Who we are

We are fund managers

Cartesio is a fully regulated Sociedad Gestora de Instituciones de Inversión Colectiva (SGIIC) registered with the Spanish National Securities Market Commission (CNMV).

En 2004 tres socios fundaron Cartesio con una visión clara: gestionar inversiones de manera sencilla, transparente y hacerlo con incentivos distintos a los de la industria. El primer patrimonio que gestionamos fue el nuestro, marcando un compromiso personal que sigue vigente. Hasta hoy, más de 5.000 clientes se han sumado a Cartesio para convertirnos en una de las principales gestoras independientes de España.

Over the years, we have evolved from a founding team to a shared management company. Since 2019, the shareholder base has expanded, integrating all members of the investment management team and key employees as partners, reinforcing our collective commitment.
Since its inception, Cartesio has managed only two funds. Additionally, Cartesio offers the possibility to invest in two Luxembourg-domiciled funds (Cartesio Income and Cartesio Equity) that replicate the strategy of the two funds registered in Spain.

Why choose us

Our incentives

We invest all our financial assets in the funds that we manage

The fund managers of Cartesio are committed to investing all their financial assets savings in the Cartesio funds, as reflected in Cartesio's Internal Code of Conduct. Since the launch of the funds in 2004, the founding partners of Cartesio have remained as managers, and three new partners who are part of the management team have joined them.

Only two funds

We intentionally have only two management strategies, which allows us to concentrate the management team's efforts on improving when a fund does not perform as expected, instead of closing the fund or launching a new one. This guarantees a dedicated and transparent approach. By combining both funds, clients can choose a suitable level of risk for their investment portfolio.

Capital protection and risk management

The funds are managed with the objective of outperforming the risk-adjusted returns of European equities (Cartesio Y) and long-term eurozone government debt (Cartesio X). To achieve this objective, we try to minimize losses and recover them in the shortest possible time. Investments are based on fundamental research and long-term thinking, avoiding short-term strategies.

Low management fees, both fixed and performance

We have lower fees than the market average among active management funds that combine a fixed and performance related management fee. The high-water mark guarantees a fair performance fee. That is, in case of losses, a performance fee is not charged again until those losses are recovered. If five years pass without positive returns, a new high-water mark will be established.

Active management

High flexibility in asset allocation. We seek to adapt the funds to market opportunities and risks. Stock selection differs considerably from the fund's benchmark index, a high “active share” is key when considering ourselves active managers. We believe that cash is another asset that protects capital and allows portfolios to react quickly to changes in the market.

Transparency

We publish a monthly management report for each fund, pioneering and exemplary in the market. It details the portfolio composition, performance, and volatility both in absolute terms and in relation to the benchmark index for the fund. Additionally, it includes commentary on the factors that have influenced the fund's performance and future strategy.
