Forgive me for asking this question again, but I realize I did not post it as a new thread. I often see calculations involving Risk, but I've never seen an explanation of how a value for risk itself is derived. Can someone explain how Risk is calculated?
Your question is too broad. Can you narrow it down to be more specific. What asset class are we discussing? What risk are we being asked to calculate? In "general" there are two types of risk. Market risk (beta) and company specific risk (alpha). Is this what you're asking?
