Finance Returns Calculation - DAX

[sv12]

Hi, 

I am trying to calculate and visualize cummulative returns for Funds (Ex: S&P 500). 

I have daily performance data for the fund. 

Desired Output:

Making the measure dynamically start from 0% for the selected date range and then calculate returns from there. 

Example: 

Challenge/Issue: 

I would greatly appreceate any help in making the calculation start from 0 for any selected date range. 

This is where I am at currently:

Return = 
CALCULATE(
    PRODUCTX(Table, 1 + (Table[DataPointValue]/100))
   , FILTER(ALLSELECTED(Table[AsOfDate]),  ISONORAFTER(Table[AsOfDate], MAX(Table[AsOfDate]), DESC)
    )) - 1

Sample Data:

@sv12 , when every you do such calculation use date table

Return = 
CALCULATE(
    PRODUCTX(Table, 1 + (Table[DataPointValue]/100))
   , FILTER(ALLSELECTED(DATE[AsOfDate]),  ISONORAFTER(DATE[DATE], MAX(DATE[DATE]), DESC)
    )) - 1

I used like

Cumm Sales = CALCULATE(SUM(Sales[Sales Amount]),filter(date,date[date] <=maxx(date,date[date])))
Cumm Sales = CALCULATE(SUM(Sales[Sales Amount]),filter(date,date[date] <=max(Sales[Sales Date])))
