Identify and briefly discuss three criticisms of beta as used in the capital asset pricing model

The main issues concerning beta in a capital asset pricing model involve the lack of expertise that often accompanies the beta. Even with experience and standing in the industry, beta can still be wildly off-place even from the most respected of sources. Another big concern is that most beta uses an incomplete data set to assess a pricing model. Simulations are often a better way to collect accurate estimates.
