AI Analysis · Q1 2026

Janus Henderson Group closed Q1 2026 with $209.4B in 13F assets, down from $223.3B, as the manager pared back the very megacaps that anchor its book. NVIDIA (6.88%) remains the largest holding even after a $976M trim, while Microsoft saw the quarter's heaviest cut at roughly $4.1B, followed by Amazon, Oracle and Broadcom. The freed capital flowed toward new positions in AstraZeneca ($2.3B), GE Vernova ($1.3B) and BioAtla, alongside adds in Lam Research, Micron and Johnson & Johnson — a measured rotation away from crowded software toward healthcare, power and semiconductor equipment.

Top of the book. NVIDIA still leads at 6.88% of the portfolio ($14.4B), trailed by Microsoft (4.21%), Apple (3.25%), Alphabet (3.25%) and Amazon (3.19%). The familiar megacap spine is intact — but it is thinner than a quarter ago.

The trims tell the story. Microsoft was cut by roughly $4.1B, the single largest position change, with Amazon (-$1.1B), Oracle (-$1.1B), Broadcom (-$1.0B) and Alphabet (-$896M) close behind. Even NVIDIA, the top holding, was reduced by $976M. Software franchises were exited outright: AppLovin (-$2.2B), Intuit (-$1.3B), Blackstone (-$1.3B), SS&C and Workday all left the book.
