RISK · ALERTBig Tech's earnings engine stalls in 2028
The megacaps carried the index's earnings for two years. The math starts to reverse just as spending peaks.

THE NUMBER

↓ megacaps' contribution to index earnings in 2028
Big Tech added +11 points to S&P 500 earnings per share this year, dropping to +7 in 2027. In 2028 it turns negative (-1 point), as short-life chips get written down.
THE NUMBER
ZOOM IN-1 point
-1 pp
▼ from +11 pp in 2026 · capex write-downs
It's like a company that earns a lot while spending little, until the bills for everything it bought come due. In 2028, the chip bills arrive.
Big Tech's boost to index earnings moves from +11 pp (2026) to +7 pp (2027) to -1 pp in 2028. The tailwind becomes a headwind.
- CAPEX
- — Capital spending (data centers, chips). It inflates future costs today.
- TAILWIND
- — A force pushing in your favor. Here, the extra profit from AI.
QUOTE
AUTHORITYThe bounce the smart money doesn't buy
“An internal panic gauge jumping from 1 to 7.4 in a week explains the technical bounce. But the smart money's positioning in AI has been falling since June.”
While banks raise price targets, institutional positioning has cut AI by 7 points since June. A classic divergence.
- POSITIONING
- — How much risk the smart money has on. It tends to lead their moves.
- OVERSOLD
- — A drop sharp enough to trigger a short-term technical bounce.
- DIVERGENCE
- — When two signals disagree: here, price rising while positioning falls.
TREND
EPS BOOSTThree years, three earnings regimes
The year the boost crosses below zero is the year the infinite-margin story stops holding up on its own.
The megacaps' boost to index earnings isn't constant: it pushes hard, cools off, and ends up subtracting.
- BOOST
- — How much a group of companies adds to the index's total earnings growth.
- MARGIN
- — Profit left from each dollar of sales. AI inflated it; capex pressures it.
CONSEQUENCES
WHAT IT MEANSThree things that change when the boost runs out
MULTIPLES WITHOUT A NET
If earnings stop growing at the old pace, paying 30 or 40 times earnings stops being justified by future growth.
INDEX CONCENTRATION
A handful of names moves the S&P 500. If their earnings wobble, they drag the whole index even if the other 490 are fine.
CAPEX THAT WON'T STOP
Spending on data centers and chips keeps rising just as its contribution to earnings starts falling. The math tightens from both sides.
If the megacaps' earnings stop growing, the price the market pays for them hangs in the air.
- MULTIPLE
- — What the market pays for each dollar of earnings (the P/E is the most common).
- CONCENTRATION
- — When a few companies weigh so much they decide the index's move.
EXAMPLE
DEFENSIVE IDEAA sample mix for an earnings peak
The idea isn't to flee AI, it's to not bet the whole portfolio on earnings growing forever. Illustrative example.
This is NOT advice. It's an illustrative example of a more defensive mix when the megacaps' earnings engine cools.
- CASH FLOW
- — The real money left after paying everything. Harder to dress up than profit.
- VALUE
- — Investing in cheap, solid companies rather than bets on future growth.
WATCHLIST
5 NAMESFive names that told Monday's story
| INTC | indic. | ▲ +5.1% | Rose on a JPMorgan upgrade. A bounce driven by banks, not by new earnings. |
| AMZN | indic. | ▲ +5.5% | Morgan Stanley top pick with a 350 price target. Quality with real cash flow. |
| TSLA | indic. | ▲ +4.1% | An oversold bounce in a high-beta name. Rises fast, falls fast. |
| QQQ | indic. | ▲ +1.6% | The Nasdaq-100. It concentrates the megacaps: if their earnings wobble, it feels it first. |
| SGOV | indic. | → 0.0% | Ultra-short Treasury bills. The refuge paying ~4% while direction gets decided. |
Monday's bounce came from bank upgrades on specific names. Levels are indicative; what matters is the why behind each one.
- BETA
- — How much a stock moves relative to the market. High beta = roller coaster.
- PRICE TARGET
- — The level a bank thinks a stock should trade at.
