I'm wondering if anyone knows of an easy way to find out companies that currently have a low stock value.

I'm mainly interested in science, technology and entertainment/film companies.

Obviously my interest is to look through and research these companies and see if I can pick any that may grow rapidly, unless my approach is wrong? I'm a bit of a newbie investor.

Have you got an actual analitical stratergy??

Wow, just found Google's Stock Screener.

It lets me type in a price, market cap… anything I want, and then pick from different sectors and returns company symbols as results. Exactly what I was looking for! Thanks Google.
