PERFORMANCE HIGHLIGHTS


Top contributors to performance:
↑	AppLovin, in the IT sector, engages in building a software-based platform for advertisers to enhance the marketing and monetization of their content, particularly in mobile apps. AppLovin shares rose on several successive quarter earnings, with sustained growth from the company’s core gaming business and increased optimism around catalyst driven growth in its emerging e-commerce business.
↑	Resideo Technologies, in the industrials sector, is a global leader in smart-home systems and controls including security, HVAC, water, and safety products. The stock rose as opportunities for margin improvement and compounding of revenue growth were augmented by potential separation of two business units to lock sum of the parts value.
↑	Rubrik, in the IT sector, provides data security solutions for individuals and businesses. The company continued to benefit from customers’ increasing prioritization and spending on IT security. Its cloud-based offerings have resonated with its Fortune 500 customer base, positioning it to take shares from legacy data backup providers, while new artificial intelligence (AI) data security products could offer an additional revenue source to Rubrik’s business.


Top detractors from performance:
↓	Alexandria Real Estate Equities, in the real estate sector, is a real estate investment trust (REIT) focused on life science, technology and agricultural technology campuses. The company’s share price fell in response to a dip in occupancy levels and delayed asset sales, as well as concern about demand for lab space by biotech and pharmaceutical companies.
↓	Ultragenyx Pharmaceutical, in the health care sector, is a biotechnology company developing therapeutics to treat rare diseases. The stock came under pressure due to a regulatory rejection for its gene therapy candidate UX111 for Sanfilippo syndrome, a delay of final data for the clinical trial of an important drug development candidate, setrusumab, and questions about the company’s ability to fund ongoing drug development spending in excess of commercial revenue.
↓	Avantor, in the health care sector, is a leading global provider of mission-critical products and services to customers in the biopharma, healthcare, education & government, and advanced technologies & applied materials industries. The company continued to improve its operating margins, but end market trends have been difficult.
