The rule is 5%, but on pinks, it is usually not enforced unless it hits 10%. Does it really matter? 5% is almost 2 billion shares. I kind of doubt anyone here is crazy enough to buy that much.
We are apt to shut our eyes against a painful truth... For my part, I am willing to know the whole truth; to know the worst; and to provide for it. --Patrick Henry, Patriot and Hero of the American Revolution
