Query: Random walks that avoid their past convex hull   We introduce planar random walk conditioned to avoid its past convex hull,
and we show that it escapes at a positive limsup speed. Experimental results
show that fluctuations from a limiting direction are on the order of n^(3/4).
This behavior is also observed for the extremal investor, a natural financial
model related to the planar walk.
