Marshall Wace, LLP's disclosed holdings carry a Herfindahl concentration index of 0.060 — mathematically equivalent to about 17 equally-sized positions, well below its 6550 actual disclosed holdings. That gap points to a strategy built around a small core of high-conviction bets rather than broad diversification.
Position sizes vary widely across the portfolio (a coefficient of variation of 12.81), with a handful of outsized bets alongside many smaller positions.
No strong tilt toward either adding to existing winners or initiating outsized new positions was observed in the latest reported quarter.
Sector classification currently covers about 61% of this portfolio's disclosed value; the remainder includes holdings (e.g. unmapped tickers, options, or other security types) not yet covered by our sector mapping.

Institutional Game-State Analysis
Core Intent
The data shows Marshall Wace aggressively scaled up its IVV position from 17.1% to 23.65% of the portfolio, added to MU, COST, ABBV, JPM, and BAC, while trimming NVDA — AMD is also flagged as a trim despite a weight increase, suggesting profit-taking into strength. With 2,748 holdings and a 70.5% turnover ratio, the fund displays classic multi-strategy, high-velocity capital rotation.
Macro & Fundamentals
The flows appear to concentrate exposure in a broad-market index vehicle while rotating into memory semiconductors (MU) and large-cap financials (JPM, BAC); additions in consumer staples (COST) and health care (ABBV) may point toward defensive positioning. This is an inference from a single quarter of data, not a confirmed call on macro direction.
Blind Spots / Risks
A coefficient of variation at 12.8 and a zero position-sizing discipline score reveal a portfolio where the vast majority of the 2,748 names carry negligible weight — the real risk may be the unglamorous tail, where illiquid micro-positions could become disproportionately hard to unwind precisely when the crowded index and semiconductor trades face a liquidity squeeze simultaneously.
