I am interested in experimenting a bit with inexpensive stocks, so I thought I might try buying some penny stocks and seeing what I could do with them. I want to do my research though, rather than just choosing random stocks. I am worried that I might end up losing a lot of money through trading fees though. Can anyone recommend a good website for trading penny stocks where the fees are low? I would love to find somewhere to trade these stocks for free, but that might be too much to ask for I suppose. I am just getting started in my research now.
