Having always been a learning machine, I speak five languages, have worked as a sales agent, project manager, translator, computer consultant, software engineer, built a house with my own hands, published books and essays on literature, philosophy and art, have written for magazines of various kinds in different countries. After retiring early in 2004, little by little, I have become a fund manager for some friends and myself, following the principles of value investing laid out by Benjamin Graham, Phil Fisher, Charlie Munger and Warren Buffett. You can read about my thoughts on a suitable portfolio structure for early retirees here. My articles should not be considered to be any kind of investment advice. What suits me well is not necessarily good for others, as successful investing is somewhat like a marriage: If only one is perfect, the marriage won’t work. So please do your own research and remember Benjamin Graham's advice: “The investor’s chief problem — and even his worst enemy — is likely to be himself.” PORTFOLIO I run a very concentrated portfolio with 10-15 positions and invest for the long term. As of 12/2016, my largest position is Theravance Biopharma (TBPH), a company I had intensively and extensively researched long before any sell-side analyst noticed the stock. You can find my early work on TBPH on this site and my comprehensive in-depth research reports on all important pipeline assets here. I correctly predicted the evolution of the new GOLD guidelines for COPD, the sales trajectory of Vibativ and GSK's new Ellipta product range. My reports have been far ahead (in terms of depth, scope and reliability) of all sell-side work on TBPH. That said, I obviously make mistakes as well, although I've yet to make one that costs me serious money. Other long-time favorites of mine are DaVita (DVA), IBM and a few European small caps which I have also partly covered on Seeking Alpha, e.g. Admiral (AMIGF), Fuchs Petrolub (FUPEF).
