The ETF’s largest holding, Vertiv Holdings, moved after Citi sharply raised its price target on the stock and reiterated a Buy rating, citing robust AI-driven data center demand and expectations for higher long-term organic growth. Howmet Aerospace, another key position, reported first-quarter results and guidance that topped prior expectations, highlighting strong revenue growth, margin expansion, and a boosted full-year sales outlook. Comfort Systems USA also drew attention as its CEO executed a large share sale following strong earnings, record backlog and upbeat guidance, while Cencora’s weight in the portfolio ties JMID to a healthcare distributor that just posted solid profit growth, raised EPS guidance and restarted share buybacks despite trimming its revenue growth outlook. Additional exposure comes from Ross Stores, benefiting from fresh Buy ratings and upside price targets, and Idexx Laboratories, where mixed sentiment reflects concerns over slowing vet visits and leadership changes alongside multiple analyst upgrades and raised long-term earnings targets.
