Black-Scholes model

The Black-Scholes model is the most commonly used formula when evaluating European call and put options. The equation was first published by economists Myron Scholes and the late Fisher Black in 1973. Later, Scholes and Robert Merton earned the Nobel Prize in Economics (1997) for the work done on the model and for its general contribution to the understanding of valuation of financial assets.

Market model

This relationship is sometimes called the single-index model. The market model says that the return on a security depends on the return on the market portfolio and the extent of the security's responsiveness as measured, by beta. In addition, the return will also depend on conditions that are unique to the firm. Graphically, the market model can be depicted as a line fitted to a plot of asset returns against returns on the market portfolio.

Jensen Model

Jensen's model proposes another risk adjusted performance measure. This measure was developed by Michael C. Jensen and is sometimes referred to as the Differential Return Method. This measure involves evaluation of the returns that the fund has generated vs. the returns actually expected out of the fund given the level of its systematic risk. The surplus between the two returns is called Alpha, which measures the performance of a fund compared with the actual returns over the period. Required re ...
