It's not my formula or my theory.How do you know when to change? I am 60/40 stock to bond at the moment.So if I use S&P 500 Earnings Yield 3 month T-bill I get:Stock Allocation = Shiller PE Earnings Yield / ( Shiller PE Earnings Yield + ST Treasury Yield)What is Graham's formula?Decreasing due to Ben Graham's formula comparing ST Treasury Yield to S&P500 Earnings yield.
About 35 / 65 % stock / bond ratio given current yields.
Bonds more attractive at present time.
You can also see Buffett building cash levels, student of Graham.
I mean, I get the conceptual gist of what you're implying, but curious as to the actual formula.
= 2.95 / (2.95 + 5.5) = 35%
you could also use S&P 500 Earning Yield
I used 1 month T Bill
3.71 / (3.71 + 5.39) = 3.71 / 9.1 = 41% stock
Not that far off
Nor do I follow it, except as a matter of intellectual curiosity.
But there is this:
https://www.grahamvalue.com/blog/adjust ... ions-today"Our basic recommendation is that the stock portfolio, when acquired, should have an overall earnings/price ratio—the reverse of the P/E ratio—at least as high as the current high-grade bond rate. This would mean a P/E ratio no higher than 13.3 against an AA bond yield of 7.5%."
Chapter 14: Stock Selection for the Defensive Investor, The Intelligent Investor.
At today's 5.41% 3 month T-bill yield, that would suggest an earnings raton >= 5.41, or a PE no greater than 18.51.
FWIW:
VXUS PE = 15.0
VTI PE = 25.1
So Grahamonomics would suggest heavily tilting to ex-US.
