Sony's data is in-house and they were seriously hacked. Networks and servers are hacked not physical buildings. Your thesis makes no sense.
So, UBS rates dlr a sell and the stock sells off. UBS lacks a highly regarded reit analytical team, good day to pick up some shares. My guess is that dlr snubbed ubs on some fee raising scheme, and UBS is pissy about it.
The UBS analyst has had a negative view of DLR for many years. His price target a couple of years ago was about $45. Creates a self fulfilling price drop when he takes a public negative view. Very beneficial for UBS' hedge fund clients who are short(?).
