AI stocks are increasingly moving in the opposite direction of the rest of the market: The 40-day correlation between the US Broad AI Index and the S&P 500 ex-AI Index is down to -0.60, the lowest on record. The correlation has now been negative since late-June, marking only the 2nd negative reading on record after July 2024. This also marks a sharp reversal from the +0.65 positive correlation seen in mid-May. In other words, AI stocks are increasingly diverging from the broader market, suggesting capital is rotating between AI and non-AI stocks. This comes after the US AI Index surged +160% since April 2025, significantly outperforming the S&P 500 ex-AI Index, which gained ~35%. The AI trade is becoming increasingly independent of the broader market.

@KobeissiLetter That’s a major shift. AI stocks are clearly carving out their own path from the broader market.

@KobeissiLetter That’s a pretty wild rotation. AI isn’t just outperforming anymore, it’s starting to trade like its own little market.

@KobeissiLetter So AI stocks are now the market’s opposite day, guess they finally got the memo that being contrarian pays off. x.com/orsinivanessa3/status/20…

@KobeissiLetter What does the correlation distribution across individual AI names look like beneath this index level reading?

@KobeissiLetter when one basket funds the other you don't get diversification, you get correlation risk that shows up exactly when you need it not to

@KobeissiLetter It is a bit concerning. Be sure to have some dry powder ready for a serious pullback.

@KobeissiLetter AI stocks have officially become their own weather system. The rest of the market gets a forecast, they get an evacuation map.

SwitchWize @switchwize · D

Worth flagging: this isn't just one shop's read. Goldman's own AI basket shows the same thing - correlation to the broader S&P 500 has also flipped negative, a record low, using a completely different methodology. Two independent measurements landing on the same signal is the real story: "the market" is increasingly two markets sharing one index. If your diversification is by ticker count and not by AI-exposure, you're carrying more concentration risk than the number of names in your portfolio suggests.

A -0.60 correlation is a powerful signal of market segmentation, not necessarily a verdict on AI’s long-term prospects. When performance becomes this concentrated, liquidity, positioning and expectations can matter more than fundamentals in the short run. The key question is whether capital is rotating towards genuine earnings growth or simply chasing recent winners. Either way, concentration risk deserves as much attention as headline returns. 📊⚖️ Please read my latest X: x.com/tekkaus/status/209223961…

@KobeissiLetter yeah this negative correlation really shows how crowded the AI trade is getting tbh

Macro Alpha @MacroAlphaHQ · A

@KobeissiLetter Negative correlation means AI outperformance now draws capital directly from ex-AI names rather than expanding total market liquidity.

InsomniaLK @InsomniaLK · D

@KobeissiLetter Splitting up. Finally.

Rohan Tantia @RohanTResearch · D

@KobeissiLetter How long can this divergence continue before valuations, earnings or liquidity force the two trades back together?

Matthew @thebankersdozen ·

@KobeissiLetter Here is a look at the correlation delta on $NVDA less the average for $DJIA names over the past 100 days - definitely a shift x.com/thebankersdozen/status/2…

Trademaster Academy @TMA_MarketIntel ·

This is the dispersion trade in full force. When the AI vs non-AI correlation goes negative, single-name options flow tells the real story before the index does. We're seeing capital rotate on a daily basis, not a monthly one. The risk is if that -0.60 correlation snaps back fast, both sides unwind at once and volatility spikes across the board. Watching the gamma positioning here closely.

North Macro @NorthMacro · C

-0.60 on a 40-day correlation means AI and non-AI aren’t just moving differently; they’re actively offsetting each other. Since late-June, trimming the crowded AI winners has become the other side of buying what got left behind. For index investors, the S&P can look calm while the fight underneath is anything but.

@KobeissiLetter @grok Compare this correlation to NASDAQ100 (QQQ).

@KobeissiLetter The personal saving rate is a residual, not a behavior. It is disposable income minus outlays, and that income excludes realized capital gains. Sell appreciated stock, spend the proceeds, and the accounts see consumption and no income. Two years of gains do this alone.

Reasonus4 @reasonus4 · A

@KobeissiLetter DOMESTIC AI SECTOR IS BANKRUPT And $NVDA cannot sell to the only market that is solvent: China - because of Trump’s stupid trade war. AI is Infra and #China has it. US spent $15.4TRN on Israel’s wars instead of infra. The US cannot roll out AI! x.com/reasonus4/status/2092437…

@KobeissiLetter Negative correlation means AI is becoming its own factor rather than market beta. That raises diversification value, but also concentration risk: index direction can hide different earnings and valuation regimes.

@KobeissiLetter money isn't leaving the market. it's just switching seats

ByShovelLLC @ByShovelINC · D

@KobeissiLetter a -0.60 rolling correlation means AI is now functioning as a sector-sized hedge against its own economy, which is the kind of thing that sounds like a feature until it isn't.

Takeshi Kovacs @technotorgun · D

@KobeissiLetter Deeply negative correlation after a massive AI surge is classic late cycle behavior. Capital rotation is the real story.

@KobeissiLetter Correlation breakdown, not just a slowdown. A -0.60 40-day correlation between AI and non-AI equities is the most negative on record, only the 2nd such reading since 2024. This isn't broad risk-off

web3 lawyer 首席大律师 @Web3Counsels · D

@KobeissiLetter that -0.60 reads like exhaustion, not rotation. july 2024 did the same thing and ai names dropped ~20% in six weeks while spx chopped. crowded longs decoupling before liquidation. what happens if nvda breaks the june low?

Worth looking under the price divergence: across NVDA, MSFT, GOOGL, META, and AVGO, capital allocation quality doesn't show a debt-fueled buildout. MSFT, GOOGL, META, and AVGO have been consistently self-funded from operations across their full available history. NVDA is the more interesting case — an ordinary growth-financed profile in 2021-2022, a dip into financing-dependence in 2023 during its steepest buildout year, and a full recovery to self-funded and stable every year since. The price move may be decoupling from the broader market; the underlying capital structure isn't telling a story of leverage propping it up.

Second Order Research @SecondOrderRes · D

This is actually pretty interesting. A -0.60 correlation doesn’t just say “AI is doing its own thing” — it suggests the market may be actively rotating between AI and everything else. If that keeps up, broad index performance could hide a lot more dispersion under the surface. Feels like stock selection matters a lot more in that kind of tape.

MacroDelta @GianluBol ·

@KobeissiLetter AI is no longer moving with the broader market. A -0.60 correlation signals a major rotation beneath the surface. AI remains strong, but market leadership is becoming increasingly fragmented. #AI #Markets #MacroDelta

ROY_INVEST @Roy3748973 ·

@KobeissiLetter That divergence is the key signal 👀 AI isn’t just leading the market anymore—it’s increasingly trading like its own asset class.

@KobeissiLetter That’s a pretty clear sign the AI trade is becoming its own market story, not just another leg of the broader rally.

Wouter Born @wouter_born · D

@KobeissiLetter This is what happens when a theme stops being a "trade" and becomes an asset class. Semis, hyperscalers, and software-AI plays are starting to trade on their own fundamentals, not on SPX beta.

@KobeissiLetter AI is developing independent market dynamics.
