alt Hacker NewsIn some countries (like Switzerland) you don't have any capital gain tax __unless_ you are a professional investor. What makes you a professional investor? One of the things that can elevate you to that status is the amount of trades you make.

Unless you have huge amount of money to play, there is no need to buy dozens of stocks every month. If you already have a portfolio of several stocks, you can buy just one or two every month and increase your portfolio. If you are just starting, you can buy a few more, or decide to start just with the most boring and safe stocks like coca-cola or IBM.
