Fund trading problem
Let's say that I have one of those systems that seems to good to 
be true.   Relax, I didn't get it from Joe.It makes 100% 
per year with a 6% DD.   As I said, too good to be true.Of 
course, it makes some assumptions.   I designed it to trade the 
ProFunds Small Cap Funds (long and short).   The tickers are SLPIX 
and SHPIX.   I'm assuming that I will get my buy/short signals 
just prior to the market close and that I will enter on the close and that 
my slippage is going to be zero.   I might add that this is NOT my 
normal mode of trading.Since these funds are supposed to "closely 
follow" the RUT and since data for these funds doesn't go back very far, I 
used the RUT for my design and backtesting.    This is where 
I got the results that were so good that I was ready to tell my wife that 
she won't have to be waiting tables and the local pub.For the final 
test, I decided to try it on the ProFunds tickers that I mentioned 
above.   Of course, data for these only goes back to 
2002.   Well.... since 2002 the system didn't do as well trading 
these funds as it did trading the RUT.   The difference was large, 
but the results were acceptable.   My wife could switch from 
full-time to part-time work.My question was/is "why the disparity 
between RUT and the corresponding ProFunds?".    I decided to 
go to the ProFunds site and see if they have a comparison of performance 
between their funds and the RUT.   There it was, big as could be, 
the performance of their funds HAS NOT done as well as the RUT over the last 
year or so.So, the big question.   Does anyone know why this 
is the case?    I will, of course, ask ProFunds to 
comment.   But I thought that some of you mutual fund traders 
(Fred?) might have a more realistic answer.   How can they say 
that these funds track an index when the performance is as much as 10% 
different over some quarters?Please hurry... I'm calling my wife in 
New Zealand later today and I want to make sure I have my facts right before 
I tell her that she can retire.Thanks!Send BUG
