That 10-word warning is Buffett calling out a market driven more
by speculative momentum and derivatives than fundamental value.
What History Says Happens Next
When historical valuation measures and
speculative froth reach these levels, the playbook rarely ends with
a quiet sideways drift:
Subdued or
Negative Forward Returns:Historically, whenever the market CAPE
ratio pushes past 39–40, subsequent 1-to-3-year forward returns
flatten out or turn sharply negative. It doesn't mean a crash
happens tomorrow, but the math dictates that future expected
returns are getting borrowed against the present.
The Unwind
Hazard:When leverage gets this heavy (record margin balances
and massive short-term options volume), any macro shock or
unexpected hawkish pivot tends to trigger forced liquidations.
Margin calls accelerate downside momentum far faster than organic
selling.
The Value
Playbook:For long-term capital allocators, periods like this
usually mean holding cash equivalents (just like Berkshire's
massive cash pile) and waiting patiently until the speculative
washout offers rational entry points again.
People write about the size of margin debt in absolute terms,
and some compare it to GDP, but the correct denominator IMO is
market cap. I don't have the numbers in front of me, but
compared to market cap it is not that crazy. Even when one
adds in the debt of leveraged ETFs, which are actually not that
large compared with the overall equity market, it's high but not
off the charts.
As regards a CAPE of 40+, which is indeed very expensive, I have
been concerned about that for a while, to my detriment. But
there is no hard limit at the previous high of 44. Remember
Japan went to a CAPE of 100. They had a simultaneous property
+ equity bubble, and I would not wish that on anyone. And
that is why it took decades to work off, instead of only one
decade, like the dot com bubble took the US to digest.

Buffet's been warning for months. Is this the end? no.
