The week's question
In March 2025, in the thread "Re: OT, out", Umm asked the members: "Do you think it is because America is made up of magical soil that makes businesses based in America magically profitable?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

The 5 rules he describes are:
Portfolio management rule


This rule is garbage. When I started with G-K in 2006, I first wrote down the exact steps to do G-K and plot out the money flows. Specifically I needed to put the rules into a spreadsheet. I was unable to come up with the steps that would do this one. I asked the question on a couple of money/retirement boards.

A number of people responded, saying some version of "Simple. You do this and this and ..... uuuuh ... hmmm .... gee I have no idea how you would do this."

So I decided that Mssrs. Guyton and Klinger just put that rule in for looks. Because nearly "everybody" thinks you need to have a cash bucket.

The other 4 rules are easy to put in a spreadsheet.

Since 2006, in my portfolio the WR rule has fired 5 times, the CPR 2 times, and the PR once.
