Price changes are calculated on the basis of the following formula: [ avg(x) - avg(y)] / avg(y) where:
x = instrument's 7 closing prices after the news has been released
y = instrument's latest 7 closing prices before the news was released, including the day of the release of the news

Please note that the news releases are only one of the multiple factors that could have had an impact on the change in the security’s price over the time period analysed by the News Analysis tool. Where data are insufficient the graph does not show any price change and the table below the graph displays a blank “ - “ next to the line indicating the RNS issue.
