When will the beta charts in finance be an improvement over the classic ones, rather than a poor substitute?

Question

Look at SWRG for 8/16 at the end of the day on both. The closing price was 10.89, but you'd never know it from the beta chart, even a day later when there's no excuse whatsoever for an incomplete chart!

Answer 1

Two questions. First, why would anyone own this company? Having looked at the fundamentals, I am not sure it will survive as a going concern.

Second, beta charts will never occur. Beta uses the partial derivative, estimated by regression, but cannot actually know the partial. As a partial, it also strongly fails as an estimator. Since regression is the basis of beta and the assumptions of the regression are strongly violated, the measure itself has no meaning.

Beta is going to disappear from finance.
