I've been investing in the micro cap stocks since 2004. Over the years I have learned and perfected what to look for in a company and what to ask when dealing with management. There is a criteria list that I created and if everything is met on that list, then I purchase a certain stock.
Most investors shy away from the juniors because they don't know how to approach them. Due Diligence is critical when dealing in this range of securities.
I like to buy early stage eps growth companies or mining stocks with decent cash positions.
