Self-directed investor, managing three portfolios for family members and myself. In the former cases I follow Harry Browne's Permanent Portfolio which is the only strategy I feel comfortable recommending to others. With my own money I pursue the more erratic Ever-Changing Game Plan whose genesis is documented in my articles. After buying a stock I virtually close the stock market and keep only track of the aggregate portfolio performance. Some five years later I carry out a review of the respective position and decide on keeping or selling. My first review was about the Australian REIT GPT Group, next on the list will be the renewable energy plays Energiekontor AG and Alterra Power Corp in 2017/18. In my professional life I am working in the mass transit industry where I held executive and non-executive directorships in different companies and countries.
