It is not the mm's that manipulate the price. It is large shareholders placing buys and sells at their target prices. MM's can't trade for themselves.
A market maker makes a profit by attempting to sell high and buy low FOR THEIR CUSTOMERS. Market makers establish quotes whereby the bid price is set slightly lower than listed prices and the ask price is set slightly higher in order to earn a small margin. Market makers are useful because they are always ready to buy and sell as long as the investor is willing to pay a specific price. This helps to create liquidity and efficiency in the market. Market makers essentially act as wholesalers by buying and selling securities to satisfy the market; the prices they set reflect market supply and demand. When the demand for a security is low and supply is high, the price of the security will be low. If the demand is high and supply is low, the price of the security will be high. Market makers are obligated to sell and buy at the price and size they have quoted.
So, instead of blaming MM's, blame your kindred shareholders. THEY are the ones that decide to buy or sell large lots, and set the price they need to do so.
