Surely it can't be a personal investor, is it some sort of balancing act?

A: Say there are 1,100 shares available to buy on the order book. Someone buys 1,080 leaving 20 shares there on the book. The next buyer may buy 2,000 shares but the 20 shares left on the book go through as a separate buy even though the buy was for much more. In the US you actually see these separate buys on your contract note so a purchase of 200 DELL might show as 2 80s and a 40 making up the 200 that you have bought.

Also, not a lot of people know this and there is a reason why, its pretty useless information but...Crest, Bloomberg, UBS, RBS, etc. anyway, most brokers, clearers, settlement banks, data people, all buy 1 share in almost every listed company so that they automatically receive and are entitled to any corporate information. It may not be the reason for any specific purchase or sale but its one of the reasons a buy/sell of 1 share.
