" the big four " ?....
over the past 10 years....CBA share price is up 88%
versus 28% for NAB , negative 6% for ANZ and negative 10% for WBC....
since 1992 CBA share price is up 1400% versus 334% for NAB and 650% for ANZ and WBC
NAB, ANZ and WBC dividends in 2021 were smaller than 10 years ago but CBA's were higher ( $3.50 in 2021 versus $3.32 in 2012 )
the outlook forward is debatable but I don't think you can lump all the banks together over the past 2 or 3 decades.
which is why I continue to stay away from 3 of them as long term investment.
