I traded those news releases and earnings announcements for almost 10 years. There is no information leak on the news side. The market becomes completely silent leading into the second before the release (some countries do have issues though, but relatively small). Earnings announcements are a little different but still not a problem. A scene like Trading Places FCOJ isn't happening.
