This E10/P is earnings for last 10 years adjusted for inflation then averaged and divided by stock price. It gets you a number that is comparable to interest which is a sort of earnings divided by price thing.John wrote:
1. This doesn't show that E/P is correlated to inflation, which is
what you were claiming.
2. I'm not sure what "CPI adjusted E10/P" means, since CPI is
factored into both the numerator and the denominator.
3. This is the nutty "Fed Model" investment strategy, which
I wrote about several times. It's based on a single paragraph
in a 1997 Fed report.
This just shows that E10/P is correlated to 10 year bond rates. I would then have to show that bond rates are correlated to inflation to prove what I was claiming but that seemed so clear I have not done so.
Calling this a nutty investment strategy based on a single paragraph when there is data in the article showing the correlation seems odd. Bonds and stocks compete for investment. It makes sense that when yields are low on bonds the earnings relative to price would be low on stocks as well, which means a high P/E. When inflation is high, and interest rates are high, like 1980, then stocks have to have a high earnings per investment to look competitive, which means a low P/E. This is not just some nutty idea based on a single paragraph someplace.
