re: leakage of leveraged funds

The Rydex traders & programs work to make the end result
rise or fall twice as fast as the targetted index, on each day.

Leveraged Rydex funds
RYVYX (NDX * 2) and RYVNX (2* (1/NDX))
RYTPX (2* SPC) and RYTNX (2*SPC)

They seem to succeed pretty well at this. So eg yesterday,
we have RYVYX -10%, RYVNX +10% because of its 200% leverage
on the NDX which moved about 5% down.

Just by arithmetic, a 5% increase followed by a 5%
decrease doesn't leave you flat but down by .25% because
on the trip down you have a higher base to take that 5%
from. The leveraged trip, 10% up then 10% down, would
leave you withe even less, 1st all because its twice as
much to begin with but secondly because the dependence
is not linear. so a +, - 10% round trip that would follow
the +-5% would leave you 1% poorer not 0.5% poorer as would
a linear relation of the error.
The discrepancy increases with amplitude and always works
against the leveraged fund, whether it goes with the index
or is contrary. So these should be used as trading
vehicles only - eventually the value will be sucked out.

Simple tracking funds and their inverses hold up much
better, then. I'm considering putting on equal amounts
in SP500 and its complement in Rydex through Schwab.
In 6 months the capital will be preserved, a little
increased for whatever overall market move has occured,
but transaction-free and ready to trade.
If significant drop has happened and the index
was ready to rise one might take some out of the 1/SPX and
put it into SPX to weight the bet that way. I wouldn't
go that way until at least the IBM/MSFT debacle was played
out.

The SP500 funds are
RYURX (1/SPC) only I guess I'll have to go elsewhere for an SPC fund Rydex doesn't have one it seems.
