Unless the big buyer has received positive inside info and in addition to this big buy has not finished buying yet. The market makers were filling this order all day (or maybe they were trying to fill it over a couple of days) which may account for the shake from the 11p range and once they had enough shares to fill the order the price returned to that level. Has this buyer completed his order or is there more, does he know he has a few more days to get the rest of his order together. He's not playing with pocket money !
