The concentrated institutional buying from multiple active managers (Bank Of New York Mellon, Citigroup, Walleye entities) suggests a shared thesis around Arteris's semiconductor IP business. However, the absence of insider buying (confluence score 19/100, divergent) tempers conviction — monitor for insider open-market purchases or a catalyst (earnings, design win announcement) to confirm the thesis. The 45-day 13F reporting lag means positions may have been adjusted since quarter-end.
Executive Summary
Seven institutional buyers accumulated $11.8M in Arteris (AIP) during 2026-Q2, led by Bank Of New York Mellon ($3.6M add), Citigroup ($2.5M add), and Walleye Capital ($2.5M add), while only one seller trimmed $495K. The cluster is dominated by active asset managers with three funds more than doubling their positions, signaling conviction in the semiconductor IP thesis.
