Abstract:
Momentum is a consistent phenomenon in financial data from the majority of markets around the globe. One prominent exception is the Japanese market, where returns from a momentum-investment strategy are nonexistent. The authors investigated international differences in the representativeness heuristic, which is one potential driver of momentum. After observing sequences of a random walk, subjects give probability estimates for the direction of the respective next change. The experiment was conducted in Japan and in Germany. For a subgroup of participants with lower cognitive abilities our results are perfectly in line with international momentum evidence.
