<prompt> Human: Im working on a project at work where I am comparing a portfolio return from 2008 against a benchmark. When the return is unadjusted it had a return of -25.66 compared to the benchmark of -43.48. However, when I adjust the return of the portfolio for risk I get a return of -51.95. I cant find an explanation online and Im trying to make sense of it. I may have done my math wrong, but I followed the formula my boss gave me and have double checked.  <response>: Because the idea here is that investments should payoff proportional to their risk.A riskier investment that performs equal to a less risky investment is a crappier investment as you took on more risk for the same reward.
