It is my understanding that mms get away with this by making a fair and orderly market for a security. they do not have to cover until they choose to. however, one usually flips before the other. and when just one mm joins our side and starts buying, it's lights out to the rest.
i would suggest looking at the sec and finra regs. they both have search options.
