AlpInvest Partners B.V. Quarterly 13F Holdings Update

AlpInvest Partners B.V.'s disclosed holdings carry a Herfindahl concentration index of 0.137 — mathematically equivalent to about 7 equally-sized positions, well below its 13 actual disclosed holdings. That gap points to a strategy built around a small core of high-conviction bets rather than broad diversification.

Position sizes are fairly uniform across the portfolio (a coefficient of variation of 0.92), suggesting a disciplined, rules-based approach to how much capital goes into each idea.

Recent activity leans toward adding more aggressively to already-large existing positions than to newly initiated ones (a 2.1 percentage-point tilt) — a pattern consistent with a momentum-following approach.

Sector classification currently covers about 42% 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.
