In the case of OCCF, it was to hide distribution of shares being unloaded into the open market.
So they generate volume of 500,000 shares each day, selling maybe 10,000. The stock would bop around, but every 2 - 3 days it would be lower.
They were trying to unload about 20 million shares.
It took them about 3 months to do it.
