The money didn't leave. It changed seats.

The Nasdaq dropped 1.47% and the equal-weight index gained 1.0%. Same session. That's not a stampede, it's a reshuffle.

THE NUMBER

+12.5%

year-to-date gain left in the AI momentum basket

A month ago, on 22 June, that same basket was up 60% on the year. By 16 July it was up 12.5%. One month erased nearly 48 points of annual return while the rest of the market barely moved.

THE DATA

ONE MONTH

From +60% to +12.5% in a month

-47.5 pts

▼ from +60% (22 Jun) to +12.5% (16 Jul)

Imagine being told your year is no longer up 60% but up 12%. And nothing changed in the companies' books.

This isn't the market falling. It's the giving back of a return that had piled into very few names in very little time.

POINT: — A unit of return. Going from +60% to +12.5% is 47.5 points lost.
DRAWDOWN: — The fall from the peak. It measures real pain, not the calendar-year return.

QUOTE

THE READ

An orderly unwind

“Money leaving a bubble doesn't leave the market on day one. First it spreads into everything else. Only when the fall gets big enough does it drag the whole thing down with it.”

Ronfy Analysis · Editorial

Goldman Sachs Research calculates that stripping AI out of the momentum basket takes the monthly drop from 17.3% to 5.1%. Seventy percent of the damage has one name on it.

ROTATION: — Money moves between sectors without leaving equities.
CAPITULATION: — The day everyone sells at once. It usually marks the low.
PRIME BROKERAGE: — The books where hedge funds hold their leveraged positions.

THE SESSION

16 JULY

One session, five different realities

The Dow barely flinched because it holds almost no AI. Semiconductors lost 4.2%. The market didn't fall. A slice of it did.

Every number here is from the same Thursday. Look only at the S&P 500 and you miss that half the market was green.

RSP: — The equal-weight S&P 500 ETF. All 500 companies carry the same weight.
SMH: — The semiconductor ETF. The thermometer for the AI trade.
DOW: — An index of 30 large companies with little tech weighting.

BOTH SIDES

WHO PAYS

The seat emptying and the seat filling

THE SEAT EMPTYING

The AI momentum basket

Down 17.3% on the month per Goldman Sachs Research. Strip out AI and the drop is just 5.1%.
Its volatility is running like a VIX near 80, while the index VIX sits at 18.
Momentum exposure in big funds' books has fallen to the 77th percentile over one year. Still high: not everyone has left.

THE SEAT FILLING

The average stock

The equal-weight S&P 500 rose 1.0% on the same Thursday the Nasdaq lost 1.47%.
More stocks advanced than declined, despite the red headline on the main index.
This is the classic first phase: money hunts for the average, not for the exit.

A rotation always has two sides. The headline only shows you one.

77TH PERCENTILE: — Of the last year's 100 days, 77 had less exposure than today.
VIX: — The fear index. It measures expected volatility on the S&P 500.

ANATOMY

WHERE IT COMES FROM

Seventy percent of the damage has one name

THE AI COMPONENTWithout it the drop would be 5.1%70%

THE REST OF MOMENTUMDragged down, not thesis-broken30%

When 70% of a drawdown comes from one theme, you don't have a market problem. You have a concentration problem in that theme.

Goldman Sachs Research split the momentum basket in two: with AI and without. The gap explains almost everything.

AI CAPEX: — What big tech spends on data centres and chips.
BASKET: — A group of stocks bundled by a shared trait so they can be measured together.

WATCHLIST

6 TO WATCH

Six names that tell the whole session

RSP	212.97	▲ +1.0%	Equal weight. The proof that money rotated inside equities rather than out.
SMH	590.77	▼ -4.2%	Semiconductors. The exact epicentre of the AI unwind.
GOOGL	354.46	▼ -4.4%	Wiped roughly $200bn after reports its most powerful AI model slipped behind schedule.
SNDK	1,411.08	▼ -12.6%	Storage. The link most levered to data-centre demand.
NFLX	67.87	▼ -9.6%	After hours. Results in line, but guidance landed 1.2% below consensus.
VIX	18.35	▲ +9.7%	Up, but still under 20. The fear is sector-level, not index-level.

Each one shows a side of the rotation. Together they explain why the index fell little and the scare felt big.

GUIDANCE: — The company's own forecast. Markets punish it harder than the results.
AFTER HOURS: — Trading that happens after the official US close (16:00 ET).
ETF: — A listed basket that tracks an index or a sector.

WRAP

Did this briefing help?

If you now see how a red index can hide a green market, send this to someone who only reads the headline.

One carousel a day, Monday to Friday. Tomorrow another story, another concept.
