There’s a whole lot of bank bashing around at the moment but it does depend on who you are. If you're a wealth accumulator, you might be a bank seller but you’ll have to work out your profit versus your capital gains tax implication.
However, if you’re a bank buyer for the dividends primarily and have been happy to collect the capital gain, then you might just as well cop the dive in share prices and buy again when they get even lower (read James Dunn’s article today for an analysis of the financials of the big four).
The future for banks
I say this because I reckon bank share prices will recover but they might not go as high as you would hope.
