whilst mm's will use a tree shake if they are after some stock, generally they want a stock priced at the point where maximum two way trading takes place - that is their "sweet spot" - as it generates the highest volume and as such they make on each trade. They do not care about much else.
The thing about setsqx, that block trades on, is that the MM's do not have a maximum spread size as they do on sets, so you can quite often see a move up in the price quickly, only for you to be offered far less, when you try to take advantage of the price move.
as hilly says - these guys have countless stocks they make a market in each day and whilst they all will have their allocation to be responsible for, most of them haven't got a clue about the underlying fundamentals of the stock. Block and other stocks like it, get very little analyst coverage and as such market makers could't care less. They simply look at the order book, price accordingly and then buy/sell to meet the demand.
They will fill an order even though they haven't got stock themselves, then go out and try to get it in the market - hence a bit of a tree shake now and then.
Their reputations depend on being able to fill the order - if they cannot, then bigger players go to other trading houses and they do not get the business.
The MM's are not buying Block because it makes a good investment, they are buying to keep a float on hand to meet market demand and it will be a small float at that.
Retail investors generally poll rsp's, get a quote and never deal directly with the market - unless you have DMA of course.
