Stocks Can’t Get Much More Expensive Than This

With stocks within sight of new all-time highs, a danger we noted in the spring is back—markets are historically overvalued once again.

One measure of looking at the stock market is comparing its current valuation metrics to its historical average.

On an earnings basis, markets are now back to two times standard deviations over their average:

Only 5% of the time, the stock market is more expensive than it is now.

With corporate earnings yet to reflect the impact of tariffs – and with many of those tariffs likely to come inching back in July – it may be time to take some profits off the table following the stock market’s stellar rebound.

This doesn’t mean the market can crater immediately overnight in another Liberation Day move, but it does mean easy money has been made, and it’s time to start packing up.

Panic now, 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.
