Haitiwebs: That's good info, I have a lot to learn before I invest real money. I'll have more time to research companies after my board exam.
Al: Finance courses shows you a bunch of cases and example where companies went bankrupt with speculation. The one I remember is about a bank, the guy was supposed to wait for arbitrage opportunities instead he daytraded and lost a bunch of money while cooking the books. The Bank went bankrupt and got sold for 1$. Do you know this story?
