My understanding is this.
Say a buyer wants to buy at 1.1p. The MMs 'borrow' the shares to sell, waiting for someone to sell at 1.05p. If the share if promising, nobody wants to sell so the prices needs to go up to tempt sellers so the MMs can return the 'borrowed' shares.
Problems start when the MMs have 'borrowed' lots of shares but nobody wants to sell. They cant just raise the price to get ppl to sell because they'd be out of pocket, (and the number 1 rule is that the MMs always have to make money) so funny stuff starts happening.
