nervouswreck,
IMHO you have a better chance of picking a winner if you spread your risk a little. Not just by concentrating on a single one. IMHO, that is the way the stockmarket works.
Hence why some have been able to pick winners, while others have not. Not yet anyway. Maybe one day, but that is a long drawn out bow.
Both AZO and DTE (following AOE) have proven such a theory.
Good luck mate.
