Event study methodology? Can anyone show me how to calculate the normal return, abnormal return and also cumulative return (CAR) to be used in an event study methodology for the stock of RBS - http://uk.finance.yahoo.com/q?s=RBS&m=L&d=
I know the formulas to calculate these but I just don’t know how to apply them and what figures to use from the above link.

Any help would be greatly appreciated!

Thanks
