Marshall Wace LLP Rotates From Crowded Mega-Caps To Cyclical AI Plumbing

The biggest buy is SPYM, a broad S&P 500 tracker, effectively swapping some IVV for cheaper, still-liquid beta. That is not a change in macro view so much as a fee and flexibility optimization: maintain market exposure, free up dollars for higher-conviction single-name themes.

Where they are actually pressing risk tells the story:

• SPYM: New at $3.8B and 4.07%, a low-cost index sleeve to keep equity beta on while freeing capital from legacy IVV.
• AAPL: Add of about $437.9M pushes it to 2.28% – they are not abandoning Big Tech, but prefer Apple’s cash machine and ecosystem over more fully-priced cloud and social names.
• ADI / ASML / MRVL / MU / AMAT / APH: Across this cluster, share counts are up sharply (ADI up +40,383.6%, ASML +296.5%, MRVL +116.5%, MU +24.8%, AMAT +3.9%, APH +375.5%). This is a decisive tilt into semiconductors and electronic components – the capex and analog/digital glue that underpins AI, networking and autos.
• CVX and SLB: CVX is up +224.5% (about +$597.6M), SLB up +423.4% (around +$246.4M). Pairing an integrated major with a services name is a classic way to express a sustained energy and capex upcycle view.
• TMUS: Shares up +226.6% (roughly +$345.3M) despite the position sitting below cost (gain_vs_avg_buy_pct -15.8%). That looks like a willingness to average down into a structurally advantaged wireless operator, tying directly into the data and bandwidth side of the AI build-out.
• ABNB, MAR, HLT, CASY, ROST, DG, NFLX: The fund is leaning into travel, hospitality, value retail and streaming. MAR is up +2,183.5%, HLT +29.7%, ABNB +1,310.1%, CASY +354.5%, ROST +36.0%, DG +32.2%, NFLX +197.2%. This is an explicit bet that consumers will keep prioritizing experiences and value over traditional big-box buying.
• MS and COF: MS is up +142.1% (about +$405.4M), COF +23.9%. They are building into credit and capital markets cyclicals, consistent with a view that higher-for-longer rates and active capital markets still have legs.

The common thread: capital is being pulled from crowded winners and redeployed into levered plays on AI infrastructure, energy and late-cycle consumer resilience.

The sells are not random; they are funding sources and crowded trade de-risking.

• IVV: A roughly $4.0B trim (shares -19.0%) is the primary war chest for everything else. They still hold 18.38% in IVV, but the message is: less passive beta, more targeted factor and sector tilts.
• AMZN: Shares are down -26.2% (about -$654.2M). After big gains (up 65.1% vs cost), Marshall Wace is dialing back one of the quintessential mega-cap growth winners and redeploying to areas with more valuation and cyclical torque.
• LLY, JNJ, MRK, UNH: Across big pharma and managed care they are taking chips off the table. LLY is cut -52.3% (roughly -$581.4M), JNJ -35.2%, MRK -30.0%, UNH -17.2%. That’s a broad de-emphasis of defensive healthcare just as they move into more rate- and growth-sensitive plays.
• META, GOOG, GOOGL, MSFT, NVDA, AMD, AVGO, INTC: They are not abandoning AI, but they are clearly trimming the front-page megacaps after huge gains. AMD is still up 262.2% vs cost, INTC 250.8%, NVDA 92.2%. These look like disciplined profit-takes and a rotation from the most crowded beneficiaries to the “picks-and-shovels” tier (ADI, ASML, MRVL, etc.).
• WMT, COST, KO, FIVE: Big-box staples and defensive consumer are being used as cash registers. WMT is cut -76.2% (about -$841.6M), COST -48.5%, KO -47.4%, FIVE -25.3%. The fund is signaling that defensive consumer and staples are no longer where the marginal dollar belongs.
• CRCL: Trimmed -41.9% with the position currently underwater (-31.7% vs cost). That reads as a risk management call on a more speculative fintech/crypto-adjacent name.

Collectively, the trims carve back from stable, crowded, or fully valued exposures and free capital for more cyclical, rate-sensitive and under-owned infrastructure plays.

Sector bars make the tilt explicit. Technology is roughly flat at 28.37%, but the internal mix has shifted: less in mega-cap platforms, more in semis, analog, and components – the boring but essential parts of AI and connectivity.

Consumer Discretionary edges down from 12.04% to 11.24%, but again the mix is the story. They are reducing ecommerce and big-box retail and adding travel, hospitality and value-driven chains – a pivot from stay-at-home and pantry-loading winners to services and price-conscious spend.

Health Care drops from 7.46% to 6.14%, consistent with heavy trims in big pharma and managed care. In their place, Energy jumps from 0.67% to 2.42%, Telecom from 0.32% to 1.03%, and Real Estate from 1.13% to 1.75%.

Finance nudges up from 3.04% to 3.16%, driven by more MS and COF even as CRCL is cut back. Consumer Staples shrinks from 1.68% to 0.88% after the KO reduction. The net effect is a portfolio that is less defensive and less reliant on multiple expansion, and more tied to physical investment, bandwidth, and consumer price sensitivity.

Put together, this looks like Marshall Wace positioning for a regime where nominal growth and capex matter more than duration or pure top-line growth. They are not calling time on AI; they are moving down the stack into chips, materials, connectivity and energy, where earnings are more levered to actual deployment rather than just narrative.

The reduction in healthcare and staples, alongside cuts to WMT, COST and KO, points to a willingness to stomach more cyclical risk. In their place are travel, hospitality and value retail – a bet that the consumer will keep spending, but do so in ways that reward operators with pricing power and experiential pull.

Building MS, COF, CVX, SLB and TMUS while trimming CRCL and some high-flying megacaps also hints at a preference for businesses with tangible cash flows and identifiable operating leverage to rates, spreads and capex. If the next leg of the cycle is about real investment and bandwidth rather than just lower discount rates, this book is aligned with that world.

Investors watching Marshall Wace should not read this 13F as a macro top-down call, but as a rotation within equity risk: less comfort in consensus winners, more exposure to the pipes, power and platforms that must be built if AI and digital demand are to be sustained.
