Masta,
How do you come up with refund? Sue, settle, pool the proceeds to give a cash dividend.
Letting it trade? Do you even understand why brokerages do not comply if facing huge payouts? They wait to be sued because judgments will actually cost far less than covering in the open market.
There will never be a market cover in this stock. Never.
By sitting back and waiting to be sued, the brokerages will reduce their financial liabilities on this stock. Plus, judgments allow brokerages to dip into their insurance and bonding versus having to use their own cash proceeds to pay out.
