Minimum acceptable return on an investment

Just wondering how to calculate minimun acceptable return on an investment given its risk (Standard Deviation)?

dont recall that definition from the curriculum but I would suspect you would look to the financial markets for this info and look at bond rates. essentially what interest rate could you earn on bonds for your standard deviation (or a similar risk free instrument)

This is just how I’d approach it in practice. I looked over my schweser quick sheet and didn’t see this on it
