Topic: Why Getting Risk Right is Wrong
Abstract: Many investment professionals who use risk models make a common mistake. They assume that a risk model is working well if the amount of volatility realized by a particular asset or portfolio is consistent with what the model had predicted. They believe that volatility forecasts should be an unbiased estimator of subsequent realized volatility. In this presentation we will provide five different rationales as to why seemingly unbiased estimates of volatility are undesirable both statistically and economically. The implications of these arguments are that professional investors routinely take too much risk, back-tests and simulations fail to capture the true risk of strategies, and that evaluation of investment performance is biased toward perceiving luck as skill — leading to upward biased performance related compensation.
