That is crap - you can not generalise about small cap stocks, some large and successful ASX companies started out smaller than HDY today. For example Sirius, SIR or Gold Road, GOR - many others.

The deficiency and the shortcoming is the failure of speculators to adequately research the stocks they buy. Is it that they are just dumbos, or are they influenced by emotion and sharp sales tactics??

So please stop and think.

If you want to invest in Vanadium, read all you can about ASX V stocks - read about the various kinds of V ore (Fe/Ti/V ores, such as CZR - V in oil shale ores, such as IRC - oxidised surface ores, such as VMC - V in veins, such as HDY)

Only if you can't do the research is low cap specie stock too risky for you - learn about yourself and your shortcomings first.
I remember a saying "A fool and his money only came together by accident in the first place". That haunts me - I do not want to be that sort of fool.

For those who can DYOR, I wish you GL, but make sure you spread your risk.
