In comparision to AAZPB which is similar trust/hybrid security which has been stepped up to BBSW+4.8 is trading around $80-82 compared to MXUPA below 80 with BBSW+1.9
As MXUPA presents less general risk thank AAZPB I expected even stepped up to BBSW+3.9 that MXUPA should trade 80-85 into the forseable future on a fair value basis with running yield around 10%
My entry price is also around $50
