Feb 12, 2014 at 14:39 comment added Victor123 Oh this is a matter of confusion to me since a long time. The Bid and Ask is posted by the MM and not by other retail traders.
Feb 12, 2014 at 2:39 comment added derenik Are you asking what is the fair (theoretical) price this market maker trades off? On the other note I think there's an error in your question. The MM bought at 181.77 not sold.

Feb 11, 2014 at 18:38 comment added user2763361 "MM" isn't one individual. It could be HFT or buyside execution. If it is execution, losing trades are consistent since they have a mandate from a client they need to execute with the objective of minimising transaction costs (not necessarily maximising profits).
