PERFORMANCE HIGHLIGHTS


Top contributors to performance:
↑	AppLovin, a mobile technology company that engages in building a software-based platform for advertisers to enhance the marketing and monetization of their content within the IT sector, saw its software segment continue to grow, powered by its proprietary targeting software platform that has incorporated artificial intelligence (AI) capabilities.
↑	Marvell Technology, a networking and storage semiconductor company in the 5G, data center, and automotive ethernet end markets within the IT sector, had its share price rally on the back of greater AI enthusiasm from investors and the potential long-term growth afforded by greater demand for data and data centers.
↑	Vertiv, a global manufacturer of power, precision cooling and infrastructure management systems for mainframe computer, server racks and critical process systems within the industrials sector, saw strong data center demand and enthusiasm for AI-related technology.


Top detractors from performance:
↓	Freshworks, a software development company that provides modern software-as-a-service products including customer service, operations and customer relationship management applications within the IT sector, had its share price decline during the period as investors began to worry that Freshworks was no longer an AI beneficiary.
↓	Five Below, a specialty value retailer within the consumer discretionary sector, had its share price impacted by elevated shrink, as well as persistent inflationary pressures weighing on lower-end consumers. Declining sales, elevated shrink and the departure of the company’s CEO ultimately contributed to the security not being held at period-end.
↓	Aptiv, a Tier 1 automotive parts supplier to global automakers within the consumer discretionary sector, faced pressure stemming from the United Auto Workers strike in 2023, along with headwinds to the broader auto cycle and a slowing in electric vehicle adoption that weighed on margins (not held at period-end).
