I recently have read this thread: How to calculate Sharpe Ratio from $ returns?. I realised that the two methods given as an answer by the accepted post are not consistent, they give different results. I asked about this here: Which Sharpe ratio calculation is correct [closed]. But, this got closed because:
Basic financial questions are off-topic as they are assumed to be common knowledge for those studying or working in the field of quantitative finance.
Is there a way to ask about the inconsistency in that answer without being off-topic?
