Why So Few Positions?

State Street consolidates more aggressively in its 13F reporting. While BlackRock reports individual ETF sleeve holdings separately (resulting in 50,000+ lines), State Street groups related holdings. The result: fewer lines, but each carrying substantially more weight.

Average position size comparison among the Big Three:

  • State Street: $695 million per position
  • Vanguard: $390 million per position
  • BlackRock: $118 million per position

AUM Trajectory

State Street has grown steadily from $2.46T in Q3 2024 to $2.98T in Q4 2025 — a 21.3% gain over six quarters. The position count has remained remarkably stable, ranging from 4,260 to 4,297 throughout this period.

What Analysts Might Misread

“State Street is less diversified than peers.” The 4,288 positions still cover virtually every S&P 500 component and thousands of mid-caps. The lower count reflects reporting methodology, not investment scope.

“State Street trails the Big Three.” At $2.98T, State Street is firmly the #3 index manager. The gap to Vanguard ($6.90T) is large, but State Street’s custodian and ETF business extends well beyond 13F-reportable equity assets.
