The single-index model (SIM) is a simple asset pricing model to measure both the risk and the return of a stock. The model has been developed by William Sharpe in 1963 and is commonly used in the finance industry. Mathematically the SIM is expressed as: α + ϵ {\displaystyle r_ {it}-r_ {f}=\alpha _ {i}+\beta _ {i} (r_ {mt}-r_ {f})+\epsilon ...
Hamada's equation. In corporate finance, Hamada’s equation is an equation used as a way to separate the financial risk of a levered firm from its business risk. The equation combines the Modigliani–Miller theorem with the capital asset pricing model. It is used to help determine the levered beta and, through this, the optimal capital ...
The average investor may not be familiar with what beta means, but they are no doubt fully aware of what it represents. Although there are different types of risk in the market, a stock's beta...
Security market line (SML) is the representation of the capital asset pricing model. It displays the expected rate of return of an individual security as a function of systematic, non-diversifiable risk. The risk of an individual risky security reflects the volatility of the return from the security rather than the return of the market portfolio.
Downside beta. In investing, downside beta is the beta that measures a stock's association with the overall stock market (risk) only on days when the market’s return is negative. Downside beta was first proposed by Roy 1952 [1] and then popularized in an investment book by Markowitz (1959).
