Years ago when i was 21-15 i worked in the City - i was a dealing desk assistant - basically coffee and biscuits. We used to run a book fir about 15 small stocks - AIM sized stuff - this is during the start up of Winterflood Securities etc - if you want a reference point.
Anyway the book was simple - you would take calls and receive bids or offers - most of them pretty small - say sub £20k stuff. As the book got LONG - say £50k or whatever the head dealer set - you would reduce the prices - and if it got SHORT - you would raise them slowly.
We would take a few calls from nervous PIs who would see the price down say 10p and ask whats going on - we would just say more buyers than sellers - most of the time that was the case. Sometimes we would have a few scraps of info too. Once a year maybe we would have a research report from the analysts and the brokers would shop it around for Institutional buyers - but mainly those were big trades off book and off market done as placings.
So I am just saying - the MMs do share knowledge and bits of information here and there - sometimes they get ahead of pricing information and cant help themselves and become very unidirectional on the book, but 99% of the time they simply reflect the flow on and off of the book and are happy to take 1p or so on each trade. The spread on NVCYT is 5p - thats massive - probably the real TOUCH is 127/28 but thats ot the advertised price. When you trade dont do it at best - just throw up a price for say 1 minute inside the spread - then cancel it and reload - you will almost certainly get your price filled. This doesn't work in fast markets of course - but there is price stabilisation these days.
Just saying - the MM know a bit but dont really want to take positions, they just want flow through the book as thats their job and where their profits come from, taking a position gets them outside of their risk envelope and can in fact get them demoted or even fired. Break a leg.
