Portfolio Update — April 27, 2026
This paper presents a final 50-name P3 US Growth Portfolio watchlist, grouped by theme and summarized with each company’s core strength and the reason it belongs in a durable-growth portfolio built for what I describe as an Age of Austerity. Portfolio 3, after it goes live, will contain a maximum of ten of these 50 stocks. The objective is not to maximize aggressiveness. It is to identify US companies with durable demand, strong or improving free-cash-flow characteristics, healthy margins, and business models that can withstand a more difficult macro backdrop than the one that followed the Covid-19 recovery. Each company has a superior Ziggma score for the fundamentals I consider important for this portfolio.
Several trade-offs shape a list like this. Sector and industry diversification matter, as does market capitalization, but the primary focus is on business durability, revenue quality, pricing power, and the capacity to compound earnings and free cash flow through a tighter cycle. Consumer spending is expected to be under pressure, so the emphasis is placed on structural demand, mission-critical products and services, and operating models that should be more resilient than high-beta cyclical growth stories.
Financials are not a primary hunting ground for growth in this framework. Where financial-related names appear, they are included because they have specialized niches, recurring revenue, counter-cyclical characteristics, or unusually strong compounding features relative to the broader sector.
AI, semiconductors, and infrastructure hardware
· Strength: High-performance CPUs and GPUs tied to AI, cloud, and edge computing.
· Why it made the list: Structural compute demand should keep growing faster than GDP, and capital tends to flow toward architectures that improve performance per watt and per dollar in constrained spending environments.
· Strength: High-performance switching, routing, and networking software for hyperscale cloud and large enterprises.
· Why it made the list: AI data centers require high-bandwidth, low-latency networking even when broader IT budgets tighten, and Arista benefits from strong margins, cloud relevance, and durable platform positioning.
· Strength: Diversified semiconductor and infrastructure software franchise with exposure to networking, custom silicon, and mission-critical enterprise systems.
· Why it made the list: Long customer relationships, high margins, and infrastructure-level relevance provide resilience, while AI and networking remain secular growth drivers.
· Strength: Process control and inspection tools essential to semiconductor manufacturing.
· Why it made the list: Yield management becomes more critical as chip complexity rises, so fabs continue to fund process control even when wafer-fab spending is disciplined; that supports durable growth and strong cash generation.
· Strength: Low-power FPGAs serving industrial, communications, and edge applications.
· Why it made the list: Intelligent edge and power-efficient control remain attractive in a capital-scarce environment, and Lattice combines this with high gross margins and an asset-light model.

· Strength: Observability and cloud monitoring platform spanning infrastructure, logs, security, and developer workflows.
· Why it made the list: Datadog reported 2025 revenue growth of 28%, operating cash flow of $1.05 billion, and free cash flow of $914.7 million, while guiding 2026 revenue to $4.06 billion to $4.10 billion, which supports the case for durable, high-margin, cash-generative growth despite valuation sensitivity.
· Strength: E-signature and agreement-workflow platform with a large installed base.
