A favorite big-picture yardstick for stock valuations is flashing hot again. The Buffett Indicator, which compares the total U.S. stock market to the size of the economy, is hovering around the 216 to 221% zone this week.
Advisor Perspectives’ latest update puts the ratio at 215.6% after the government’s third estimate of second-quarter GDP, while GuruFocus pegs it at 220.8%.
Both are among the highest readings on record and well above long-term norms.
The lofty reading arrives as Berkshire Hathaway, Warren Buffett’s conglomerate, sits on an extraordinary pile of liquidity.
As of June 30, Berkshire reported roughly 96.2 billion dollars in cash and cash equivalents at its insurance and other operations, plus 243.6 billion dollars in short-term U.S. Treasury bills, with another 4.3 billion dollars in cash at its railroad, utilities and energy businesses.

That adds up to about 344 billion dollars in cash and T-bills at midyear, near an all-time high for the company.
Investors have long treated the Buffett Indicator as a blunt but useful warning light. When the market’s total value balloons far faster than economic output, forward returns tend to moderate and the margin for error shrinks.
Today’s reading is not an oracle, but it lands after a year when Nasdaq notched an all-time high, fueled by a narrow cohort of mega-cap winners that pushed the broader equity market to premium multiples.

Elevated valuations do not guarantee a pullback, yet they leave less room for disappointment if earnings growth cools or policy winds shift.
Berkshire’s posture amplifies that message. The company’s 10-Q shows a war chest anchored in short-dated Treasurys and cash that gives it ample dry powder, and it has been content to wait for better prices. That stance has precedent.
During past bouts of market stress, Berkshire deployed capital quickly into preferred equity or negotiated deals.
The ability to move with speed is the point of holding so much liquidity, but the absence of big buying speaks to what the firm sees across today’s opportunity set.
For everyday investors, the pairing of a stretched valuation gauge and Berkshire’s cash fortress suggests a few practical takeaways.
First, index-level returns may be more volatile from here, especially if earnings revisions fail to keep pace with optimistic multiples.

Second, quality balance sheets and dependable cash flows can matter more late in the cycle than during a liquidity-fueled melt-up.
Third, cash is not dead money when short-term government paper pays a positive real yield, which helps explain Berkshire’s patience while it waits for a fat pitch.
None of this requires a recession to play out, but it does argue for sharper risk control and realistic return assumptions.
Seasonality is a weak compass, yet investors know the fall calendar can test nerves. September’s reputation as a difficult month is not superstition so much as a reminder that momentum can stumble once macro and earnings calendars take over.
As this year’s moves showed, narrative-heavy surges can stretch even further than skeptics expect, and then retrench just as quickly when rates, profits or policy headlines intrude.
That is why Berkshire’s choice to sit tight reads as a signal as much as a tactic.
Stocks are priced for near-perfect execution, and if that persists, gains are likely to be steadier and more selective than the broad rallies that lifted indexes earlier in the year.
If it does not, investors who kept some cushion may find better entry points in the months ahead.
