Led by Scott Chronert, the strategy team proposed replacing the Mag 7 with "Growth Cluster" as a new framework for assessing AI investment opportunities in U.S. stocks. This conclusion comes just as the earnings season for the Mag 7 kicks off—Alphabet and Tesla will be the first to disclose their results on Wednesday, and the market is holding its breath to see if the massive capital expenditures in AI can translate into sustainable profit growth. ## Mag 7 "is dead": Internal correlations have collapsed, five underperforming the market The Chronert team bluntly stated in the report: "In our view, the Mag 7 as a framework for assessing large-cap growth dynamics is dead, and has been for some time." The core basis for this judgment is that the price correlations among the seven stocks have completely collapsed. Due to the different positions of each company in AI infrastructure investment, their stock price trends have diverged significantly. Microsoft and Meta have fallen due to market skepticism about whether their massive capital expenditures will yield returns; Apple, on the other hand, has been well-received by the market for choosing not to participate in the data center arms race and for its restrained capital expenditures, rising 23% this year. Broadcom's weight in the S&P 500 surpassed that of Meta and Tesla earlier this year, triggering Citigroup to reassess the Mag 7 concept. Data confirms this divergence. This year, only Apple among the "Magnificent Seven" has outperformed the market, while Microsoft has become the biggest loser with a 19% decline year-to-date. The Bloomberg Mag 7 index has risen only about 1.1% so far in 2026, while the NASDAQ-100 index has increased nearly 18% and the S&P 500 index has risen about 10%. ![0e96ea0dc010b6c19f50369b9e66dda5.png](https://imageproxy.pbkrs.com/https://img.zhitongcaijing.com/image/20260720/1784545611119951.png?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg) ![1d562359aa2bf772900bb2ef282b71c2.png](https://imageproxy.pbkrs.com/https://img.zhitongcaijing.com/image/20260720/1784545619202284.png?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg) Citigroup strategists draw an analogy with the demise of FAANG: "When was the last time you thought of FAANG?" Once upon a time, FAANG was synonymous with tech stock investment, but now few mention it. Chronert believes that the Mag 7 is at the same turning point—this label not only fails to explain the evolution of AI trading but increasingly obscures the true picture of the market ## "Growth Cluster" New Framework: Over Half of Market Value, Nearly Half of Profit Contribution Citigroup's alternative proposal is a broader framework called "Growth Cluster." This combination not only includes large tech stocks but also covers most companies benefiting from AI infrastructure development—such as semiconductor companies, data center operators, and more. The Growth Cluster accounts for more than half of the total market value of the S&P 500 index and contributes nearly 48% of profits. Chronert believes that compared to the binary division of "Mag X vs the rest of the index constituents," the Growth Cluster more accurately reflects the fundamentals and price dynamics of the index. ![231f96774147ee93a8e7392a231bfa55.png](https://imageproxy.pbkrs.com/https://img.zhitongcaijing.com/image/20260720/1784546147451822.png?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg) In terms of valuation, the cluster's 12-month forward price-to-earnings ratio is at the 66th percentile of the same period over the past 30 years, and the earnings expectations for 2027 remain strong. Citigroup data shows that the earnings expectations for the Growth Cluster have consistently exceeded expectations and have been revised upwards, "with the magnitude of its earnings expectation revisions nearing the surreal." Citigroup categorizes all sectors of the S&P 500 into three clusters—cyclical, defensive, and growth. Semiconductors and semiconductor equipment, software and services, technology hardware and equipment, media and entertainment, automotive and parts, etc., are all included in the Growth Cluster. Chronert points out that while there are controversies over individual classifications (such as Tesla dragging the automotive sector into the Growth Cluster and Amazon bringing non-essential consumption and retail into it), overall, the three-cluster framework helps tell the true story of the market. ![28932ddf2ea91b40f9987d7d0339b9fa.png](https://imageproxy.pbkrs.com/https://img.zhitongcaijing.com/image/20260720/1784546162991697.png?