Since I seem to been spending lots of time inside these days, I ran AIM against SPIP back to the date of initial introduction. It has a longer history than TIPX, but both show similar results across AIM settings.
There's not really sufficient price volatility to make either of these worthwhile AIM candidates.
Model Setting:
Starting Capital: $10,000
Stock-to-cash ratio: 70%
Buy & Sell SAFE %: 10%, 10% for all iterations. Buy SAFE % incremented by 10% on subsequent buys and decremented by 10% on subsequent sells.
Minimum Order as a percent of Stock Value (Buy, Sell): Where 0% is used, a minimum of one share will create a buy or sell event.
Interest Rate: 0.0% for all iterations
Special Cases:
30-Day Buy Rule: Wait for 30-days between sequential buys.
Inc/Dec Buy SAFE %: Increment Buy SAFE % by 10% on each subsequent buy and decrement Buy SAFE % by 10% on each subsequent sell, down to a Buy SAFE % floor of 10%.
Vealie: Implement a Vealie each time a sell event is encounter when the cash value to portfolio value exceeds 30%. (Note: taking a Vealie does not reduce the Inc/Dec Buy SAFE % value.)
