Assetmark, Inc's disclosed holdings carry a Herfindahl concentration index of 0.014 — mathematically equivalent to about 73 equally-sized positions, well below its 3558 actual disclosed holdings. That gap points to a strategy built around a small core of high-conviction bets rather than broad diversification.
Position sizes vary widely across the portfolio (a coefficient of variation of 6.89), with a handful of outsized bets alongside many smaller positions.
No strong tilt toward either adding to existing winners or initiating outsized new positions was observed in the latest reported quarter.
Sector classification currently covers about 35% of this portfolio's disclosed value; the remainder includes holdings (e.g. unmapped tickers, options, or other security types) not yet covered by our sector mapping.

The quarter reads as a measured net-add cycle rather than a directional bet: seven of the eight largest moves were adds, clustered in broad-market index vehicles (VOO, IVV, MGK, MGV, VBR) alongside mega-cap tech (NVDA, GOOGL), with Micron the lone trim. With 3,558 positions, an HHI of just 0.014, and a 23.6% turnover ratio, the footprint appears consistent with an aggregated advisory-platform book — flows into passive cores rather than concentrated stock-picking conviction. Two price-versus-action divergences stand out: MU was actively trimmed yet its weight nearly tripled (0.26% to 0.69%) as price outran the selling, while MGV was added but slipped to 4.45%; share-count magnitudes are undisclosed, so scale can only be read directionally.
These flows appear to line up with the prevailing large-cap growth / AI-infrastructure bid — IT sits near 34% of the book, Communication Services another 13.4%, and both NVDA and GOOGL drew adds — while the VBR add hints at early breadth extension beyond mega-caps. That said, this is an inference from a single quarter of positioning data covering only about 35% of mapped value; it suggests alignment with the trend rather than confirming any causal driver.
The most concrete data risk is coverage: only ~35% of reported value maps to classified holdings, meaning conclusions rest on a minority slice of a 3,558-line file, and the unmapped remainder could carry materially different exposures than the visible top of the book. Layered on top, a 95.95 momentum score against a ~34% IT sleeve leaves the aggregate book structurally long the market's most crowded trade — a positioning squeeze out of AI-linked names would find little offset elsewhere in the portfolio.
