Valuation Warnings Ignore The One Thing That Actually Moves Markets

Valuation warnings cite the Shiller CAPE ratio - the S&P 500's price divided by a 10-year average of inflation-adjusted earnings. It's sitting at about 41.4, near the level that preceded the dot-com crash.

Of course, this is completely false as a framework.

Not because valuations don't matter - they do. But because the CAPE ratio is a snapshot, not a driver. It tells you where price sits relative to smoothed earnings. It doesn't tell you where the liquidity that sustains that price is heading. And the liquidity cycle is the master variable for all asset prices.

Let's look at what's actually happening.

M2 Is Growing Again

U.S. M2 - the broadest widely followed measure of money supply - hit a record $23.16 trillion in June 2026. That's up 4.7% year-over-year, roughly $1 trillion more than a year ago, and above the $21.9 trillion peak reached in March 2022. After a period of post-pandemic monetary contraction, the money supply has resumed growth.

The Fed's balance sheet stands at $6.7 trillion as of late July, down a trivial $9 billion week-over-week but over $95 billion higher than a year ago. Quantitative tightening slowed to a crawl and liquidity facilities are sitting loaded - meaning the plumbing is primed to expand if conditions require it.

When M2 contracts, risk assets compress. When M2 expands, they stretch. This isn't theory. It's the relationship that repeated itself through 2008-2009, 2013-2021, and the selloff of 2022. The current inflection - money supply growth turning positive again - matters far more for what happens to equities than the CAPE's current reading.

The Economy Is Accelerating, Not Fraying

The CAPE argument implicitly assumes we're in a late-cycle slowdown heading into a downturn. The data says otherwise.

The ISM Manufacturing PMI jumped to 55.6% in July 2026, up from 53.3% in June. That's the strongest expansion in factory activity since May 2022. The employment sub-index returned to growth territory at 52.8% for the first time in 33 months. Production hit 58.5%. New orders are expanding. Backlogs are growing. This is the 21st consecutive month of overall economic expansion.

CAPE Has Been "Warning" for Decades

There's a more fundamental problem with the CAPE as a timing tool. Since 1996, the U.S. CAPE ratio has been above its long-term historical average of 16.6 roughly 96% of the time. If the metric had been flashing a crash warning for 30 of the last 31 years, it's not really a warning signal - it's a description of a regime shift.

The index composition changed. The S&P 500 is now dominated by asset-light, high-margin technology businesses with durable growth profiles. Applying the same earnings-smoothing framework that was calibrated on capital-intensive industrials from the 1950s through the 1990s to an index where a third of the value comes from AI-exposed tech is a category error.

And if you had exited equities in 2018 when the CAPE last topped 32, you would have missed roughly a 13.7% annualized return through 2026, inclusive of dividends. The metric can tell you when valuations are historically rich. It cannot tell you when the liquidity cycle that sustains those valuations is about to reverse.

What Crypto Is Telling Us

Crypto is macro and macro is crypto. The behavior of digital assets right now tells a different story from the CAPE fear-mongering.

Bitcoin is at $64,450, down 29% over the past 250 days and 6.6% year-to-date. The Fear and Greed Index sits at 25 - extreme fear. Total crypto market cap is $2.2 trillion, with Bitcoin dominance at 58.9%. Ethereum is at $1,902.

When sentiment in the most liquidity-sensitive asset class hits fear extremes while M2 is expanding and ISM is surging, that's not a market about to crash. That's the kind of divergence that tends to precede sharp mean reversion. In Q4 2022, literally EVERYONE was bearish on crypto. The global liquidity cycle had just bottomed. What followed was one of the largest rallies in both markets.

The Real Watchpoint

The CAPE ratio is high. That's not in dispute. But high valuations persist as long as the liquidity that sustains them keeps flowing. The question is not whether the S&P 500 is expensive by historical standards - it is. The question is whether the liquidity cycle is turning.

Right now, the data says it isn't. M2 is growing. Manufacturing is accelerating. The economy is in its 21st straight month of expansion. Sentiment in crypto is at fear extremes.

What would change this view? A sustained reversal in M2 growth back into contraction territory. The ISM PMI falling below 50 and staying there. The Fed restarting aggressive balance sheet reduction.

Those are the signals that would align with what the CAPE is already telling you. Until then, the chart-wallahs are reading the rear-view mirror while the engine is still running.

The Big Picture

Valuation extremes are not self-fulfilling prophecies. They're sustained - or destroyed - by the liquidity cycle. The CAPE tells you the S&P 500 is expensive. M2, ISM, and sentiment tell you the conditions that keep expensive markets expensive are still in place. Follow the liquidity, not the lagging valuation ratio.

Good luck out there.
