this is a trick question ??
if the general trend, (whether you believe such a thing exists or not
), is up, I would be more inclined to seek out "cheap" (low-risk) longs ( longer-term chart up, look for shorter-term chart down, but turning up ), and the opposite for seeking out "cheap" (low-risk) shorts.
(I would say "pullback", but as yet, I am unable to mathematically prove its existence.)
my predeliction for shorts or longs would be determined by the market direction, so would have no real preference.
however, your question reminds of a "fact" that the market falls more sharply than it rises.
something like it falls 3 times faster than it rises.
wonder if any traders have experience of making money "faster" on shorts than longs ?
