I just try to understand what happened to the Google stock. In October 2013 many newspapers wrote that the GOOG stock reached 1.000 USD.
When I now look at the charts for this share and scroll back to October 2013 the value back then was at about 500 USD.
So, what happened to the Google stock? I am sure when I looked at the charts in October, they displayed 1.000 USD, but now they don't. Can the values be changed at a future date? If yes, why?
