UUP versus DXY…DXY is an index of 6 currencies, largest of which is 58% Euro and 14 % Yen….whereas the UUP is an ETF and has only 50.4 $ Dollar index futures and the rest 10.9 % T Bills. 7.6 Investco Treasury ETF !!!! and God knows what else.Then subtract all the charges…wheras DXY has none…so over time they must diverge.
No way does it mimic the DXY 100 % it never can.
