About
I have been deeply interested in financial markets for many years. Through different market phases and crises, I have developed a clear conviction: Long-term success in investing is not built on forecasts, but on clear rules, discipline and a conscious approach to risk.
With over 20 years of experience in IT as a business informatics specialist, I bring a systematic and analytical perspective. Global Portfolio was born from the question of whether a robust traffic-light system can be developed for different asset classes that remains transparent and is not tailored to past data.
The System
Combines trend, momentum and volatility. It does not try to predict the future, but helps to better classify market phases and identify risks early.
Technology
Modern AI tools help to further develop models and test ideas faster. Not as a black box, but as a tool for better analysis.
My goal is a transparent and comprehensible approach. Not the most complicated system possible, but one that I trust myself.
