Compare ESSEX INVESTMENT’s portfolio side by side

See the exact shared positions, conviction overlap, sector alignment, and where these funds diverge — and run the same analysis on any of 8,700+ institutions.

Similarity is derived from each fund’s latest 13F-HR filing with the SEC. Funds are ranked by the overlap of distinctive conviction holdings; near-universal mega-cap positions are excluded so the ranking reflects shared strategy, not common index exposure.
