DaddyBigBucks - a large holder who wishes to sell can either trickle the shares into the market themselves, or if they cannot be bothered and like getting ripped off they may have said to a Market Maker when the price is 40p - "hey bud can you sell our 10M shares by the end of November ?", to which the Market Maker will respond, "why yes indeed sir, and would sir like to come through to the back room, the one without any windows, whilst sir waits" at which point they let the price go up past 45p whilst selling the shares that they don't yet have so that Buyers can pay for the right to watch the price be walked back down to 40p.
Such a Seller might go be the name of First Island, but other large myopic holders exist.
Instead of getting 0.25p on the spread the Market Makers can instead get 20x this by trading against buyers. They do this simply because they have control over the share price and therefore have all the aces in the pack once a Seller gives them carte blanche.
The only risk is that whilst this is all going on big news lands and large amounts of day trading money turn up to swamp the MMs short position. This risk is clearly considered as acceptable as simply the cost of running the business of ripping off amateur mug punters.
