Vestiio consistency score

Vestiio follows each manager’s 13F filings from the day they became public and scores how the disclosed positions went on to do against other managers filing for the same quarter. Beating the field repeatedly, over up to five years, counts for more than one strong quarter. The top of the latest ranking scores 66.0.

Both figures estimate the reported equity book, followed from the day each filing became public. They do not measure the fund’s actual returns: a 13F leaves out cash, short positions, private holdings and everything traded between filings.

Ranking of 16 September 2026. On average 95% of the reported book mapped to priced securities in the quarters counted. Confidence: high.

Latest reported holdings

324 positions worth $169.1 billion for the quarter ending 30 June 2026. The ten largest make up 42.6% of the book.

How the score works

The consistency score takes the positions each 13F reports, weighted by their share of the book, and measures how they performed over the 90 days after the filing became public. It then compares that result with every other eligible manager’s filing for the same quarter, and rewards beating them repeatedly more than one strong quarter.

  • Up to 20 completed quarters count. A manager is ranked once it has at least twelve, with an average of at least 80% of the book priced across them.
  • A quarter counts when at least 70% of its book maps to listed securities with daily prices, and when at least 20 managers have a completed quarter to compare.
  • At least a quarter of the book must sit in its ten largest positions, because a book spread across thousands of names describes the market more than the manager.
  • Options, exchange-traded funds and other funds stay in the holdings table and are left out of the score.
  • When a filing is restated, the restatement replaces the original, so each quarter counts once.
  • Operating companies, sovereign funds, pensions, venture capital firms, private equity sponsors and banks are not ranked.

The one-year figure compounds the last four completed 90-day windows. A filing counts once its window has closed, so a new filing moves neither number on the day it arrives.

The full method, with the weights and a worked example

Source: SEC Form 13F filings by Primecap Management (CIK 763212). Holdings as filed for the quarter ending 30 June 2026, valued as reported; returns use daily closing prices. The ranking of 16 September 2026 covers 978 managers.
