My contrarian instincts usually kick in once I see the gang reaching a questionable consensus. More often than not, what the gang does IS the market; what they are saying, nevertheless, is commonly suspect.
Over the previous few years, the gang has anticipated fast Federal Reserve fee cuts that by no means materialized; there have been repeated expectations in 2022, ’23, and ‘24 of an imminent recession that by no means occurred; the fears brought on by market focus appear to have additionally been ignored by Mr. Market.
Then there’s the countless cacophony of bubble chatter.
I can not recall ever listening to the gang determine a bubble in actual time, after which there really a) being a bubble that b) burst quickly after. By definition, the gang creates bubbles by way of a mix of psychology, greed/FOMO, extra liquidity, and sheer recklessness.
Approach again in 2011, I attempted to create a guidelines of the way to spot a bubble in real-time. With the good thing about time and hindsight, it’s straightforward to see the affect of the Nice Monetary Disaster on that record. It’s 14 bullet quantitative factors that ought to help you see if any market is exhibiting bubblicious tendencies.
Let’s undergo these 14 factors to see how they maintain up in the present day:
Normal Deviations of Valuation: Markets are dear, however not Japan 1989/1999-2000 Dotcom dear
Considerably elevated returns: The previous 15 years have seen returns of 16% yearly. That is the third-best rolling 15-year interval since WW2, but it surely additionally follows a 57% GFC crash. The previous two years 25% yearly. 2023-24 definitely counts as elevated.
Extra leverage: Whereas there are some leveraged merchandise put there like 2X and 3X ETFs, it’s hardly a significant quantity of capital (the identical was mentioned about Subprime, however that was wildly infiltrated all through the whole thing of the monetary system)
New monetary merchandise: Alts? Non-public Credit score? Neither is a lot “New” as newly well-liked.
Growth of Credit score: Principally tight, not very accessible.
Buying and selling Volumes Spike: NYSE common each day buying and selling quantity (ADV) is roughly 1.36 billion shares – considerably above historic common of 900 million to 1.2 billion shares per day. NASDAQ common each day volumes has exceeded 9 billion shares by way of 2025. ADV ranges 6–8 billion shares each day, so exercise this 12 months is effectively above common.
Perverse Incentives: I’m not conscious of a lot right here apart from the land seize in alts, the massive variety of new ETFs, and the return of meme inventory buying and selling.
Tortured rationalizations: These are ever-present, however there was some uptick these days.
Unintended Penalties: Have but to completely occur.
Employment developments: Full employment is offset by eye-watering salaries for AI engineers.
Credit score Spreads: Are very tight, and make me marvel why anybody would wish to personal HY when IG is sort of the identical pricing
Credit score Requirements: Nonetheless tight for the reason that GFC.
Default Charges: Low, however transferring increased in autos, bank card, mortgage however particularly pupil mortgage debt.
Unusually Low Volatility: VIX atr 20 shouldn’t be precisely complacent; as we noticed in April, VOL has been fast to reply to any subject…
So whereas there are some indicators of bubblicious exercise, it’s hardly overwhelming or significantly determinative in my opinion. Shares are dear, however this appears much less like a bubble and extra like a later stage bull market cycle.
Earlier this 12 months, I famous what a spectacularly underappreciated 15 years we have now loved. The bubble discuss seems to be like much more of the identical…
Bear in mind, Greenspan’s “Irrational Exuberance” speech was December, 1996. All bull markets run additional, longer, and better than most count on…

1996 22.96
