Fred Alger Management

Day-to-day portfolio decisions rest with a team of dedicated portfolio managers, each overseeing a specific strategy. Brandon Geisler leads the Mid Cap Growth portfolio and has publicly shaped the firm's thematic views around AI-driven demand. The firm emphasizes a collaborative research culture where bottom-up stock ideas are vetted across the analyst and PM ranks.

Alger defines Positive Dynamic Change as a catalyst that creates a significant inflection in a company's growth trajectory. The framework screens for innovation, regulatory shifts, or new leadership that can drive sustained earnings acceleration. Rather than buying stable growth at any price, the team targets the overlooked acceleration phase — the moment when change is underappreciated by the market.

Alger is a regulated, SEC-registered asset manager, not a family office. The firm manages pooled vehicles including mutual funds and ETFs alongside institutional separate accounts and SMAs. Its ownership structure — 100% women-owned — differentiates it from most publicly traded or private-equity-backed asset managers.

The firm's primary strategies are US equities focused, though it operates a Tokyo office and offers UCITS vehicles for European investors. Alger's research process evaluates global companies where Positive Dynamic Change is identifiable, but most mandates are benchmarked to US equity indices. Allocators seeking dedicated ex-US strategies should confirm current product availability.

HALO stands for High Active-Loyalty Ownership — companies where management and insiders demonstrate significant, sustained equity ownership alongside shareholders. Alger views high insider alignment as a signal of conviction and long-term strategy execution. The concept is integrated into the firm's proprietary research rather than applied as a standalone screen.
