We compute the correlations of the annual stock returns (1989-2008) of the Dow Jones companies with a) Rm; and with b) Rm; and find that the second correlation (assuming beta = 1 for all companies) is higher than the first one, on average, and for all companies except Caterpillar and General...

We calculate betas of 3,813 companies using 60 monthly returns each day of December 2001 and January 2002. The median (average) of the maximum beta divided by the minimum beta was 3.07 (15.7). The median of the percentage daily change (in absolute value) of the betas was 20%. Industry betas are...

It is a big mistake to use betas calculated from historical data to compute the required return to equity. It is a mistake for seven reasons: because betas calculated from historical data change considerably from one day to the next; because calculated betas depend very much on which stock index...

This paper deals with the CAPM-derived capital budgeting criterion, and in particular with Rubinstein’s (1973) criterion, according to which a project is profitable if the project rate of return is greater than the risk-adjusted cost of capital, where the latter depends on the project’s...

We prove that in a world without leverage cost the relationship between the levered beta ( L) and the unlevered beta ( u) is the No-costs-of-leverage formula: L = u + ( u - d) D (1 - T) / E. We also analyze 6 alternative valuation theories proposed in the literature to estimate the relationship...

En 2008 (hasta el 17 de septiembre), la rentabilidad de la bolsa española fue -25,9%, y hubo nueve empresas (entre 125) con rentabilidad positiva. Las 125 empresas destruyeron valor para sus accionistas por importe de 267 millardos de euros. Considerando conjuntamente 2007 y 2008 (hasta el 17...

La destrucción de valor para los accionistas de las 125 empresas españolas del mercado continuo en 2007 fue €15 millardos en 2007 y €89 millardos en los 17 primeros días de 2008. Telefónica fue la que más valor creó para sus accionistas en 2007, seguida de Arcelor, Iberdrola, Acciona y...

2004 was a good year for the shareholders of the companies in the Euro Stoxx 50: the shareholder value creation of these 50 companies was €42,880 million. It was not as good as 2003, however, when their value creation reached slightly over €160,000 million. The companies that created most...
