Which part of the variance calculation requires subjective probabilities? It can be calculated very easily if you have the daily returns of a stock, the market, industry, etc. The same can be done for correlation coefficients.
From my understanding, the only difference in calculating betas depends on if you take daily, monthly, yearly, or hourly returns. Other than that, isn't it calculated the exact same way no matter what? |
