What it reported after the quarter end (Q2 2026)

The 13F shows the portfolio as of Jun 30, 2026. Since then Needham Investment Management has filed these own trades with the SEC (Form 4, when it owns more than 10% of a company or holds a role in it) and stakes above 5% (13D and 13G). It is not everything it did: only what it must report before the next 13F.

How we classify it

Type not verified: we have not assigned a type because we found no document that is enough to tell. Most 13F filers are in this situation: we only review in depth those that meet the portfolio criteria.

Not counted as a concentrated manager: its portfolio is not within 5 to 100 positions; its top 10 positions are under 45%. Its portfolio is shown all the same, but it is left out of manager counts, the consensus and the ranking. How this is decided

Managers of a similar size

A 13F portfolio value between a third and three times this one, whatever the type of filer. It is not a comparison of what they hold.
