I have to respectfully disagree with you on this. The job of the MM is to "make the market" (hence the name). It's all about VOLUME to the market maker. There main objective is to keep the stock moving at a "controllable" pace. If new investors are buying at the ask then stock price will move up. On the contrary, if new investors are sitting at a lower bid price and there is no upward movement in the stock then current investors get bored, sell their shares and move on. When the current investor sells his/her shares at the bid they are sucked up by whoever was sitting there waiting to get them. Now here's the problem with that -- the person that was sitting on the bid gets their order filled and now they fall off the bid which makes bid support WEAKER! That's why so many people on ihub and other boards always talk about "slapping the ask". Stocks don't go up unless people buy at the ask price. If they are constantly bid sitting then it will continue to move down because as I said earlier the investors that were there before you will get board and move on.
People (including myself in the past) are so quick to say the MM's are "manipulating" the stock but with the exception of institutional MM's they're just doing what we tell them to. If the MM's can move a stock up in a controllable manner they stand to make much more money than bringing it down BUT THEY CANNOT MOVE IT UP UNLESS INVESTORS ARE BUYING.
Bottom line, if you are looking to go long on a stock it's always best to buy at the ask. After all if the bid/ask is .0059x.0060 are you really going to go broke if you buy at .006 rather than .0059. REALLY - if you buy 100,000 shares at .006 it only costs $10 more than at .0059 and you will be contributing to the stock price going up.
