Chart-o-Rama Depicts Severe Systemic Risk for U.S. Equities

By the Curmudgeon

 

Introduction:

We’ve said it all time and again: there are multiple egregious risks for U.S. equites that have been largely ignored.

As we believe “a picture is worth a thousand words,” we’ve restricting this post to a collection of eye-popping charts which highlight stupendous risk for stocks, especially the highflyers. We’ve included explanatory notes for clarification where needed. So now we will let the charts speak for themselves:


Possible Supply/Demand Imbalance for Equities:

Fed data show that net equity issuance by nonfinancial firms turned positive in Q1, ending a multi-year buyback deficit. That reversal occurred before massive new IPOs BEFORE the $86B SpaceX IPO. Institutional cash is being diverted from buying stocks to absorbing expensive IPOs (with Anthropic and Open AI to come) as well as secondary offerings from Alphabet’s planned $85B offering and others.

Mania in Semiconductor Stocks:

SOX is the ticker symbol for the PHLX Semiconductor Index (formerly the Philadelphia Semiconductor Index). It tracks the performance of the 30 largest semiconductor companies, including chip designers, manufacturers, and equipment suppliers.  Intel’s chart is even more insane with a 500+% gain!


AI Bubble:

It seems inconceivable that private AI companies, like Anthropic and Open AI, have assessed valuation of ~$1 Trillion each. That’s despite the fact they have no earnings and likely won’t be profitable for several years.

Also, the increased earnings forecasts for big tech/AI names are fake.

1.     Hyperscalers’ earnings growth this quarter was boosted by an unusually large contribution from “other income,” which was actually mark-ups of their equity stakes in private Gen AI companies. 

2.     Also, the forecast earnings increases are largely based on circular funding deals, many of which are debt related (e.g. Oracle and Open AI).  Please refer to this IEEE Techblog post for details and discussion:

Merry-go-round of dog chasing his tail: relationship between U.S. hyperscalers and private Gen AI companies

Investech’s Artificial Intelligence Index (AI) is made up of AI-heavy stocks that are representative of investor sentiment -and the potential asset bubble- surrounding the AI phenomenon.

Margin Debt: It’s crucially important to understand that margin works both ways- it propels stocks higher during upswings, but causes mass liquidations (due to margin calls) during selloffs, corrections and bear markets.

 

Graph of Margin Debt through May 2026 release.

U.S. margin debt YoY growth has surged to ~55%, near the highest level since the 2021 peak, according to Topdown Charts analysis. This comes as U.S. margin debt spiked another +$112 billion last month, to a record $1.4 trillion, more than DOUBLING since 2023.

Historically, such rapid surges in margin debt have preceded major bear markets. Margin debt growth peaked in March 2000, just months before the Dot-Com collapse, and in July 2007, 3 months before the S&P 500 topped out ahead of the Financial Crisis. It also peaked in early 2021, just before a sharp market correction later that year. In each of the prior three instances, the market took several months to actually top out after this signal first flashed, but the warning itself has historically proven reliable.

U.S. Household Ownership of Stock at All-Time High:

Where is the buying power going to come from with the public maxed out on stocks as a percent of their total financial assets?

U.S. Equity Valuations:

We’ve highlighted sky high valuations for years, but it seems there’s no upper bound?  The U.S. stock market has reached an all-time high across multiple valuation metrics, P/E, forward P/E, Shiller P/E, price-to-book, price-to-sales, EV/EBITDA, Q ratio, and return on equity, surpassing peaks from 1929 and the 2000 dot-com bubble. The composite valuation percentile now sits at the highest level in recorded history. Extreme valuations at this level have historically preceded extended periods of equity underperformance, signaling elevated risk and potential mean-reversion pressure ahead.

Equity Risk Premium and Excess CAPE Yield:

1.  Observe the narrow gap between the S&P 500’s earnings yield—the inverse of its P/E ratio, expressed as a percentage—and the yield on 10-year U.S. Treasury Note. We noted in the previously referenced Curmudgeon post that this equity risk premium is way below its long-term norm of roughly 5%, leaving equities appearing very expensive both on an absolute basis and relative to fixed income. 

The trailing 52-week P/E ratio of the S&P 500 is ~25.11 so the reciprocal earnings yield is ~3.98% while the U.S. 10-year yield is now ~ 4.5%. That translates into a negative equity risk premium of -0.58%.

2. Cyclically Adjusted Price-to-Earnings (CAPE) is calculated based on the average of 10 years of inflation-adjusted earnings.

The so-called Excess CAPE Yield—a measure of that gap that accounts for inflation—is at around 1.3%, near its lowest level of the past decade.


JP Morgan’s models say that “equities look rather expensive--on an outright basis relative to the norms of the past 30 years.”  And “equities currently look even more expensive relative to bonds,” according to the investment bank. Here’s yet another chart to confirm that statement:

From Investech Research:

Housing Starts fell -15.4% in the latest reading (May 2026) following an -8.5% decline in April 2026.  After remaining in a relatively narrow range for the last few years, this release signals a major break to a new 6-year low.

Housing Starts are an important measure of housing market health, as they indicate the future supply of homes that will be available to buyers. In addition, a decrease of this magnitude signals a likely decline in construction and manufacturing jobs and a further slowdown in housing activity across the board.

 


The housing market has been largely stagnant for the last few years and this recent drop in Housing Starts warns that the sector could be heading for further trouble.

We conclude with a chart from Tom McClellan on X: 

“A pattern of 15 good stock market years (white portion of the box) followed by 15 years when you had better be a market timer (yellow portion) has worked all the way back to the 1830s.  The next yellow box starts about now.”
