My name is Mpozardenis Ioannis and I am a graduate of the department of business administration. In the course of the last three years I am actively involved in finance and the stock market by reading books, articles financial magazines and by auditing seminars and webinars. During this period, I have tried various strategies and diverse systems. Each system has its advantages and disadvantages. As for my portfolios, I prefer to use a combination of the systems in order to reduce the risk without decreasing their efficiency.
