This paper expands on a procedure to arbitrage mispriced assets against the benchmark provided by the Security Market Line, but using only separation portfolios to put up a feasible portfolio with the same beta as the mispriced asset and the least total risk among other alternative portfolios....

In this note we present a simple method to include the no-arbitrage condition into the derivation of conditional densities using the principle of maximum entropy. For the case of identically and independently distributed returns, we easily derive that the whole process estimated that way is...

This paper investigates the limit properties of mean-variance (mv) and arbitrage pricing (ap) trading strategies using a general dynamic factor model, as the number of assets diverge to infinity. It extends the results obtained in the literature for the exact pricing case to two other cases of...
