Factors Affecting Performance [Text Block]

What drove fund performance during the past 12 months?

Science and technology stocks advanced during the period as corporate earnings remained favorable, investors favored artificial intelligence (AI)-related businesses and other high-growth companies, and Congress passed tax legislation that should provide some fiscal stimulus to the economy.
Internet company Alphabet and semiconductor company Broadcom were top absolute contributors in 2025. Alphabet advanced on explosive growth in its Gemini AI platform, Google Search and AI Overviews expansion, and a favorable antitrust ruling late in the period that allowed Google to retain key search distribution deals. Broadcom benefited from sector-wide AI adoption as its applications-specific integrated circuits, marketed as “XPUs,” gained significant traction among hyperscale companies seeking energy-efficient alternatives in the market.
Software companies ServiceNow and Salesforce detracted on an absolute basis. ServiceNow declined on concerns regarding the company’s slowing subscription revenue growth and mixed reception on its late-period acquisition of Armis, which investors viewed as expensive and a complex integration. Shares of Salesforce fell due to slow adoption of its Agentforce AI platform, heavy AI investments, and competitive pressure from sector peers.
The fund seeks to provide long-term capital appreciation and focuses on technology companies with potential for real earnings and revenue growth and a leading or growing market share. We remain focused on investing in science and technology companies that we believe are on the right side of change, the right side of the numbers, and the right side of macroeconomic trends.
