market:

Analyst João Wedson stripped out the rise of M2 money supply to see how far equity prices have run relative to the pool of dollars available in the system.  

Adjusting the S&P 500 Index’s price relative to M2 growth, we’re in the final inning or two of the AI boom on Wall Street.

Stock prices on the S&P 500 have outpaced the growth in money supply. Without inflation, the S&P 500 continues to track the cycle last seen during the telecom buildout in the 1990s.

Of course, “this time is different,” Right?

We heard the same in the late 1990s. It’s a “new paradigm.” The “internet will change everything.” That turned out to be true. It just didn’t happen on the timetable that is convenient for individual investors.

The dot-com crash arrived while the network was still being built. 

Alphabet (GOOGL) and YouTube wouldn’t catch investors’ attention until 2006. Mobile apps that let you skip the line at Starbucks until the 2010s. Netflix (NFLX), PayPal (PYPL), Tesla (TSLA)… today’s stock market darlings were all founded after the dot-com bust. 

AI systems are improving. The demand is rising. Companies are experimenting with deployment. At the same time, the market is assigning value today based on outcomes that may take years to fully materialize.

“Crack up booms” – inflation-driven stock market Melt Ups — add another layer.

Extended periods of 20% annual returns in the stock market have occurred before. They tend to cluster near the later stages of a cycle, when participation broadens and expectations stretch. 

Today’s chart will not tell you when the market will bust. But it should give you serious pause. For an interesting way to trade today’s Ripple Effect, see: Shadow Stocks.

P.S.  Last week on Grey Swan Live!, we showcased our latest research on Shadow Stocks – volatile stocks that move rapidly up and down beneath the surface of the calm indexes. 

Earnings season is a ripe time for cherry-picking stocks. Along with the research, we are launching an upgrade to your Grey Swan forecast emails that will include up to five stock or trade recommendations a week.

To kick it off, we’re going to give you three stocks free of charge. Gratis. On the house. The research is excellent, and the upgraded Grey Swan Pro will be worth your time to consider. Take a look here. 


Copper’s Clear Signal

August 17, 2026 • Addison Wiggin

Copper and resources are sending us a cleaner market signal than AI stocks.

Channeling Ludwig von Mises, we observe this morning that price is not just a number; it’s information. Price reflects what buyers and sellers collectively believe: demand, scarcity, fear, speculation, disappointment, future expectations and available supply.

When prices rise, and inventories fall at the same time, the message is usually straightforward: buyers need the stuff, and there is not enough of it.

Market Crash Insurance Is Cheap

A low VIX does not predict disaster. It measures complacency. A serial skeptic will read it as the calm before a storm. We shook off that feeling this morning and opted to pursue an opportunity instead.

Here goes:

A VIX reading below 15 means the market is not pricing in much near-term trouble, even though there are obvious risks still sitting in the room: Iran, oil prices, memory chip speculation, circular financing, high valuations, epic high concentrations, spiking long-term interest rates, a regime change at the Fed, a meltdown in Japan and a historic deficit and rising national debt.

Beware: Financial Innovation In AI

Money is not flowing in a clean, straight line from outside investors to productive businesses. The firms at the top are investing in and buying from each other.

Microsoft and OpenAI are the easiest examples to follow.

Microsoft says OpenAI has contracted to purchase an additional $250 billion in Azure services, while Microsoft continues to account for $13 billion in funding commitments to OpenAI as an investment.

Signs of a Late-Stage Bull Market

August 12, 2026 • Addison Wiggin

At this stage, it’s a stock picker’s market.

We expect space, robotics and some more visible tech startups to remain sources of speculation. After weakness in the first half of 2026, we’re also due for a strong rotation of capital into natural resources, precious metals, critical minerals and energy.
