What it bought and sold
We also added Ciena and Lumentum, reflecting rising optical connectivity requirements in AI data centers, and Seagate and Vertiv, which stand to benefit from demand for high-capacity storage and increasingly power- and cooling-intensive data center architectures.

To fund the additions, we exited Roche, Marsh & McLennan and Fair Isaac, positions where our conviction had diminished.
We also added a new position in Ingersoll Rand, a high-quality industrial compounder with recurring aftermarket revenue and exposure to automation, energy efficiency and data center infrastructure.

we initiated a position in Boston Scientific in the health care sector and closed out of Parker- Hannifin in the industrials sector and S&P Global in the financials sector.
we substantially trimmed exposure to Amazon.com and Microsoft.
During the quarter we added to several existing positions in addition to Alphabet: Arista Networks, a leading maker of high-speed switches enabling high-speed data transfer within server racks; Blackstone, an alternative asset manager; and Tesla, an EV and battery storage manufacturer.

we also initiated a position in Micron, a leading memory provider that we believe is well-positioned to benefit from growing AI infrastructure investment as AI data centers require significantly more memory than traditional computing systems.
