I am a chemical engineer with a MS in Food Technology and Economics. I am also the author of 2 mathematics books ("Arithmetic calculations without a calculator" and "Word Problems") and perform almost all the calculations in my mind, without a calculator, making it easier to make immediate investing decisions among many alternatives. I invest applying fundamental and technical analysis and mainly use options as a tool for both investing and trading. In my spare time, I follow Warren Buffett's principle: "Some men read playboy. I read financial statements".
