In the first quarter of 2026, Class A shares of the Alger Mid Cap Focus Fund underperformed the Russell Midcap Growth Index in a volatile market environment. The Communication Services and Industrials sectors contributed to the fund’s performance while Health Care and Consumer Staples detracted. Two major influences changed the investing environment in the quarter. The software industry experienced significant disruption due to the rise of agentic artificial intelligence tools, whereas the U.S.-Iran conflict that began in late February sent the oil prices more than $100 per barrel for the first time in four years. The Fund identifies opportunities for companies that are adopting and facilitating the technology as it evolves into an agentic phase, despite the market’s focus on industries affected by AI advancements.
