Strategic stock investing for Wealth Managers and Family Offices.

Wealth preservation is essential. 

But true financial stewardship requires strategic growth—built on conviction, discipline, and risk management.

Many wealth managers and family offices struggle to find stock investment strategies that deliver superior returns without unnecessary complexity. Our approach bridges that gap.

I’m Marcello, a former doctor turned full-time investor with two decades of experience in stock and crypto markets. 

Since 2016, I have worked with wealth managers, family offices, and high-net-worth individuals to implement investment strategies that maximize performance while protecting capital.

In 2020 and 2021, my momentum-based approach transformed $32,000 into over $1 million. 

Today, we refine and apply that strategy for professionals seeking an edge in the markets.

What we offer: 

↳ Institutional-grade stock strategies designed for long-term performance
↳ Risk-managed investment frameworks to navigate uncertainty with confidence
↳ Tailored solutions for wealth managers and family offices seeking scalable, high-conviction strategies

What catches my eye the most in the financial market this early in the year is the array of thriving sectors like gold and other metals, copper, memory, electricity, and so on, whereas the S&P 500 kicked off slowly. Unlike the previous years, I think this will be one where effective stock picking matters more than it has.

I am Sihame.
My name — meaning Arrow in Arabic — was chosen by my parents with intention. The arrow is a symbol of direction, strength, and purpose, and it reflects how I move: with focus, precision, and intent.

Rooted in both Belgium and Morocco, I have spent years navigating complex political, cultural, and business landscapes across the MENA region. 

My work thrives in spaces where trust is earned quietly, influence is built over time, and impact is achieved without noise.
