I’m focusing on the big AI infrastructure players

In seeking to capitalize on artificial intelligence (AI), Matt Fruhan is emphasizing the largest players while maintaining flexibility to adapt as market conditions evolve.

  • As AI continues to attract capital and investor attention, Fidelity Portfolio Manager Matt Fruhan is favoring big companies that he believes are well-positioned to navigate the supply-constrained and increasingly expensive landscape for the fast-growing technology.
  • “In the recent narrow market environment, my strategy has been to overweight infrastructure-related companies and others developing data centers and the broader AI ‘backbone,’” says Fruhan, who manages Fidelity Advisor® Large Cap Stock Fund. “These businesses have benefited from strong demand, which has contributed to supply bottlenecks and pricing power that has supported earnings growth.”
  • In leading the diversified domestic equity strategy, Fruhan focuses on large-cap stocks that he considers mispriced due to investors’ overreaction to changes in short-term earnings estimates. He believes that combining thorough research with patience and discipline can help investors capitalize on these pricing inefficiencies.
  • Fruhan’s approach to choosing stocks is largely based on his estimate of a company’s earnings potential over the next three to five years, though he acknowledges that forecasting can be more challenging with an emerging technology such as AI.
  • With this in mind, he is looking across sectors and emphasizing large companies with leading market positions and scale. He views these firms as better positioned to invest in increasingly costly AI tools, helping to lower costs while leveraging their extensive proprietary data to gain market share or develop value-creating products.
  • “I believe large companies adopting AI may have a competitive advantage, and I have positioned the fund accordingly, with select mega-cap holdings in financials, aerospace, energy and health care,” he says. 
  • Within AI infrastructure, he cites AI-focused chipmaker Nvidia and Google parent Alphabet, two of the fund’s top holdings as of August 31. Nvidia has benefited from soaring demand for AI chips, he notes, while Alphabet has gained as investors have become increasingly optimistic about its competitive position in AI, both through its chip business and its development of large language models.
  • Looking ahead, Fruhan believes the AI landscape will remain highly dynamic, with companies viewed as “winners” and “losers” potentially changing multiple times in the years ahead as technologies evolve.
  • Many questions about AI remain, according to Fruhan, as investors continue to debate the direction and sustainability of the technology. “Are we already at a cyclical peak in earnings? Or are we in the middle of a long-term growth cycle?” Fruhan asks, noting that investors with high conviction about where the market is headed may be fooling themselves.
  • “I plan to continue monitoring the market environment and gradually adjusting my AI investment strategy as conditions warrant,” Fruhan concludes. “Fundamental research is the bedrock of my approach, and I seek to capitalize on shifts in sentiment, particularly when investors grow anxious about AI or the duration of the capital investment cycle, as well as when enthusiasm leads to indiscriminate buying of AI-related stocks.”

Sector funds can be more volatile because of their narrow concentration in a specific industry. Growth stocks can perform differently from other types of stocks and the market as a whole and can be more volatile than other types of stocks. Value stocks can perform differently than other types of stocks and can continue to be undervalued by the market for long periods of time. • Stock markets, especially foreign markets, are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. • Foreign securities are subject to interest rate, currency exchange rate, economic, and political risks, all of which are magnified in emerging markets. • In general the bond market is volatile, and fixed income securities carry interest rate risk. (As interest rates rise, bond prices usually fall, and vice versa. This effect is usually more pronounced for longer-term securities.) Fixed income securities also carry inflation, credit, and default risks for both issuers and counterparties. • Lower-quality bonds can be more volatile and have greater risk of default than higher-quality bonds. • Floating-rate loans may not be fully collateralized and therefore may decline significantly in value. • The municipal market is volatile and can be significantly affected by adverse tax, legislative, or political changes, and the financial condition of the issuers of municipal securities. • The securities of smaller, less well-known companies can be more volatile than those of larger companies. • The funds can invest in securities that may have a leveraging effect (such as derivatives and forward-settling securities) that may increase market exposure, magnify investment risks, and cause losses to be realized more quickly. • Leverage can magnify the impact of adverse issuer, political, regulatory, market, or economic developments on a company. In the event of bankruptcy, a company’s creditors take precedence over the company’s stockholders. Although the companies that the fund invests in may be highly leveraged, the fund itself does not use leverage as an investment strategy. Changes in real estate values or economic downturns can have a significant negative effect on issuers in the real estate industry. In the event of bankruptcy, a company’s creditors take precedence over the company’s stockholders.
