Alan Reynolds introduces us to “The Reynolds Model” in this latest post:

The Reynolds Model of Stock Prices


I may have discovered “the Fed Model” in March 1991– long before Ed Yardeni gave it that name after July 22,1997. The relationship between the inverted P/E ratio and bond yields was first depicted in the letter below to consulting clients (institutional investors), where I probably should have labeled it the “Reynolds Model.”

I agree with Estrada that it did not work very well before August 15, 1971, when the last remnants of the gold standards were abandoned. The gold standard did not permit the extreme gyrations in bond yields we have seen between Fed Chairmen Volcker and Bernanke.  Relatively steady bond yields of 2-5 percent from 1789 to 1970 under a gold standard obviously tell us little about stock market booms and busts at that time. Contrary to Hulbert and Estrada, however, the U.S. relationship between the e-p ratio and the 10 year bond yield remained remarkably tight from 1970 to 2008. From 1988 to 2008, the e-p ratio averaged 4.9 and the 10-year bond averaged 6 percent.
