Each MM has their own position to worry about, that would be either sell short, cover, and ultimately execute trades etc. In most cases MM's have no clue about the company and don't care. That is why time to time they can get caught themselves if the stock starts to skyrocket, but out of all the stocks out there odds of that are slim.
If the stock goes way up, they will sell shares, if it continues to go up, they will sell shares again to cost average, they will do this over and over and 9/10 times they will succeed.
If they went short at 0.12 with 1M shares, and price goes to .13, they will go short again at .13 with 2M shares. Goes to .14, they will go short again at .14 with 4M shares. Now their average is .134.
They do this because they know as with every stock it has to correct at some point. Once buying starts to slow down, they will start playing with bid/asks and try to induce selling at which point they will start to cover with their breakeven only at .134.
If the stock prices continues to go up, then the MM has to make a decision, either they keep firing or they have to cover at higher prices and cut their losses. They will do this if it gets ugly for them, but 9/10 times they will succeed at what they are doing.
So yes manipulation happens, yes they try to control the situation, but they are like a day trader. They are not investors, 99:1 odds that they have no clue about Sigma Labs but work with the parameters that the market gives them.
