This is quite complex and I only understand the basics-so please do not shoot me down.
AT trades are pretty much always institutional or investment bank derived.They often (but not always) occur when some sort of corporate action is going on (which may or may not result in anything actually happening).An example is someone trying to acquire a good position without driving the price up, so an algo will work out when to sell and keep the price down(can basically be done by any sophisticated market maker (and I mean Goldman,JPM,UBS, not Shore or Peel Hunt) to facilitate clients who say want to build a good position under the radar.Positions can also be hidden by using nominees like State Street or Pershing to hold the shares on your behalf-quite a few US institutions do this so the rest of "The Street" cannot see what they are doing.
It is very frustrating, but not much us PIs can do about it-but do remember-however,inefficient or manipulated a market is-true value always outs eventually.
