  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.
