Our models analyze the complex, constantly changing interactions between valuation-relevant data and price developments on international stock and bond markets. The asset classes with the highest risk premiums are continuously identified as the basis for tactical portfolio decisions. Machine learning is carried out in the context of the conditioned valuation models that have been tried and tested in practice for many years, whereby the data space for conditioning risk premiums is larger by dimensions than in the context of econometric approaches. In addition, non linear relationships between influencing variables as well as possible structural breaks in cause-and-effect relationships are captured by the learning algorithms.
