Hi Ls,
Very nice analysis!
In my research department AIM machines are papertraded with buy safe 20% and sell safe 0%. Every sell is Vealied, so the buy price is moving upwards all the time, roughly 20% below the all time high.
When there is a buy signal, entry can be considered.
You are using the real SP500 for the 20% pullbacks. When the downmove is fast, I guess nominal and real are similar. When the downmove is slow it could maybe even the case that -20% nominal is deeper than real, because nominal moves up through positive inflation? Maybe the 20% pullbacks could also be used with the nominal SP500.
I love your 10%stocks, 10%gold, 80%cash. Low stdev and always ready to enter a new machine, perhaps target 105% of start value.
Using V20A (Lifestrategy 20% Acc) as cash, would improve cagr but increase stdev and max drowdown. Best to enter V20A with papertrade parameters (buysave 4, sellsave 4), or target 110% of start value.
