Lewin Buying Stocks

The aim should be long-term investments in what I consider to be the best stocks. Concentrated wikifolio with a maximum of 15 positions. The goal is to achieve long-term out performance versus MSCI World, SP500 and NASDAQ 100. My decision-making shall be based on fundamental analysis, qualitative analysis and partly technical analysis (charting). I'm selecting in my opinion the best stocks. After potential characteristics such as strong leadership, high gross margins, (rapid) revenue growth, strong recurring revenues, positive and growing free cash flow, a dominant market position and a bright future. Stocks from all industries and countries can be selected. The investment period should be predominantly long-term.
