Set forth below is the text of a comment that I recently posted to the discussion thread for another blog entry at this site:
“There’s value in calculating the safe withdrawal rate accurately before one hands in one’s resignation.”
There is also value in recognizing that you are <b>not</b> going to be able to calculate a <b>future</b> safe withdrawal rate accurately.
Any risk determination involves looking at what may happen in the future. That’s what the words mean.
It is not possible to know what withdrawal rate is going to SURVIVE in the future. I completely agree with that much. There’s always a range of possibilities. When the safe withdrawal rate is 1.6 percent (as it was in 2000), it is entirely possible that a withdrawal rate a good bit higher than that will survive. If a particular retiree wants to use a higher number as his personal withdrawal rate, that is of course fine. It is his choice.
But we shouldn’t be telling people that a withdrawal rate of 4 percent is “100 percent safe” at a time when the safe withdrawal rate is 1.6 percent and a 4 percent withdrawal has only a 30 percent chance of working out. Just because we do not know precisely what withdrawal rate is going to survive doesn’t justify reporting inaccurate numbers.
The safe withdrawal rate is defined as the highest withdrawal rate that would work in a worst-case scenario, the worst returns sequence that we have seen in the historical record. The error in the Buy-and-Hold studies is that they do not adjust for valuations. They report the SAME NUMBER as being safe at all valuation levels.
If the market were efficient, that would be correct. But Shiller showed that the market is NOT efficient in research that was published in 1981, that valuations affect long-term returns. When you take valuations into consideration, you see that a withdrawal rate that would work just fine at moderate valuation levels could easily produce a failed retirement for a retirement beginning at insanely high valuation levels. Whether that retirement will survive 30 years or not depends on what returns sequence happens to turn up. In many of the return sequences that we have seen in the past, it fails. In some, it succeeds. That’s not “100 percent safe.” That’s not what “100 percent safe” means.
The word games serve no good purpose, Evidence. A failed retirement is a serious life setback. We should be permitting honest posting re this subject at every site on the internet.
That’s my sincere take, in any event.

“There’s no news in knowing that 4 percent is not always safe.”
When the creator of the 4% rule says 4% is no longer safe, in the friggin Wall Street Journal, it’s huge news. Many times more people saw that article than Bernstein’s obscure twenty year old book. Thousands of times more people than saw Greaney’s study. Millions of times more than remember Greaney’s study (pretty much only you and Greaney.)
But to you, it’s all meh. Funny how you always have an excuse for taking no action yourself. You accept no personal responsibility for anything or anyone. It’s always “we have to…” meaning other people. When are you, Rob Bennett, going to do something more than make a note for yet another unseen ValueWalk repetition?
The Wall Street Journal had an article saying that the 4 percent rule is in error many years ago. I had a friend (Brian) at my last corporate job and we had discussed safe withdrawal rates when we worked there together. This was before I ever posted to Motley Fool. He was a Buy-and-Holder. He told me in a friendly way that I was nuts.
When he saw the article in the Wall Street Journal saying that I had been right all along, he gave me a call. I told him about the bans. He was shocked. He said that he was going to put up a post at the Bogleheads Forum telling the story. I told him that he would be banned if he did. He made a bet with me that he would not be banned. Of course he was banned within 30 seconds of advancing the post.
It’s not hard to calculate these numbers accurately, Miasma. If this were any other field of human endeavor, we could get all the errors corrected in 15 minutes. The problem is that in the field of stock investing people WANT to be told lies. If the experts report the numbers honestly and accurately, they lose their jobs. So they feel a lot of pressure to either pretend that they believe in the Buy-and-Hold stuff or to actually force themselves to believe it.
Will it change in the days following the next price crash? That’s the question.
Do you want to take a bet on whether Greaney corrects his study as a result of this latest Wall Street Journal article? I know which side of that bet I want to be on.
I’m happy that Bengen is telling at least some of the truth re this matter. But it is going to take more than one somewhat accurate article to get that CAPE value down to a reasonable level. People believe things that they hear over and over again. And the steady drumbeat of the Buy-and-Holders is not going to be drowned out by a single somewhat accurate article in the Wall Street Journal. If we opened every site to honest posting, we would see real change. One article will be ignored by all the people making money pushing the Buy-and-Hold garbage.
I am happy to see anything honest appear. But I have been doing this too long to believe that one article is going to change the world. If it was that easy, Bernstein’s book would have changed the world back in May 2002.
