Quote from nitro:
What I still don't quite get is these guys that are standing toe to toe with each other. I mean, it could be hell or high water, and there is someone on the bid. Easier when markets are rising since you can lean on mutual funds that must be long slightly.
The only way I can explain that is they are trading against something else, like a long gamma position against and SPX options position, or perhaps against a short stock position, or any number of more complex "baskets", all trying to get alpha.
Still, as the title of this thread suggests, these guys have taken this to a very high art.
suggestion: rename the title to "Kudos to MFs"
MF=market faker
