Sharpe Ratio Before Tax Return

In Exam 1 Schweser book 2 problem 1 C…we are calculating roys safety first but you have to solve for sharpe first. the data gives the after tax expected return but they convert to a before tax return before inputting the expected return into sharpe. so is the expected return in sharpe or roys supposed to be before tax expected return or after? i could not find in any of the textbook where they talked about sharpe using either or.

i always assumed it was gross of tax but they dont often ask you to work in the tax component

I assume it’s before tax, because I have never heard of a “risk-free rate after-tax.”

check out the exam 1 schweser book 2 problem 1 c. i had never seen anything like that and calc’d the sharpe based on the given after tax return. no clue why would convert it to before tax.

Hey guys, Schweser has made a correction to that particular question. Basically, there’s no need to gross up the after tax returns.
