Portfolio style

Measured from the filed 13F common-share book for Jun 30, 2026, the newest measured quarter, never from the firm's own description.

Style
Diversified active
Top 10 weight 25.6%, 71.8 effective positions, active share 74.0% against the S&P 500 as of 2026-06-30; it meets none of the index-like, systematic-like or concentrated tests
Turnover
Medium turnover
31.0% over the last four quarters (30% to under 100%)
Horizon
Long horizon
Value-weighted holding period 16.4 quarters (12+), a floor since 41.2% of the book was already held when coverage starts

Closest benchmark: the S&P 500 as of 2026-06-30, active share 74.0%; sector active share 36.2% against the combined 13F book's sector weights.

Over time 26 measured quarters

How the bands are measured

Style bands measure the filed 13F common-share book each closed quarter, tested in this order. Unknown: under $10,000,000 of valued equity or 5 stocks. Index-like (100+ stocks): active share of 20% or less against the closest benchmark, which is the S&P 500, S&P MidCap 400, S&P SmallCap 600, Russell 1000, Russell 2000, Nasdaq-100 or Dow Jones Industrial Average (weighted by an index-tracking fund's reported holdings or the index's constituents nearest the quarter end, over the names resolved to companies, and only when those are 90%+ of its weight) or every 13F filer's combined book, or index series holding 80%+ of the registered fund assets it advises (N-CEN) and equal to 50%+ of its book. Systematic-like: 500+ stocks, 100%+ annual turnover and a top 10 weight of 25% or less. Concentrated: a top 10 weight of 60%+ or 12 or fewer effective positions. Diversified active: none of these. Turnover is the smaller of buys and sells over average equity value, summed over four quarters: low under 30%, high 100%+. Horizon is the value-weighted number of quarters each position has been held: short under 4, long 12+.

Covers the securities this platform tracks: U.S.-listed common stock and the put/call positions reported on it. A 13F can also report security types outside that coverage — preferred shares, bonds, warrants, untracked share classes — so the filing's own declared total can exceed the figures above. The source filing is linked at the top of this table.
