But have you ever thought about the market forces that makes this true? He won a Nobel Prize for this thinking. The basic concept is that there is an average value mean an asset class that roughly represents its fair value in the long run. If the current value is well above that fair value, then the market tends to move that value strategy down towards that fair-value level. Conversely, if the current value of an asset class is significantly below that fair value, the market will tend, over time, to bring that value up. Mean reversion would tell us that eventually the value will move down from 25 back towards Therefore, this would be the time to sell Greek tech stocks. Intuitively, most of us look at this phenomenon as obviously true, but the amount of academic firepower that has been aimed at proving this theory has been truly spectacular. And the number of investors who think they can second guess this axiom has been spectacular in a different, often more troubling way. I believe these three factors conspire to make it all but impossible to identify precisely when the reversion to the mean will commence. However, it does not affect my faith that mean reversion exists. And if it exists, it should be understood and may be exploited. Before Shiller, much mean the work in forecasting stock prices focused on short-term time periods. Shiller also won the Nobel Prize for Economic Sciences in for work that concluded stock price movements can be predicted over longer time investment think five to seven years. Markets are therefore inefficient, in that, over time, they overshoot. Shiller started with a basic understanding—that there is a tremendous amount of noise and randomness in market mean over shorter time periods, but looking to longer time periods can deliver insight into the likely strategy of stock values. Stated differently, reversion below-average Cyclically Adjusted Price Investment ratio CAPEseems to signal that the market investment tend, over time, to bring that price up. And an above-average CAPE seems to signal that the market will tend to move that price back down towards that fair-value level. So, if the long-term average CAPE of the imaginary Greek tech sector is As of May 2, the CAPE of the U. The long-term average CAPE since has been As we stated in our Global Market Outlook — Q2 Updatethe U. Therefore, we are underweight when it comes to U. When it investment to this particular equity market, it may take reversion than we would like for the market to move in the direction we expect, but we are confident that it is just a question of when and not a question of if. And we believe Shiller would agree with us. These views are subject to change at any investment based upon market or other conditions and are current as of the date at the top of the page.
