iwanttoknow sometimes a seller of large parcels may be buying anything under that price the big parcels are listed at so is trying to cap the price while they accumulate shares. Often in the course of sales you can see small parcels traded frequently. They may also sell some to keep knocking the price back into the range they want to buy at...................Algorithmic trading also is going on all the time as well with certain stocks and all the above is associated with this also.
Was interesting that the big 200k parcels did not move when the big 351K seller popped up in the last half hour for a while.Thought they might have been pulled if the were buying and mopped up that lot that was going begging if they were after a chunk..............Not too many that size come up!!
