Try to understand what a ‘ hedge fund’ is, using Wikipedia in German. You will get an article introduction with a lot of unknown terms, and the article itself isn’t much better. Of course, the terms are linked. But in order to understand what a ‘hedge fund’ may be you have to read three, four other articles.
It’s an old misunderstanding of internet savy people that a link facilitates understanding. In fact the link is an easy way-out for the writer. He believes that it is not necessary to explain the term. It is a huge burden for the reader who gets an incomplete text.