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg) ## $3.2 Trillion Fund Rotation: Shift in AI Trading Logic Citigroup's framework adjustment suggestion is based on a large-scale market rotation that has already occurred. Data shows that as of mid-July, the total market value of the "seven major tech giants" in the U.S. stock market increased by about $1.5 trillion in July; in contrast, the market value of the semiconductor sector, excluding Nvidia, shrank by nearly $1.7 trillion during the same period. This constitutes a large inter-sector fund rotation of approximately $3.2 trillion. Meanwhile, the traditional software sector, which had previously been squeezed by the AI concept, rebounded significantly, with 44 out of 51 major software companies monitored showing increases, and the median monthly increase reaching 6%. The essence of this rotation is the shift in AI trading logic from "capital expenditure side" to "beneficiary side." Interactive Brokers' chief strategist Steve Sosnick uses a cruise ship metaphor: "Investors are moving from AI Manufacturers 'rotate back to AI' users. Just like people on a cruise ship move from one side to the other when that side becomes too crowded, and then move back again. The behavioral changes of retail investors are particularly evident. Data from Vanda Research shows that individual traders' buying power for the Magnificent Seven has continued to weaken, with funds flowing into new AI sub-sectors—such as memory chip companies like SK Hynix. Citigroup pointed out that during the five trading days ending July 17, retail investors accounted for only 6% of the trading volume of the Magnificent Seven, a four-year low. Chronert accurately predicted last December that by 2026, AI trading would shift from technology "enablers" to technology "adopters." This shift is currently gradually unfolding in the market—after leading gains in semiconductor stocks in the first half of 2026, they have begun to perform poorly in recent weeks due to valuation concerns. Meanwhile, strategists like Manish Kabra from Société Générale warn that it is still too early to buy into the companies with the largest capital expenditures in the AI field. The market is actively debating which segment of the AI ecosystem—builders, enablers, or adopters—will generate excess returns in the next phase. However, Kabra does not believe the AI boom has ended; rather, he judges that the market needs a "relief pullback" for investors to re-engage. **The Key Test of Earnings Season: AI Capital Expenditures Enter the "Profit Validation" Moment** Citigroup's declaration that the Magnificent Seven is "dead" comes at a rather delicate moment—this week is a critical window for the concentrated release of earnings reports from the seven giants. According to FactSet, the Magnificent Seven's second-quarter earnings are expected to grow by 31.1% year-on-year, higher than the 22.8% growth of the other S&P 500 constituents. The Roundhill Magnificent Seven ETF (MAGS), which tracks the seven giants, has rebounded over 4% since July, halting a 9% monthly decline in June. ![6180ffdbe20acc31fbe8ac36a5d43ab6.png](https://imageproxy.pbkrs.com/https://img.zhitongcaijing.com/image/20260720/1784546679286760.png?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg) However, whether the earnings reports can truly become a catalyst remains highly uncertain. Alphabet, Microsoft, Amazon, and Meta are expected to have a combined capital expenditure of up to $725 billion this calendar year, which is projected to rise to nearly $900 billion by 2027. The market is urgently questioning: when will such a massive investment in AI translate into sustainable profit growth? Apollo Global Management points out that the earnings per share growth rate of the "Magnificent Seven" is expected to slow to 20% by 2026 and further decline to 15% by 2027. The market is shifting from a "growth narrative" to "profit validation." ## Conclusion: From Mag 7 to Growth Clusters, the Rotation of AI Investments Citigroup declares that Mag 7 is "dead," which not only signifies an update in strategic frameworks but also reflects a profound shift in the AI investment cycle from "narrative-driven" to "profit verification." For three years, the "seven giants" have been synonymous with the bull market in U.S. stocks—2023 and 2024 are precisely the years when these seven stocks have driven the S&P 500 to new highs. Now, as AI infrastructure enters a "burn rate mode," the market is beginning to distinguish between who are the "beneficiaries" of AI and who are the "spenders" on AI. Citigroup's "growth cluster" framework is a systematic response to this structural change. Citigroup's new framework aims to go beyond the simple binary opposition of "Mag X versus the rest of the index." Chronert believes that the "growth cluster" can more accurately reflect the fundamentals and price performance of the S&P 500 index. This framework shift may accelerate the rotation of capital from mega-cap tech stocks to other sectors or mid-cap growth stocks, but Citigroup emphasizes that this cluster will still be the main driver of market gains. As the internal rate of return among the seven giants diverges, the logic of AI investment shifts from "who is spending" to "who is benefiting," and as the growth cluster's profit growth outpaces that of defensive sectors by four times, the Mag 7 label indeed struggles to encapsulate the complexity of the market. As Chronert stated, "This has happened before." From FAANG to Mag 7, and from Mag 7 to growth clusters—the evolution of market labels has always been a reflection of changes in underlying investment logic. For investors, the real challenge is not to remember the new labels, but to accurately identify the true creators of value at the turning point where AI investment shifts from "arms race" to "profit realization." ### Related Stocks - [MSFT.US](https://longbridge.com/en/quote/MSFT.US.md) - [.SPX.US](https://longbridge.com/en/quote/.SPX.US.md) - [AAPL.US](https://longbridge.com/en/quote/AAPL.US.md) - [.NDX.US](https://longbridge.com/en/quote/.NDX.US.md) - [AAPU.US](https://longbridge.com/en/quote/AAPU.US.md) - [VOO.US](https://longbridge.com/en/quote/VOO.US.md) - [MSFD.US](https://longbridge.com/en/quote/MSFD.US.md) - [MSFO.US](https://longbridge.com/en/quote/MSFO.US.md) - [AAPB.US](https://longbridge.com/en/quote/AAPB.US.md) - [MSFX.US](https://longbridge.com/en/quote/MSFX.US.md) - [AAPX.US](https://longbridge.com/en/quote/AAPX.US.md) - [MSFU.US](https://longbridge.com/en/quote/MSFU.US.md) - [MSFL.US](https://longbridge.com/en/quote/MSFL.US.md) - [AAPD.US](https://longbridge.com/en/quote/AAPD.US.md) - [QID.US](https://longbridge.com/en/quote/QID.US.md) - [SPLG.US](https://longbridge.com/en/quote/SPLG.US.md) - [MSFW.US](https://longbridge.com/en/quote/MSFW.US.md) - [MSFY.US](https://longbridge.com/en/quote/MSFY.US.md) - [MAGX.US](https://longbridge.com/en/quote/MAGX.US.md) - [QLD.US](https://longbridge.com/en/quote/QLD.US.md) - [TQQQ.US](https://longbridge.com/en/quote/TQQQ.US.md) - [PSQ.US](https://longbridge.com/en/quote/PSQ.US.md) - [SPY.US](https://longbridge.com/en/quote/SPY.US.md) - [SQQQ.US](https://longbridge.com/en/quote/SQQQ.US.md) - [QYLD.US](https://longbridge.com/en/quote/QYLD.US.md) - [JEPQ.US](https://longbridge.com/en/quote/JEPQ.US.md) - [QQQI.US](https://longbridge.com/en/quote/QQQI.US.md) - [IVV.US](https://longbridge.com/en/quote/IVV.US.md) - [SPXL.US](https://longbridge.com/en/quote/SPXL.US.md) - [UPRO.US](https://longbridge.com/en/quote/UPRO.US.md) - [SSO.US](https://longbridge.com/en/quote/SSO.US.md) - [SH.US](https://longbridge.com/en/quote/SH.US.md) - [SPXS.US](https://longbridge.com/en/quote/SPXS.US.md) - [SPXU.US](https://longbridge.com/en/quote/SPXU.US.md) - [SDS.US](https://longbridge.com/en/quote/SDS.US.md) - [SPYI.US](https://longbridge.com/en/quote/SPYI.US.md) - [JEPI.US](https://longbridge.com/en/quote/JEPI.US.md) - [XYLD.US](https://longbridge.com/en/quote/XYLD.US.md) - [AAPW.US](https://longbridge.com/en/quote/AAPW.US.md) - [APLY.US](https://longbridge.com/en/quote/APLY.US.md) - [AAPY.US](https://longbridge.com/en/quote/AAPY.US.md) - [C.US](https://longbridge.com/en/quote/C.US.md) - [GOOGL.US](https://longbridge.com/en/quote/GOOGL.US.md) - [GOOG.US](https://longbridge.com/en/quote/GOOG.US.md) - [TSLA.US](https://longbridge.com/en/quote/TSLA.US.md) - [META.US](https://longbridge.com/en/quote/META.US.md) - [AVGO.US](https://longbridge.com/en/quote/AVGO.US.md) - [NVDA.US](https://longbridge.com/en/quote/NVDA.US.md) - [APO.US](https://longbridge.com/en/quote/APO.US.md) - [MAGS.US](https://longbridge.com/en/quote/MAGS.US.md) - [C-R.US](https://longbridge.com/en/quote/C-R.US.md) - [NVD.DE](https://longbridge.com/en/quote/NVD.DE.md) - [APO-A.US](https://longbridge.com/en/quote/APO-A.US.md) - [APOS.US](https://longbridge.com/en/quote/APOS.US.md) ## Related News & Research - [AI spending gets Microsoft a price target cut, but analyst still says buy](https://longbridge.com/en/news/292808394.md) - [Second iOS 27 and iPadOS 27 Public Betas Now Available](https://longbridge.com/en/news/293504961.md) - [Microsoft Is Deepening Ties with AI Giant Mistral.
