Wittenberg Investment Management, INC.'s disclosed holdings carry a Herfindahl concentration index of 0.073 — mathematically equivalent to about 14 equally-sized positions, well below its 74 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 2.10), 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.
