Market Potential Shapes Under Contrarian and Trend-Following Behavior

Summary

This article uses a market potential function to describe asset price movements, deriving two broad shapes from a free-energy minimization principle. When contrarian behavior dominates, the potential is U-shaped; when trend following is more prevalent, the potential is described as flat or logarithmic-like. The framework connects the shape of the potential with the balance of investor behaviors.

For empirical analysis, the authors use the Cyclically Adjusted Price-to-Earnings ratio to study long-term market data. They report historical changes in the US market’s potential and compare patterns across 12 countries, noting that Japan has a particularly flat potential. Recent US data appear more consistent with the trend-following form. The short description does not specify the estimation procedure or establish that these potential shapes can predict returns or support a profitable strategy.

Key ideas

• A market potential function is used to characterize asset price movements.
• Dominant contrarian behavior is associated with a U-shaped potential.
• Markets with more trend followers are associated with flat or logarithmic-like potentials.
• The empirical analysis uses the Cyclically Adjusted Price-to-Earnings ratio and long-term market data.
• The reported comparison covers the US and 12 countries, with Japan described as having a very flat potential.

In this article we discuss the distribution of asset price movements by the market potential function. From the principle of free energy minimization we analyze two different kinds of market potentials. We obtain a U-shaped potential when market reversion (i.e. contrarian investors) is dominant. On the other hand, if there are more trend followers, flat and logarithmic--like potentials appeared. By using the Cyclical Adjusted Price-to-Earning ratio, which is a common valuation tool, we empirically investigate the market data. By studying long term data we observe the historical change of the market potential of the US stock market. Recent US data shows that the market potential looks more likely as the trending followers' potential. Next, we compare the market potentials for 12 different countries. Though some countries have similar market potentials, there are specific examples like Japan which exhibits very flat potential.
