I was thinking this as well, can't some of the reasons you think the PP might do worse in the future also be applied to your own portfolio? Even though many of the people on this forum like to back-test as one form of validation, I think a great deal of respect for the portfolio comes from the fact that it is constructed with asset correlations to economic conditions rather than against other asset classes - that is, it is the PP construction theory that most here are extremely comfortable with rather than just its back-testing history, though its back-testing results alone are certainly quite impressive. Asset to asset correlation changes over time, asset to economy correlations may change too, but it seems to me that the PP has managed to do what it was set out to do for all of its years without fail. It is extremely well diversified with nearly zero correlation between asset classes (I don't believe this was a primary intention, to me this is one form of validation that the assets are likely very well correlated with the different economic conditions and thus are extremely well diversified) - this isn't something you see with a typical stock/bond Bogleheads portfolio. The chart showing positive real return over any 3 years period for the PP is very telling to me. Perhaps it's not back-tested well enough for your liking, and that's fine, people find comfort in different ways.dutchtraffic wrote:ps: your 'perfect storm' would destroy your portfolio more than it would a PP.mathjak107 wrote: what you have to remember is as tried as you think the pp is it has never experienced what we are in ever before . low rates , high stock valuations . that combo can be a huge weight and assets fighting each other does not help the cause since nothing can develop a trend . as these low rates rise the rise will likely be slowly after a knee jerk reaction and may take many years .that can put gold out of the picture too. for the pp it may be entering the perfect storm.
as I said , I am not trying to talk anyone out of it but I am telling you take a good hard look at your plan and make sure it still makes sense because this perfect storm may be just getting underway for the pp. and it is possible the last few years it saw pretty much what it is going to see going forward for quite some time .
but that is for you all to evaluate , I made my decision ..
A stock heavy portfolio is betting on continued prosperity throughout your lifetime. Maybe that will be the case, but just because it has been that way before doesn't mean it will continue to be this way. This is really the crux of the argument - you believe with an extremely high level of certainty that prosperity will continue on (it seems to me mostly because of back-testing that you feel this way), otherwise you would have some hedges against uncertainty. History tends to throw a lot of surprise punches, so a lot of us are probably not 100% comfortable betting the whole farm on one or two correlated assets. Recency bias holds strong due to the stock bulls in our recent past. To each his own, just realize that many on this forum have other justifications besides back-testing alone for holding a portfolio.
Again...I just think it's funny that you keep saying that the future is going to be so different for the PP without realizing that it could easily be applied the other way around to your own portfolio. Only time will tell, maybe you are a Nostradamus - I don't know, but at this point in the game we are probably just talking past you as your pounding of the PP does not seem to end - are you on a PP crusade? Maybe it is a way for you to calm your nerves and reassure yourself since you are about to enter retirement
