Gambling the World Away: Myopic Investors

Bernhard K Meister

Papers from arXiv.org

Abstract: Myopic investors are locally rational decision-makers but globally irrational. Their suboptimal portfolios lag the market. As a consequence, other market participants are provided with profit opportunities. Not subterfuge but constrained optimisation leads to disparities. Four overlapping examples are given. The first case centres on the difference between local and global optimisers and their respective Kelly fractions, the second on isolated versus combined optimisation, the third on the distinction between qualitative and quantitative investor, the fourth on the non-commutative nature of information and the resulting asymmetries.
