My retirement account has been in the Ultimate strategy and fully funded since around 2009. I had many of the components earlier, but the weights had not been balanced until that time. I use AIM on each component with each one having its own cash reserve. It's done nicely over time.
We've given this a new name - Ultimate Buy and AIM Strategy or UBA for short.
If you read through each iteration I think you'll see what the author is suggesting. I've picked ETFs for the various components so that I can trade them when AIM gives me the proper signals. It's not a hyper active portfolio in that most of the components are "style" based funds (small, mid and large cap value in the US and ex-US markets along with REITS, gold, corporate bonds and some govt. bond influence). Don't forget the all important ingredient of CASH that is not in Ultimate Buy/Hold.
