also to the op, this reminds me of a clasic dilemma: Assuming both have the same expected value which strategy would you choose, the one with small frequent profits and big rare losses or the one with big rare profits and small frequent losses?
it depends on how big the rare big losses are in the first instance. because it could mean that one big loss wipes out months of gains.. i would be more interested in the second instance, there isnt that risk of the big loss .. there is also a middle ground by the way not just the 2 extremes you mentioned..
