Five Signs of a Market Bubble Investors Are Tracking

Stretched valuations and a surge in speculative trades are raising red flags, even as growth persists

By Hannah Erin Lang, The Wall Street Journal, July 27, 2025

  • Speculative stocks like Opendoor and Kohl’s are surging, reminiscent of 2021’s meme stock frenzy.

  • Crypto prices are rising, fueled by Trump administration policies and companies adding bitcoin to their balance sheets.

  • Market breadth is improving and the economy remains strong, but stock valuations are stretched and the job market shows signs of weakening.

Some investors say the action is the latest phase in what has turned into a near-euphoric rebound from April’s tariff turmoil. Since the market tumbled and then turned higher, there has been a stampede into risky assets such as meme stocks, cryptocurrencies and shares of smaller companies that have yet to turn a profit.

To some, this resembles a bubble—a period of frenzied market activity and speculation that artificially inflates asset values, driving prices to an eventual breaking point…

Speculative stocks are having a moment

Crypto prices are surging

Breadth has improved… Analysts typically consider that kind of improving breadth a sign of a sustainable bull market. ..

Yet stock valuations are stretched. The equity risk premium, defined as the gap between the S&P 500’s projected earnings yield and the yield on 10-year Treasurys, is close to zero. That means that the extra return for owning stocks over lower-risk bonds has nearly vanished, which investors consider an unhealthy sign…

Private-sector job growth has fallen to the lowest level in eight months. Hiring has slowed to a trickle, and college graduates are struggling to land roles.… [end quote]

Bubbles end when euphoria dries up and the next buyer simply doesn’t arrive.

Based on what?

The reason why I ask is that such is a largely a made up number based on what the researcher thinks projected earnings are.

I just looked up two different sources and Wells Fargo has a negative ERP:

And WisdomTree has it as positive but below the median (page 19 of 32):

Who to believe, and does it really matter since it is largely based on a guess about future earnings (especially when such guesses are often below actual results).

Well it would always be best to use the higher projection to get a look of the “possible”. Still shows a period of low returns because of yield.

You can also do this with TBills and the trailing earnings of the S&P for a different look.

@Jkenn21 can you link to a chart that shows this and is continually updated? If so, I will add it to the Control Panel.

Sheesh there are horrible disconnects in that chart as yields rise.

Very well put together chart.

There will always be money on the sidelines. Money changes hands for assets. While a decline in the asset can make it worth less money that does not reduce the money on the side lines.

Point being money on the side lines makes higher valuations higher. Until it does not.

The market can stay irrational for a while. The current policies in tariffs and corporate taxes are destroying the American economy going forward.

The Magnificent 7’s share of S&P market cap seems very frothy, if not bubbly.

AI is driving a lot of the craziness, with lots of cheddar being thrown around to attract talent.

All signs point to… :bubbles:

At the same time, their combined earnings (north of $150 billion) make up more than half of the total earnings of the S&P 500. In addition, their earnings growth rate is more than twice that of the rest of the index.

Yesterday Microsoft said it has trouble keeping up with demand for Azure, its cloud computing platform, and Nvidia has said its growth is constrained by the supply of chips. Perhaps the high share of the S&P market cap is justified.

Perhaps. Don’t get me wrong, I’m not suggesting short-term apocalypse, just questioning the commonly held belief that the Magnificent 7 will soar to infinity.

There is also something to be said about not having all of your eggs in one magnificent basket.

The AI driven frenzy could all slow way down with regulatory reforms or an industry disruptor…enter open-source Thinking Machines Lab AI.

You may or not think that a recession is in the very near future, but there’s certainly one in the future. With many of the Magnificent 7 companies depending on advertising revenue, they’ll take a big hit. Advertising spending is the first to get slashed during economic downturns.

Second to Lastly - Lots of dorks are flocking to tech, just for the flock of it! Take recent IPO launches of Figma, Circle, and CoreWeave as examples.

Lastly - lots of money is flying into large cap tech, this typically leads to overvaluation.

Deregulation seems to be the trend with this administration.

I think kleptocracy is a better description of what we seeing now.

Given that we live in a global economy, any regulation from outside the US could also be disruptive.

Kleptocracy + Plutocracy + Kakistocracy = Kleptoplutokakistocracy!

Seems like a Dutch or German word…

Very much like a German compound word. I’m going to borrow that. : )

That’s pretty foolish turn down the 1 billion. Ai is ai. Ethical? More like impotent. There’s no killer app.

Going the way of pet.com or ftx at the tops of markets.

The dot con mba sold out for a pay day if smart.

Google is stunting it’s own potential w ai results.

When you have money, money isn’t everything. Thinking Machines just wrapped up their seed round, valuing the company at $12 billion. This was one of the largest seed rounds in history.

Mira Murati may change the existing, albeit infant paradigm of AI. She’s anything but foolish.

Bubble Bubble toil and trouble.

Like I said the dot con MBAs often knew to sell out. Those guys were nowhere to be found when the bubble burst.

Take the money and go screaming into the night.

Note that is $12 billion down the drain. In all likelihood you wont be impressed later on.

There is nothing like being paid what you are worth. An honest living.

Then there is garbage talk in silicon valley.

This comes out of your wallet and produces nothing.

A.I. Researchers Are Negotiating $250 Million Pay Packages. Just Like N.B.A. Stars.

The NBA actually creates revenues to match pay.

What does that mean?

If you say there is a progression what is it?

“infant paradigm” is just marketing garbage.

I think China gets these chips because they are a waste of money and do not present a military threat.
