East Coast Asset Management, LLC.'s disclosed holdings carry a Herfindahl concentration index of 0.096 — mathematically equivalent to about 10 equally-sized positions, well below its 81 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 2.61), with a handful of outsized bets alongside many smaller positions.
Recent activity leans toward adding more aggressively to already-large existing positions than to newly initiated ones (a 3.9 percentage-point tilt) — a pattern consistent with a momentum-following approach.
