I like the theory but in reality the bulk of the liquidity on the OTC anymore is in companies generating some type of awareness, generally through promos or ones that people at least believe will run an awareness campaign of some sort.
Real, legit companies and DD still have a place but it's getting more and more inconsequential now in this new market.
With that said I marked the board though and will be interested in seeing what you dig up.
There is no reason a person can't do both, trade some promos stocks but also keep a core position of long DD plays as well.
