The beta () of an investment security (i.e., a stock) is a measurement of its volatility of returns relative to the entire market. Typically you will create three scenarios, optimistic, base and pessimistic. Levered beta (equity beta) is a measurement that compares the volatility of returns of a companys stock against those of the broader market. A security's beta is computed by dividing the product of the covariance of the security's returns and the market's returns by thevarianceof the market's returns over a specified period, using this formula: In cored plaques we measured an increase of N-terminal truncations of approximately 20% between Braak stages IV to VI.
