distribution is extremely fat-tailed. SD is not very helpful.

risk is the input, while reward is the output

it is just like the input-output analysis

I recommend that using one variable as risk/input, and another as reward/ouput.

if you use more variables for both sides, it will be difficult to rank the scenarios. or maybe some methods like data envelope method will be used.

I also used a sort of modified 'coefficient of variation' to look at risk adjusted return. Regardless of the distribution I think this is the most appropriate style of approach.
