The CAPM formula is given by: E(ri)=rf+βf(E(rm)−rf) E(ri) i rf βi beta i i E(rm) Using CAPM, you can calculate the expected return for a given asset by estimating its beta from past performance, the current risk-free (or low-risk) interest rate, and an estimate of th...
You can think of the formula as predicting a security's behavior as a function of beta: CAPM says that if you know a security's beta then you know the value of r that investors expect it to have. Naturally, somebody has to verify that this simple relationship actually holds true in ...

he just buys 120 stocks and holds them. So his breadth is 120. Suppose a Hedge fund has developed a computer algorithm for stock trading that is 1/1000 as smart as Warren Buffet. Then if you do the math with this formula it comes out that the Hedge fund needs to trade 120,000,000...
Take the value for expected asset return found in step two and the actual observed return of that asset and solve for alpha using the formula: alpha = return on investment – expected return on investment. An alpha greater than zero means the investment outperformed its expected return. ...
Section 3 presents the CAPM with CDaR in the case of a single sample-path and evaluates βDD for hedge fund indices from the HFRX database. It also introduces the drawdown alpha (similar to the classical alpha) as asset excess return compared to the CAPM prediction and evaluates drawdown ...
Using the CAPM formula, what return should a client expect from security that returned 10% with a standard deviation of 6%, a beta of 1.5, when the overall market return has been 8%, and the risk-free Assume that the CAPM holds...
