Yeah, and nay. 365 makes sense talking interest. But so does 360. And then there's +1/+2. And more fancy stuff. It all depends on currency. So, 365 makes sense from a mentality of opportunity cost and accrual, given an ACT365 currency. And I wouldn't go with 252 because of OTC. I also would strongly advise against Sharpe ratios. From the title of the post - which I have my own problems with the post, but - "Why only buy when you can also sell?" really highlights why not to go with Sharpe, or Sortino, ratios: non-normal returns are the normal. Better with Omega, which is a concept already 20 years old but finance oddly sticks to the 80s.
