About Orthos Advisory
Orthos Advisory AG is a registered investment advisor that operates in three distinct modalities:

A. Management - classic discretionary investment management services with two strategies:
  1. Orthos Classic Strategy
  2. Orthos Enterprising Strategy
B. Advisory - non-discretionary investment management service

C. Consulting - supervision of overall investment programs

    We operate in a fully independent manner, and receive all of our revenues from our clients, thereby maintaining full objectivity in selecting investment strategies and vehicles for implementation.

    We strive to operate on a profitable basis and in complete partnership with our clients. This means that we shall periodically review our fee structure and will adjust it in relation to the volume and size of our business. In essence, the advantages of scale will be shared with our clients.

    Guiding Principles
    In medicine the fundamental aims are to improve the overall health of people, to help them avoid getting sick and to cure their illnesses. Similarly, in financial management the aims are selecting the proper investment strategy (improve overall health), eliminate unnecessary costs (avoiding getting sick) and reacting promptly if circumstances warrant it (cure illnesses).

    Orthos Advisory AG helps clients integrate these objectives and aims to invest with minimum costs and maximum consistency, following these principles:

    1
    We will help our clients in their investment and financial needs to the best of our abilities; we will not, however, engage in any mandate or consultancy which requires us to commit to unrealistic strategies, goals or expectations.
    2
    We believe in aligning our interests exclusively with the interests of our clients; we will be compensated only by our clients and will receive no additional emolument from banks, brokers, funds or other investment service providers.
    3
    We will always act and communicate in a transparent and clear way.
    4
    We follow the same principles in investing for our clients as we do for ourselves: if we wouldn't buy it for our own account we will not recommend it.
    5
    Investing is not about growing a business, but about doing the right thing for the right reasons; we will adhere to our investment process until something better comes along, and will not heed temporary market fads.
