Security Market Line (SML) is the line that results, when we plot predicted returns and betas coefficients, is clearly of some significance, so it is useful to provide it with a name.
The Security market line (SML) is "a positively sloped straight line displaying the relationship between expected return and beta" (Whitehurst, 2003).
This new connection becomes obvious if we restore the CML to type what is known as the Security Market Line (SML).
This is the extended equilibrium market equation and the security market line of the classical capital asset pricing model of Merton (1987) in continuous time.
This equation is a natural generalization of the results in the standard security market line and the results in Merton's (1987) CAPMI.
Risks associated with the range of R&D returns asserted by Gibbons can be estimated using the Security Market Line (SML).
