Getting rich quick with the Axiom of Choice

TL;DR

This paper explores theoretical get-rich-quick schemes based on the Axiom of Choice, demonstrating how traders could become infinitely wealthy under certain idealized conditions involving price path behaviors.

Contribution

It introduces novel theoretical schemes that leverage the Axiom of Choice to achieve infinite wealth in financial models with specific price path properties.

Findings

Infinite wealth can be achieved immediately after certain price path conditions.

The schemes rely on the Axiom of Choice, highlighting their non-constructive nature.

Practical applicability is limited due to the use of the Axiom of Choice.

Abstract

This paper proposes new get-rich-quick schemes that involve trading in a financial security with a non-degenerate price path. For simplicity the interest rate is assumed zero. If the price path is assumed continuous, the trader can become infinitely rich immediately after it becomes non-constant (if it ever does). If it is assumed positive, he can become infinitely rich immediately after reaching a point in time such that the variation of the log price is infinite in any right neighbourhood of that point (whereas reaching a point in time such that the variation of the log price is infinite in any left neighbourhood of that point is not sufficient). The practical value of these schemes is tempered by their use of the Axiom of Choice.
