The mathematician of finance
Investing isn't guessing. It's measuring, comparing and deciding with a method.
I'm Basilio Mijailidis, a stock market finance specialist. I have traded international markets since 2001. I hold a bachelor's degree in Applied Mathematics and Computing and I'm a Master's candidate in Stock Market Finance, both from UNAM. I teach investing with a method: measure the risk before chasing the return.
