Fred Alger Management, LLC's disclosed holdings carry a Herfindahl concentration index of 0.042 — mathematically equivalent to about 24 equally-sized positions, well below its 525 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 4.20), 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.

FRED ALGER MANAGEMENT is actively rotating capital out of high-flying momentum leaders like MSFT, APP, and META, locking in gains while seeding a new position (add to a 4.37% weight) and initiating a defensive growth toehold in AZN. This is not a retreat from growth but a tactical rebalancing that trades extended mega-cap tech for fresher narratives, still operating within an aggressive momentum framework.
The portfolio's massive overweight to Information Technology (46%) and Communication Services (15%) doubles down on secular digital adoption and AI monetization. The trimming of core mega-cap holdings signals FRED ALGER MANAGEMENT is pricing in a multiple compression regime for the largest tech names, rotating into healthcare and a new high-conviction idea. The opposing thesis holds that tech earnings momentum remains durable, and reducing exposure now risks leaving performance on the table during what could be a continued melt-up.
Despite 444 holdings, the 100 momentum score reveals a portfolio dominated by a single factor — what appears as diversification is actually a liquidity trap where every position is tethered to the same trend. The added 4.37% unknown name concentrates conviction in a stock that is likely a consensus momentum favorite, making the entire book vulnerable to a sharp reversal if that crowded trade unwinds or factor leadership shifts.
