ever since that crappy IPO interinactive brokers has been in the dumps
Quote from Thug_Life:
haha, we are all outsiders competing with insiders. That goes for any financial market.
Does insider option trading, assuming it exists as described in the OP, not leave tracks on the tape? Tape reading is not competing with insiders; it's trying to follow them. If the theory of corruption is true, then there should be a way to profit from it.

They typically only delta hedge? I would have thought that, based on their position as a MM, they could profitably leg into a conversion/reversal?Quote from Equalizer:
Using simple delta hedging, for small market movements - all is cool. As soon as things get a little out of whack they re-hedge. The problem occurs when the movement is rapid and huge - such as a gap from takeover info, then you get wild swings in delta and if that was what your hedging strategy was based on then you're most probably shagged as you're now essentially unhedged.
Yeah, I wondered about that too. But my head hurt, so I gave up.Quote from Jaxon:
Wayne, who do they buy the puts from to do the conversion? They might as well just buy the calls back.
