We provide an entropy approach for measuring asymmetric comovement between the return on a single asset and the market …. Moreover, our approach also provides an entropy-based measure of downside asymmetric comovement. In the cross-section of stock …

instead the most likely demand distribution in the sense of maximum entropy. We then compare the performance of the maximum … entropy approach with minimax regret and Scarf's rule on large samples of randomly drawn demand distributions. We show that … the average performance of the maximum entropy approach is considerably better than either alternative, and more …
