Nearly all VC get converted shares at considerable discount and sell immediately for profit on each conversion, hence the slow and painful walk downs. 13g's are avoided by converting and selling piece meal amounts over several days or weeks. I've watched daily T&S's on enough diluters to know this to be fact. Sometimes they run after the dilution is sold and sometimes they don't, depending on the story and sector, and whether or not the dilution stops over time and is accretive.
Take it or leave it, that's the way it works in most cases. VC running stocks is getting rarer than hens teeth anymore. If a penny runs it's more than likely insiders or groups doing the work.
Trading/investing without chart analysis is like bringing a knife to a gunfight.
