Regulatory profile

From Form ADV, the SEC filer profile, 13D/13G type codes and N-CEN, never from the name.

Schedule 13G, Jan 12, 2024

Schedule 13D/13G stakes

Stakes of 5% or more disclosed on Schedule 13D or 13G, each on the filer's latest filing for the security. These are event-dated stakes, not the quarter-end 13F portfolio below.

Company Schedule Filed Shares % of class Status
CNDB now GCTS GCT Semiconductor Holding, Inc. 13G 2y 375,000 9.51% Unconfirmed since Nov 1, 2023

A 13D or 13G stays in force until its filer amends it and no amendment is due without a material change, so a stake with no filing in 24 months reads unconfirmed, never sold. An amendment reporting under 5% ends the filer's duty to amend, not necessarily the holding. Shares are restated onto today's split basis. Show 7 exited, below-5% or retired stakes

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.
