In empirical studies of the CAPM, it is commonly assumed that, (a) the return to the value-weighted portfolio of all stocks is a reasonable proxy for the return on the market portfolio of all assets in the economy, and (b) betas of assets remain constant over time. Under these assumptions, Fama...

In this note we show how to use the binomial option pricing model to value executive stock options. Since executive stock options are tailor made and there is no standardized executive stock option, we used the stock options given to Mr. R. Kovacevich, CEO of Norwest Corporation as the example...

We develop a jackknife estimator for the conditional variance of a minimum-tracking- error-variance portfolio constructed using estimated covariances. We empirically evaluate the performance of our estimator using an optimal portfolio of 200 stocks that has the lowest tracking error with respect...

We conjecture that a mutual fund manager with superior stock selection ability is more likely to benefit from trading in stocks affected by information-events. Taking the probability of informed trading (PIN, Easley, Kiefer, O'Hara, and Paperman, 1996) to measure the amount of informed trading...

We measure the aggregate return to all equity investors in various funding rounds of a venture company with the founders' investments valued at their first-round pre-money valuations. We examine 17,242 ventures that had their first funding rounds during 1980 and 2006 and follow them till their...

We decompose the difference between a firm’s market and book values into two components: intangible assets that can be created by competing firms through SG&A/R&D expenditures, and the residual denoted as franchise value (FV). The estimated parameters in the model for creating intangible...
