The only other times in our history when stock prices have been this high relative to earnings, a horrifying stock market crash has always followed. Will things be different for us this time? We shall see, but without a doubt this is what a pre-crash market looks like. This current bubble has been based on irrational euphoria that has been fueled by relentless central bank intervention, but now global central banks are removing the artificial life support in unison. Meanwhile, the real economy continues to stumble along very unevenly. This is the longest that the U.S. has ever gone without a year in which the economy grew by at least 3 percent, and many believe that the next recession is very close. Stock prices cannot stay completely disconnected from economic reality forever, and once the bubble bursts the pain is going to be unlike anything that we have ever seen before.
