“If I have seen further than others it is by standing upon the shoulders of giants”.

Isaac Newton

Santiago Investments Advisors was established in early 2015 and is built on a foundation of many decades of combined experiences. The shoulders of giants upon which we stand include investment theory and strategy, technologies which provide access to investment platforms and world-class investment solutions and the greater understanding of the decision-making biases of investors. These developments form the basis of the way we engage and communicate with our clients and of our investment process, producing structures and portfolios that are transparent, robust and liquid.

“The real voyage of discovery lies not in seeing new landscapes but in seeing with new eyes”.
