This is why the inflation rate is really the rate of increase of the money supply, not prices. Price changes (or non-changes) are partially an EFFECT of inflation. They are also partially the effect of other things. Unless you think inflation makes some prices go up and some go down (this is silly, it makes dollars worth less than they otherwise would be so it's effect is not really on things but on dollars).MediumTex wrote:What is "true" inflation?Marc De Mesel wrote:frommi, how can you judge your investment returns if you don't know the true inflation?frommi wrote: I really don`t see the point in this whole discussion. Even if personal inflation rate is 10%, what can you do about that? You can buy other products, or reduce your consumption or choose to live in a smaller house. But it should have zero influence on your way to invest your money. Risk/reward is the measure that should dictate your investment style, but please don`t measure risk with backtests, because all risks that matter are in the future.
Is it whatever you decide it is?
What if I decide it's something different?
What if every single penny I spend supports my beliefs about the nature of "true" inflation?
On what basis would you be able to tell me that my beliefs were wrong if every single experience I ever had validated and supported those beliefs?
Increases in productivity would result in consistently lower prices every year in general. Sometimes the inflation is only enough to prevent the falling prices. It still cost you though.
Measure the PP against the increase in the money supply annually and I doubt it will be posting a real return, particularly after taxes and fees. It's 50% fixed dollars and 25% gold so it's 75% money (if you consider dollars money). Stocks might go up nominally with inflation, but inflation hurts the economy and businesses I've explained this so many times I'm not going to do it again.
The PP is skewed towards deflation. It's very close to Browne's original deflation portfolio and far from his inflation one. High inflation (increases to the money supply) expose the weakness of the PP. Hyperinflation would be catastophic to it.
That being said it's pretty good all the rest of the time.
