Thrive Capital Management, LLC — 13F Filings Deep Dive

Thrive Capital Management, LLC's disclosed holdings carry a Herfindahl concentration index of 0.257 — mathematically equivalent to about 4 equally-sized positions, close to its 5 actual disclosed holdings. Value is spread relatively evenly across the portfolio rather than concentrated in a handful of names.

Position sizes are fairly uniform across the portfolio (a coefficient of variation of 0.59), suggesting a disciplined, rules-based approach to how much capital goes into each idea.

Recent activity leans toward initiating meaningfully larger new positions than it adds to existing ones (a 30.9 percentage-point tilt) — a pattern consistent with a more contrarian, new-idea-driven approach.
