Set forth below is the text of a comment that I recently posted to the discussion thread for another blog entry at this site:
Why haven’t things worked out the way you said they would? Why didn’t we see the big crash?
This is a big question. If Shiller’s Nobel-prize-winning research is legitimate research (I believe that it is), then this is a question that we should be examining at every investing site on the internet on a daily basis. If Shiller is right, then when stocks are priced as they are today, half of our portfolio value has no economic substance to it and is comprised of nothing more than irrational exuberance. The question of when prices will return to reasonable levels is huge. Knowing that tells us when hundreds of thousands of businesses will fail and when millions of retirements will fail and when we will see a spike in political frictions and on and on. So we all need to come to a better understanding of why the crash has been delayed (this is the longest time-period in U.S. history in which prices have remained at super high levels).
The key to understanding this is to avoid falling into the trap of seeking economic explanations of what has happened. That’s pre-Shiller thinking. What Shiller showed is that much of what happens in the stock market has no economic foundation — it is rooted in investor mood swings. So we need to focus on investor psychology. What is different about investor psychology today that we have been able to keep stock prices up at super high levels for longer than ever before? That is what you are asking.
A book could be written on this question. But I think that the basic thing that is going on is that people are scared. An irony of economic progress is that, the richer people are, the more vulnerable they are to setbacks. Lots of people are okay with how they are living today. But they feel that they are on the edge. They do not feel secure. So they cannot even imagine how it would feel to experience a loss of 50 percent of their life savings, which is what we would see if today’s irrational exuberance were to disappear, as it must if the market is to continue to function.
So they block the thought of those losses out of their mind. So long as people do not think about the losses, they cannot take steps to avoid them. So people are not lowering their stock allocations. Which is what we would need to see for prices to come down. We are scared and paralyzed. If we were to act in our own best interests, we would lower our stock allocations. Doing that would bring on the price crash that we fear. So we don’t act. We cross our fingers and hope for the best.
I don’t favor this approach. I believe that it would be better to face our problems frankly. Then we could manage a price drop and keep it from getting out of control. But I am not seeing any signs that we are going to manage things. We are going to put off the day of reckoning just as long as we can. Then when it comes, we will panic. Not ideal. But panic is a natural result when we set things up so that the huge price crash comes as a surprise.
Think about an alcoholic, Anonymous. Say that at age 30 all bis friends predict that his life will crash by ago 40. But it doesn’t happen. The guy is very talented and has a will of steel. He makes it to 54. He still is in great danger of seeing his life fall apart but it hasn’t happened yet. To what would you attribute the long delay in his coming to terms with his alcoholism? I would say it is fear. The longer his addiction remains in place, the harder it is for him to fix his marriage and his career and his friendships and his health and his financial affairs. It doesn’t get easier over time, it gets harder.
But of course sooner or later he has to set things right. While it become harder to fact the addiction as time passes, it also become more imperative that the job be completed. We are deep into a price addiction today. It has gone on so long that it has become very, very hard even to think about what it would mean to permit prices to return to reasonable levels. But we know somewhere inside that we have no choice but to let this happen. But as of today, the thought is — put it off, put it off, put it off. It’s been like that for a long time now.
I hope that that helps at least a tiny bit.
