When a market maker agrees to "create " a market for a stock one of the things he has to agree to is the size of the spread. This is how the MM can make money. As long as he stays within the spread, he can buy and sell all day long from shareholders skimming off the spread between the bid and ask and pocket the difference. That is how the market is created, he is effectively selling or buying shares to put in his own stable. So, all he had to do is operate within those parameters. Obviously the price is dictated by what ppl are willing to buy/sell it for. He has to again "create" a market for the stock so it is in his interests to keep the pps betwixt those ranges.
Somewhere in their listing agreement you will find the size of the spread that they agreed to.
