Hedge fund allocation and liquid alternatives, custom-built for one client at a time.
My approach is defined by a clear hierarchy of priorities: the client comes first, the portfolio allocation second, and the manager selection third.
I assist sophisticated investors in evaluating hedge funds and liquid alternatives, selecting managers, and constructing portfolios tailored to their specific objectives, liquidity needs, and existing exposures.
**Client First:**
We begin by defining your objectives, constraints, and total portfolio structure.
**Allocation Second:**
We size, combine, and implement strategies with a disciplined focus on risk and liquidity.
**Manager Third:**
We select the specific managers best qualified to fulfill those defined roles.
Why Mario
An allocator’s perspective, strengthened by experience running risk.My background combines portfolio construction, manager evaluation, and institutional trading. I have worked on both sides of the decision: assessing managers as an allocator while also managing and trading strategies myself.
- Portfolio experience: USD 1.2B across 20 vehicles. At a Spanish institution, I gained hands-on experience co-managing day-to-day operations of approximately USD 3 billion across alternative investment vehicles, with a focus on hedge-fund portfolio construction, manager evaluation, and quantitative analysis.
- Institutional experience: I designed and managed a global multi-asset strategy, advising key decision makers on portfolio allocation and alternative investments.
- Current practice: Through Sizemore Capital, my work spans multi-asset and fund-of-funds implementation, manager due diligence, and the ongoing monitoring of systematic and quantitative strategies.
- Manager perspective: My trading and quantitative background helps me look beneath headline performance to understand how strategies actually generate returns, where risks can reside, and how they may behave in different market environments.

Philosophy
The right alternative investment starts with the client and the portfolio — not with a fund.
The allocation comes first; the manager follows.
Are you evaluating hedge funds, liquid alternatives, or the role of alternative investments within a broader portfolio?
Let’s begin with a confidential conversation about your objectives and the role you want alternatives to play.
