Testing for alpha in linear factor pricing podels with a large number of securities
Pesaran, M. Hashem; Yamagata, Takashi - 2017
This paper proposes a novel test of zero pricing errors for the linear factor pricing model when the number of securities, N, can be large relative to the time dimension, T, of the return series. The test is based on Student t tests of individual securities and has a number of advantages over...

Optimality and diversifiability of mean variance and arbitrage pricing portfolios
Pesaran, M. Hashem; Zaffaroni, Paolo - 2009
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...
