Portfolio Management

By Saturday night, I will have finished two runs through all of the Schweser materials. And, for the next 28 days, I will be doing nothing but CFAI EOC questions, Schweser questions, Schweser Key Concepts and their question bank. But, I have one question. I understand why most of the CFAI LOS are included, but I do not understand why we need to know all those endless formulae in Portfolio Management when everything in our business is computerized now. Really . . . . . the variance of an asset is equal to beta squared times the variance of the market plus the variance of the error term? I guess there are a few people on the planet who need to know this but, as they say, they are way out in the tail beyond the third standard deviation. I cannot wait to put this behind me.
