Set forth below is the text of a comment that I recently posted to the discussion thread for another blog entry at this site:
“The title is “Irrational Exuberance.”
What exact words in the book talk about death threats, job threats, jury trials, prison sentences and $500 million windfalls?
Shiller was awarded a Nobel prize because he published research that discredited the Efficient Market Theory. If the market were efficient, stock price changes would be caused by economic developments and would reflect reality. He showed that, when the market is overpriced, it is irrational exuberance that causes price gains and that those gains thus cannot be counted on to finance a retirement.
All of the things that you refer to in your post are things that follow if a person points out what Shiller’s research shows in a community frequented by a significant number of Buy-and-Holders. It hurts the feelings of Buy-and-Holders for them to hear that they made a mistake in thinking that the market is efficient and that it is not necessary for them to exercise price discipline when buying stocks.
I don’t do it to hurt their feelings. I do it because people need to have accurate numbers to plan their retirements. If there were a way to give accurate numbers without hurting the feelings of the Buy-and-Holders, I would make use of it. But there isn’t. This is the risk that goes with the use of any research-based strategy. New research is published all the time. When we learn new things, we need to update our understanding of a subject. We need to acknowledge that we didn’t always know it all.
I am grateful for all that the Buy-and-Holders taught us. They of course got many things right. But not the efficient market thing. Not according to the last 37 years of peer-reviewed research in this field. I think that the Buy-and-Holders have hurt themselves and many others by failing to acknowledge the mistake they made re that one. The safe withdrawal rate is not always 4 percent. It is a number that changes with changes in valuation levels.
That’s my sincere take re these terribly important matters, in any event.
I naturally wish you all the best that this life has to offer a person, Anonymous.
