In general I am against trading Penny Stocks, except if they are legitimate companies that you have researched and are in a sector which is in a strong trend. I have done very well with junior mining stocks. For instance, I bought 5000 Hana Mining for c$0.37 and it was recently trading c$4.16. I sold half each time it doubled so my initial stake is long since off the table and I'm down to holding only 500 shares... I strongly recommend if any stock doubles, sell half to recoup your initial investment.
