The concept of the PP is attractive. I like the idea of passive investing, of having a bulletproof portfolio for all seasons, and of not trying to outsmart the markets. However, I am skeptical about stocks for the next few years. I also run a small software business, so in a sense I already own "stocks".
What would be the downside of a PP-like portfolio, but without the stocks? For example, 33% gold, 33% cash and 33% bonds. Or maybe 50% gold, 25% cash and 25% bonds.
I do realize that this sort of tinkering goes against the core philosophy of the PP, as it breaks rule #4 ("nobody can predict the future"). My question is more about the practical risks. In what sort of economic environment are stocks needed to carry the portfolio? How big is the risk of leaving them out? And can I consider my own business as a stock substitute?
