Look at the increase in volume chart for low priced stocks with extra volume find a small company selling in the 2-4 dollar range, but I would probably put it in a mutual fund its a good exercise to find the very best and aggressive small stock fund really do the research, later copy some of its purchases if you have the funds.
Tough call. If it pulls back in the next few days I think it's a buy. Unfortunetly no one can predict that. If you buy at these prices it might pull back but I don't think it would be a disaster. If you can hold long term you'll do OK.
