KG: In all seriousness, if we MUST be here on Saturday evening (where I izzz, anyway) ... Market Makers can essentially do just about anything they want to, at least down here in Pinksheet/OTC land. The SEC has given their blessing in silence to be able to, and evidently the rest of the Feds seem to have also.
Would you trust the Mafia? Don't think so. Would you trust hedgefund managers? You better NOT! If you become a "good" Market Maker, talent scouts might dangle the HUGE golden carrot in front of you and allow you to manage a hedgefund.
Moral of the story? MM's look out for the hedgefunds, or ELSE! (But please don't tell anyone okay? We'll just keep that a little secret between you and I).
