Basics of Value Investing


Margin of Safety

We estimate a companies ‘intrinsic value’ if it seems to be undervalued by the market. We only buy stock as soon as the stock price has reached the ‘margin of safety’. If the market gives the stock an adequate price or the intention of the buy-action is lost, we sell the position.

Business Owner Concept

A management that owns a lot of its company will establish safety and confidence for investors. A high participation of the management in the ownership structure leads to high responsible awareness, as it is often the case especially for family-run companies.

Economic Moat

To be able to make sustainable, long-term investments, we have to find companies that can build up and hold market advantages over a long time; e.g. through network effects, high entry barriers, switching cost or economies of scale. 

Mr. Market

Stock markets tend to be emotional, waving between enthusiasm and fear. Often we are able to observe unjustifiable tranquility. We avoid market risk by strict criteria, diversification and constant, long-term investment strategies.
