AI Analysis · Q2 2026

American Century Companies ended Q1 2026 at $194.3B across 2,830 holdings, modestly lower than $199.0B. The active manager trimmed nearly every megacap leader — NVIDIA (-$1.2B, still the top holding at 5.48%), Amazon (-$1.1B), Alphabet (-$884M) and Apple (-$678M) — while building new stakes in Intuitive Surgical ($972M), Marsh & McLennan ($734M), Lam Research ($701M) and Micron ($554M). Adds in Vertiv, Costco and Netflix round out a quarter of disciplined profit-taking and selective redeployment.

A megacap-anchored core. NVIDIA leads at 5.48% ($10.6B), followed by Apple (3.29%), Microsoft (3.08%), Amazon (2.60%) and Alphabet (2.59%). The structure is conventional large-cap growth — but the manager spent the quarter taking profits across it.

Trimming winners. NVIDIA was reduced by $1.2B, Amazon by $1.1B, Alphabet by $884M, Apple by $678M and Tesla by $570M. Microsoft saw the largest single change at roughly $1.3B lower. This is the signature of an active book harvesting gains rather than abandoning a thesis.
