Manager / firm overview
Headquarters. 200 Clarendon Street, 30th Floor, Boston, MA 02116. Official / public site: www.arrowstreetcapital.com.
Short history. Arrowstreet Capital, Limited Partnership is a Boston-based institutional investment adviser. Public Form ADV materials describe the firm as founded in 1999, organized as a Massachusetts limited partnership, and focused on discretionary equity strategies for institutional clients. A related entity, Arrowstreet Capital Holding LLC (CIK 1402828), appears on the 13F cover as an other included manager.
Peers / commonly compared managers. Factual comparisons only — not invented rivalries:
- Acadian Asset Management
- AQR
- Dimensional Fund Advisors
- other systematic institutional equity managers
Investment model (13F sleeve). The Form 13F shows holdings in thousands of issuers rather than a handful of concentrated bets. Public materials describe long-only equity strategies aimed at beating equity benchmarks, plus other systematic approaches. The latest filing is a 13F combination report: the cover also names other managers (including Russell Investments Group, Ltd. and Columbia Management Investment Advisers, LLC). Treat the dollar total as the filing’s reported table value, not as proof that every line is a single Arrowstreet fund.
Challenges & opportunities. A very wide book makes single-stock stories small versus the total. Opportunities for readers are in sector mix, mega-cap weights, and which names entered or exited — not in treating this like a concentrated activist portfolio.
Recent public / filing update. The canonical Q2 2026 Form 13F-HR (period of report 2026-06-30, filed 2026-08-13) reports about $225.37B across 1,887 table entries. Mapped equity issuers in this view are in the same ballpark as that filing total.
