ABSA was bought out control-wise by Barclays in 2005. Its a funny old world, when you re-read some of the news from that time, and think who runs which show.
8 May 2005 – "Absa, Barclays deal approved | Fin24 | Companies | Finance Minister Trevor Manuel has approved the much anticipated deal where Barclays plc ..."
Anyway, now ABSA has brought out a profit warning - so one might wonder if Barclays' knickers are or should be in a twist.
This picture does show the price knock since the profit warning (red), but it also shows the dividends paid in green (most now goes to London, to Barclays, with the bold arrow indicating the deal date).

So yes, there has been a shareprice impact of around 8%, but the dividends paid out have trebled in the 7 years since the deal was struck. So, if one thinks fundamentally, should Barclays panic as much the shareprice might suggest?
