Custom portfolios built on over 15 years of experience and independent thinking.
Meet AJ Blackstone
Founder · President · Portfolio Architect
For more than 15 years, I’ve been dedicated to building, managing, and refining investment portfolios for individuals, families, and advisors. Over my career, I’ve overseen more than $250 million in client assets, managing hundreds of separate accounts with a focus on precision, discipline, and long-term outcomes.
PortfolioLab exists because I believe investors deserve more than mass-produced models and generic ETF allocations. They deserve a portfolio built for them — engineered with care, grounded in research, and monitored with institutional-level tools.
Experience That Scales
Managing portfolios at scale requires more than investment knowledge — it requires systems, processes, and technology that ensure consistency, accuracy, and transparency across every account.
My background includes:
Designing and managing portfolios across hundreds of separate accounts
Implementing rebalancing systems and workflow automation
Integrated AI-driven research tools to enhance security screening, risk analysis, and portfolio optimization.
Executing trades and maintaining oversight with institutional-level precision
This operational experience is at the heart of PortfolioLab’s approach: customized portfolios built with scalable, repeatable processes.
Investment Philosophy
My investment philosophy is shaped by two timeless schools of thought:
Value Investing — Benjamin Graham
I believe in intrinsic value, margin of safety, and disciplined analysis — principles that remain as relevant today as they were a century ago.
The Mises School of Economics
Strong economic foundations matter. Markets, incentives, and human behavior drive cycles. Understanding the underlying mechanics leads to better decision-making, especially in times of uncertainty.
In practice, this means your portfolio is built with:
Rational expectations
Risk awareness
Independent thinking
A long-term perspective
Never speculation. Never guesswork.
Outside the Lab
When I’m not researching markets or engineering portfolios, you’ll likely find me:
Spending time with my young family,
On the golf course, working on my swing, or
Snow skiing, enjoying fresh mountain air.
