BRK = Berkshire Hathaway

Actually most bank (MAYBANK, PBBANK, HLBANK, CIMB) can achieve a net return (equity gain + dividend) of more than 16% CAGR over the past 10years.

I assume Bank Rakyat already stop accepting new investment since 10y ago and its NAV remain the same.
Bank Rakyat net return is actually worst than most other bank above.  The published yield of 16% is very misleading.  If PBBANK were to introduce a similar scheme, it can easily achieve 25-30% yield.
