A Market In Search of The Greatest Fool

A Market In Search of The Greatest Fool

Q: What happens when you close down most public spaces, give everyone $1,200, and only leave the stock market open?

A: You turn Wall Street into a giant casino.

One of the fascinating cross-currents of the pandemic era was seeing that experiment play out in real time.

For millions who could work remotely, the extra $1,200 was like getting capital to buy lottery tickets.

That money went into stocks like GameStop, as well as many SPAC firms – shell companies looking to take small, high-growth opportunities public.

By the time the mania peaked in late 2021, margin debt was at an all-time high as institutional money raced to catch up with retail investors.

But new all-time high margin debt is back today:

Turn Your Images On

Margin debt is now back above its 2021 peak

We had a bear market in 2022, as rising interest rates sucked marginal capital out of the market.

Along the way, we saw that many investment opportunities of the time were simply one buyer getting in ahead of the next buyer…. in search of the “greatest fool” who bought last.

P.S. Given the resurgence in “meme stocks” the past few weeks – Opendoor, Kohl’s – it may be a sign of market froth. And it may take a 5-10% pullback to get some sanity back in the markets.

If you’re leveraged in this market. Don’t be. You’re in a crowded trade. When a trade is crowded, getting to the exit first is on everyone’s mind. Panic now and avoid the rush.

Autonomous Weapons

October 29, 2025 • John Robb

In the past, weapon systems took decades to build and changed slowly. Autonomy changes this. For example, new capabilities developed by field tests or simulation (testing scenarios in full physics simulators depicting actual environments) could be downloaded to existing weapon systems, making it possible to upgrade a weapon system significantly without any meaningful hardware changes. A process of improvement that used to take many years would shrink to weeks and, in time, days.

The Great Repricing of Power

October 29, 2025 • Addison Wiggin

Markets heard what they wanted. NVIDIA’s stock surged premarket on news that Trump would discuss the company’s Blackwell AI chip with Xi, pushing it to an unprecedented $5 trillion valuation.

Meanwhile, China quietly bought its first cargoes of U.S. soybeans this season — a symbolic gesture that reminded traders that diplomacy still runs on trade.

“It’s not détente,” wrote  Bloomberg’s Jennifer Welch this morning, “It is a dealmaking with a timer.” Wall Street is ambivalent on peace, but they do like profits.

In the background, China’s biotech sector continues its ethically murky sprint forward — this week, reports surfaced of Chinese scientists creating monkeys engineered to exhibit schizophrenia and autism.

About Yesterday’s Rally

October 29, 2025 • Addison Wiggin

A high concentration of capital in a few stocks at the top ranks high among the features we detailed in Anatomy of a Stock Market Bubble.  

On days like yesterday, headlines urge investors to buy. However, they also underscore the fragility of this terrifying bull market: just a handful of names can make the difference between a big up day and a big down day.

American Autonomy

October 28, 2025 • John Robb

America’s role in the world isn’t that of the world’s policeman (a temporary post-World War II role foisted upon the U.S. due to the Cold War) or as the destination of immigrants (for most of the 20th century, when we saw the most significant increases in individual incomes and quality of life, the U.S. didn’t accept many immigrants). Instead, the role the U.S. has played throughout its existence is as the world’s leader in the production, adoption, and socioeconomic integration of new technologies. We figured out how to do it successfully first, and the world followed.
