If shouldn't be posing in your thread, let me know...
How do you calculate AME? I don't understand really what it is or how you are calculating it. Thanks.
I'll use ENPIX in this example.
ProFunds states that the objective for this fund is:
"Seeks daily investment results before fees and expenses, that correspond to 150%, of the daily performance of the Dow Jones U.S. Oil & Gas Index. "
Market Exposure (ME) for any given day:
ME = LF*PS/AS
where
LF = Leverage Factor of fund (determined by ProFunds)
PS = Position Size
AS = Account Size
For example, if we take a $20000 ENPIX position in a $45000 account:
ME = 1.5*20000/45000 = .667
AME is calculated by taking an average of all daily MEs.
By definition, the benchmark (^DJUSEN in this example), has a constant ME (and therefore AME) of 1.0.
