Where conviction is rising: S&P beta, banks, and real-economy cash flows
The biggest buy is IVV, with an estimated $10.14B added, cementing the S&P 500 as the portfolio’s anchor. That’s not closet indexing; it’s a funding choice that lets them own the equity market while they actively rotate the satellite positions around it.
Beyond the index, the capital flow is clear: they want scalable, fee‑rich financials and durable cash‑flow franchises.
- COST: share count up 345.3%, roughly $852.0M added, signaling a full embrace of Costco as a volume‑driven, membership‑moat consumer staple in disguise.
- ABBV: effectively built from scratch (shares up 281,757.9%) into a $752.5M line, a strong statement that large‑cap pharma still offers mispriced pipelines and cash flows.
- JPM and BAC: JP Morgan’s stake grows by 11,481.2% and Bank of America by 581.8%, adding about $641.9M and $607.0M respectively; that’s a coordinated bet on scale banks as beneficiaries of higher-for-longer rates and resilient credit.
- MU and QCOM: Micron (+49.6% shares, +$516.3M) and Qualcomm (+10,156.6% shares, +$454.2M) show that within semis, Marshall Wace is leaning into memory and connectivity, not just GPU headlines.
- AXP and CME: American Express (+1,033.9%) and CME (+178.7%) are being treated as structural payment and volatility tollbooths, extending the financial-infrastructure theme.
Secondary but telling are big add-ons to IBM, TXN, CSCO, NOK, ADP, UPS, PH, KO, MNST, HOOD, and UBER. The pattern is consistent: real-economy rails, services, and brand moats with credible pricing power, bought in size while the market debates how late the cycle is.

What they’re selling: harvesting elite AI and rich winners to pay for breadth
If the buys show what Marshall Wace wants to own, the trims show what they think has done its job. The largest dollar reductions are a who’s‑who of AI and semiconductor leaders — not abandoned, but resized from return engines to funding sources.
- NVDA: shares cut by 36.8%, freeing about $1.01B while still keeping a 1.46% portfolio stake; this looks like disciplined profit‑taking in a name up 92.2% versus their average cost.
- SNDK, INTC, AVGO, AMAT: SanDisk (-62.9%), Intel (-65.6%), Broadcom (-52.0%), and Applied Materials (-48.2%) collectively release several billion of estimated capital. They are rotating out of the most crowded, multiple‑rich or fully‑discounted parts of the silicon stack.
- GOOGL, META, MSFT: Alphabet (-30.2%), Meta (-7.9%), and a small trim in Microsoft (-0.9%) show a cooling of pure mega‑cap growth exposure at the margin, especially where gains versus cost are already large.
- LLY: Eli Lilly is cut 41.9%, taking profits in a GLP‑1 poster child while simultaneously scaling up other pharma like ABBV, ABT, JNJ, and UNH.
- CVX and TMUS: Chevron (-39.3%) and T‑Mobile (-10.5%) are bled down, signaling that integrated oil and U.S. wireless are less central to the medium‑term thesis than banks, semis, and diversified healthcare.
Notably, these are trims from strength: gain_vs_avg_buy_pct is comfortably positive across the big tech, semi, and pharma reductions. They’re not capitulating; they’re cashing winning lottery tickets to buy cash machines.
Sector map: tech de‑risked, financials and defensives step up
On a sector level, Marshall Wace is pulling the throttle back on pure tech and redeploying into financials, healthcare, and old‑economy infrastructure. Technology falls from an estimated 32.85% to 23.29% of the portfolio, even as they add heavily to selected names like MU, QCOM, IBM, TXN, CSCO, and NOK.
The real climbers are the financials. Finance jumps from 2.48% to 5.38%, driven by the aggressive builds in MS, BAC, JPM, CME, AXP, and HOOD. That’s a big swing for one quarter in a sector whose earnings power tracks rates, market volumes, and consumer health.
Healthcare edges up from 4.42% to 5.21%, but the mix changes: capital is rotating from momentum‑charged LLY into a basket of diversified pharma and managed care (ABBV, ABT, JNJ, UNH, plus MO via its pseudo‑defensive cash yield). Consumer staples climb from 1.06% to 1.61%, led by KO and MNST, complementing the quasi‑staple COST sitting in consumer discretionary.
