Hi Clive
I find your study interesting and your conclusion my be a little hidden for some.
AIM does a pretty good job timing the market.
While buying at the bottom and dumping near the top may do as well or better than buy and hold I know for myself I am not THAT good at timing the market.
AIM gives me a certain discipline to follow. It is passive market timing.
I know I ran out of cash in the 2000, 2007, and 2020 market crashes so it is not like I didn't get to put my huge cash hoard to work.
I honestly don't know how others get buy on this board with 50 % cash as a upper limit. I look at it as a starting point though I am STILL below that now. And honestly, now that I am retired and actually pulling funds from my account, it is even harder to keep the cash reserve up, a reason I hope to accumulate more REITS.
