Interesting read. His investment philosophy seems to be based on the notion that there is only one strategy that should be used in all perpetuity. Inevitably then, his strategy is diversity. What I want to know is where to put my money to minimize loss in the face of another recession. Then when that storm passes I will move it elsewhere. From what I can tell, the best bet given those goals would be a so-called high-interest savings account... for a few years.
A properly diversified portfolio, over the same time frame (5yrs), will yield 6-7%.
