Hi Jaiml RE LETF's
How would one go AIM'ing such a portfolio?
Just paper AIM S&P500 (SPY) as your would normally, but adjust the 50/50 2x/bonds to whatever AIM stock value was being indicated. $8000 SPY stock value, $2000 cash, initially held as $4000 SSO, $6000 bonds.
Later if AIM was suggesting selling down from $10,000 SPY value to $9000 then adjust SSO to $4500 value. That has the effect of realigning back to 50/50 weightings in SSO such that its more likely to track the 1x more closely. You should consider periodically rebalancing SSO back to half the AIM SPY stock value (half as much in SSO as AIM SPY stock value amount) - perhaps once a year if AIM hadn't indicated any trades at all that year.
Regards.
Clive.