Industrials (3.03% to 3.58%) and telecommunications (0.85% to 1.14%) rise via ADP, UPS, PH, CSCO, and increased NOK, reinforcing the “picks and shovels” theme in logistics and networks. Energy, interestingly, is roughly flat at 1.97% despite a huge add to XOM offset by a sharp CVX cut — this is position‑level optimization, not a top‑down oil call.
Overlaying all of this is the giant IVV position, lumped into “Unclassified” at 49.96% from 45.9%. Functionally, that is S&P exposure: sector‑balanced market beta underwriting an increasingly barbell‑shaped set of active tilts.
Reading the playbook: what this quarter implies from here
Taken together, the 2026 Q2 13F says Marshall Wace is less interested in squeezing the last dollar out of AI leaders and more interested in owning the durable economics that will persist once the hype fades. They are using the S&P 500 as a chassis and bolting on high‑conviction overweights in banks, semis, telecom gear, logistics, and big‑cap healthcare.
The internal rotation within technology is particularly telling. Capital is flowing from GPU‑centric narratives (NVDA, AVGO, AMAT, INTC) toward memory (MU), connectivity (QCOM, NOK, CSCO), and legacy tech with cash‑return angles (IBM, TXN, CRM). That reads as a belief that the AI capex cycle is real, but that the best risk‑reward now lies in the broader supply chain and infrastructure, not just the marquee chip names.
At the same time, the aggressive rebuild in JPM, BAC, AXP, CME, and MS suggests they see cyclical fear in financials as overdone. If credit stays contained and rate cuts are measured, these names can compound on volumes, spreads, and fee income without needing heroic growth assumptions.
The modest but deliberate increase in healthcare and staples, plus upgrades to COST, KO, MNST, and defensive pharmas, rounds out the picture: they’re preparing for late‑cycle chop with businesses that can raise prices and keep customers. This is a portfolio re‑engineered for resilience — willing to sacrifice some upside beta for a steadier stream of earnings power tied to real economic activity.
For investors tracking Marshall Wace, the takeaway isn’t a hot stock tip; it’s the template. When a high‑octane stock‑picker who has run at 22.65% annualized over three years starts swapping pure growth for market beta plus cash‑flow moats, it’s a clear signal about where they think the easy money has already been made.

Marshall Wace’s largest disclosed holding as of 2026 Q2 is IVV, the iShares S&P 500 ETF, at 25.17% of the reported equity portfolio. The second-largest single stock positions are blue-chip tech names like Apple, Amazon, and AMD, each under 2.5% of the book.
How is Marshall Wace LLP changing its technology exposure?+
Marshall Wace reduced overall technology weight from an estimated 32.85% to 23.29%, trimming high‑flyers like Nvidia, Broadcom, Applied Materials, Intel, Alphabet, and Eli Lilly (in healthcare) to fund bigger stakes in Micron, Qualcomm, IBM, Texas Instruments, Cisco, and Nokia. They are shifting from concentrated AI and mega‑cap growth toward a broader mix of semis, connectivity, and legacy cash‑flow tech.
Which sectors is Marshall Wace LLP favoring after 2026-Q2?+
After 2026 Q2, Marshall Wace is clearly favoring financials, healthcare, and consumer defensives on top of its large S&P 500 core. Finance jumped to 5.38% of the book, healthcare to 5.21%, and consumer staples to 1.61%, while technology still remains the single largest active sector exposure despite being trimmed.
Did Marshall Wace LLP reduce its NVIDIA position in 2026-Q2?+
Yes. Marshall Wace cut its Nvidia stake by 36.8% in share terms, realizing an estimated $1.01B in gains versus their average cost, but they still hold Nvidia at 1.46% of the portfolio. This looks like disciplined profit‑taking rather than a full exit.
Is Marshall Wace LLP becoming more of an index investor?+
The firm isn’t abandoning stock‑picking, but its 2026 Q2 moves show a clear decision to run a very large S&P 500 core via IVV while expressing views at the margin in sectors like banks, semis, telecom equipment, logistics, and big‑cap healthcare. It’s closer to a barbell of market beta plus concentrated thematic tilts than to pure active stock‑picking.
