Hi
You can try to use below measure if it works on your side:
FundReturnTmp =
CALCULATE (
IF ( MAX([Date].[Year])=MINX(ALLSELECTED(Global_AssetType);[Date].[Year]);100 ; PRODUCT ( Global_AssetType[FundReturn] ) * 100 ) ;
FILTER ( ALL ( Global_AssetType ); Global_AssetType[Date] <= MAX ( Global_AssetType[Date] ) ) ;
VALUES ( Global_AssetType[OrderKey] )
)
