all going to plan, page-50

It matters Spon. unless you're ok with naked shorts wrecking sp again. I've found his thread on it anyhow

Allegedly: "I can only state what my broker's requirements are for spec stocks. I cannot speak for other brokers.
You must be officially registered with said broker as a sophisticated investor.
You must have at least three times the short value on deposit in a cash account with said broker.
You must agree to employ a stop loss whereby the total potential loss does not exceed what you have on deposit."

Maybe this can be done if his broker owns stock to cover it or but I do not see any broker bothering with this sort of nonsense and risking their license. as I still believe its legality is questionable. I will certainly be following up. I'm a registered Soph trader myself and use several brokers so it matters.
