Set forth below is the text of a comment that was recently posted to another blog entry at this site:
I sincerely believe you have a mental illness.
I don’t believe that you have a mental illness, Anonymous. But I do believe that you suffer from irrational exuberance. It’s a form of addiction. I believe that the primary focus of investment advice should be to help people avoid irrational exuberance and to recover from it once they fall prey to it.

My net worth is hitting another all-time high today. I’m happy, but I also know it could fall by some great number like 50%. What’s irrational about this? Irrational is doing the same thing every day for over 20 years and getting the same result every time but expecting a different result.
First of all, it could fall by a lot more than 50 percent. The CAPE value would have to fall by 50 percent just to get to fair-value levels. To suggest that a 50 percent price drop would be a bit of a surprise is to suggest that stocks can be priced higher than fair-value levels for long stretches of time but never go to levels below fair value. Really?
We have just lived through a 28-year time-period in which prices were far above fair-value levels. We shouldn’t consider it strange to see the irrational depression that inevitably follows irrational exuberance get just as much out of control as the irrational exuberance that brought it on. What do you think it would do to our economic system for us to see 28 years in which prices are far below faor-value levels, that is, far below where they would be after a 50 percent drop from today’s levels.
I think it makes more sense to be satisfied with the 6.5 percent real return we get from economic growth. The irrational exuberance garbage possesses zero appeal to me.
Research-based strategies haven;t just been working for 20 years. They have been working for 150 years. The entire point of doing research is to find out what works. Banning the discussion of what the peer-reviewed research shows works is irrational. Buy-and-Hold is an emotion-based approach. Not this boy, you know?

The person who bought stocks before the 1929 crash and then held them made out better in the long run than the person who held no stocks at all. That was a 90% drop.
The person who followed a strategy rooted in Robert Shiller’s Nobel-prize-winning research lowered his stock allocation when stock prices reached the insane highs that led to the 1929 Buy-and-Hold Crisis and then increased them again when prices fell to reasonable levels. That person earned far higher long-term returns at greatly reduced risk compared to the Buy-and-Holder.
It is impossible for the rational human mind to imagine a circumstance in which exercising price discipline when buying stocks could ever produced poor long-term results. Hence the Nobel prize! Hence my belief that we need to open every internet site to honest posting re the peer-reviewed research, without a single exception.
My best wishes.

The bottom of the bear market that started in 1929 took years. Who managed to wait sit on his cash (literally, as the banks failed) and then invest at the most opportune time?
No one can know when prices are going to shift. The guessing-game approach to market timing doesn’t work, according to all the evidence that I have seen. The Buy-and-Holders got this one right. They provided us all with a powerful insight by pointing out the dangers of the guessing-game approach to market timing.
Valuation-Informed Indexing doesn’t involve any guessing games. It’s just Staying the Course in a meaningful way. The aim is to keep your risk profile constant over time. When prices increase so much that your risk profile is out of whack, you lower your stock allocation to the extent needed to correct the problem. When prices decrease so much that your risk profile is out of whack, you increase your stock allocation to the extent needed. It’s Stay the Course investing. It always works. It’s not possible for the rational human mind to imagine a circumstance in which it would not work.
Research is a plus. Research helps us learn. Research helps us to rein in our Get Rich Quick/Buy-and-Hold impulses.
