Cristofer Andersson, born in 1986, is a high school teacher of Swedish and history, holds popular investor courses at Folkuniversitetet, and blogs about the role of psychology in the market. By investing in stable, profitable, and highly prominent companies in their niche, he now lets his money work for him around the clock, every day of the year, year after year. The return on his capital not only gives him a large cash flow but also a great sense of security that he wishes for everyone. Börspsykologi (Stock Market Psychology) is Cristofer's first book on economics, but he has previously published a historical thriller about Gaius Marius, which received very good reviews.
