AI Analysis · Q4 2025

Last quarter Super Micro Computer was nearly a tenth of Needham Investment Management's book at about $67.4 million (9.1% of $742 million). This quarter SMCI is still held (~$40.4 million) but only 2.6% of a portfolio that more than doubled to $1.58 billion—weight collapsed mostly on price, not a massive share dump. The new posture is a flatter specialty-tech roster led by nLIGHT (4.4%), brand-new Vicor (3.9%), and new PDF Solutions (3.5%), with twenty-seven opens and twenty-seven exits expanding a 322-name growth-and-tech sleeve.

Last quarter Super Micro Computer was Needham Investment Management's defining weight—about 1.41 million shares and $67.4 million, 9.1% of a $742 million book. Vertiv was 5.8%; Nova Ltd about 5.0%. Concentration in AI-adjacent hardware was the posture.

This quarter the same firm reports $1.58 billion across 322 holdings. SMCI is still there at 1.38 million shares and $40.4 million, but only 2.6% of the enlarged book. Share count barely moved (about −1.8%, roughly $0.7 million of share-flow selling); the ~$27 million drop in position value is almost entirely mark-to-market. The flagship did not get sold out—it got diluted by size, price, and a flood of new peers.
