Born in Madrid in 1968, Marcos Hernández Aguado holds a degree in Economics and Business Administration from Universidad Pontificia Comillas (ICADE E-2) and is a Qualified Financial Analyst, accredited by the UK Financial Services Authority.

He has over 30 years of experience in listed equities, including 15 years as a sell-side and buy-side financial analyst across a wide range of sectors, followed by extensive experience as a value-oriented fund manager. His investment approach is inspired by the long-term, fundamentals-driven value philosophy of Warren Buffett and Charlie Munger, with a focus on business quality, capital discipline, and downside protection.

Marcos began his career at Crédit Agricole in Madrid and later worked at Merrill Lynch in London, gaining international exposure to equity research and capital markets. He joined SIA Asset Management in 2008 as a Senior Analyst, where he progressively assumed greater responsibilities, becoming Head of Research, Co-Manager of the funds, and, in 2019, Portfolio Manager. He currently serves as Managing Partner and Chief Investment Officer (CIO) of SIA AM.

His strategic objective is to position SIA AM as a trusted long-term partner for both investors and portfolio holdings. His investment process emphasizes capital preservation and decent returns, in line with Keynes’ principles of investment, targeting average annual net returns of 10–12% while maintaining a very low risk profile.

Marcos’ professional approach is guided by seriousness, discipline, transparency, and a strict quality value philosophy, combined with strategic long-term thinking and a highly disciplined circle of competence.
