We believe that a successful process, applied consistently, is the key to investment success. Each of our ATDynamic Alloca�on Funds is built with the same basic framework and core principles: a coresatellite approach, globally diversified across mul�ple asset classes, ac�vely managed, all at a low cost. Adhering to these core tenets allows us to build efficient por�olios that remain consistent across any risk profile.

About the Funds We have created a suite of globally diversified por�olios, built with varying levels of risk, all wrapped up in a fund format for easy selec�on. Simply select from 5 different ATDynamic Alloca�on funds and let American Trust do the rest. The funds use a coresatellite approach where nontradi�onal asset classes (satellites) are combined with a tradi�onal por�olio (Core) to improve overall diversifica�on and por�olio efficiency. We combine up to 14 different asset classes, in amounts consistent with each funds risk profile, to build a baseline alloca�on for each fund. The subadvisor, ATCapital Management, then ac�vely manages the mix of each fund–overweigh�ng asset classes that appear a�rac�ve and underweigh�ng those that do not–all within specific guidelines set for each ATDynamic Alloca�on Fund.
