AIHC Capital Management Ltd SEC 13F Disclosure Analysis

AIHC Capital Management Ltd's disclosed holdings carry a Herfindahl concentration index of 0.524 — mathematically equivalent to about 2 equally-sized positions, well below its 5 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 1.42), with a handful of outsized bets alongside many smaller positions.

Recent activity leans toward initiating meaningfully larger new positions than it adds to existing ones (a 24.5 percentage-point tilt) — a pattern consistent with a more contrarian, new-idea-driven approach.

Sector classification currently covers about 67% 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.
