ill try to answer that for you as best i can. i see you are new and only post here, so i wish you well for sure.
now, some stocks may have news coming and some insider maybe, buys and that signals other buying. some runs for no real reason.
its "set up" cause the .0001's appear to be bought up and its like a ticking time bomb.
some may sell higher and hold for the super highs in case that happens.
why do some from from .0001 to .005 and others just a little? dont really know.
just get ready and do what is best for you. most will not post when they get in or out.. its really a personal choice. :-)
