The Market Portfolio May Be Mean-variance Efficient after All
Testing the CAPM boils down to testing the mean/variance efficiency of the market portfolio. Numerous studies have examined the mean/variance efficiency of various market proxies by employing sample parameters, and have concluded that these proxies are inefficient. Shrinkage methods do not seem to help. These findings cast doubt about one of the cornerstones of modern finance. This study adopts...
متن کاملCuprate Superconductors May Be Conventional After All
C opper oxide superconductors, or “cuprates,” are the record holders for the highest critical temperature (Tc = 134 K) at ambient pressure. Among many applications, they might one day be used to make the tens of kilometers of cables that generate accelerating magnetic fields at CERN’s Large Hadron Collider. The origin of high-Tc superconductivity in cuprates, however, remains a major unsolved p...
متن کاملRisk Seekers May Be Antisocial After All
Undergraduates were given a battery of psychological tests to gauge their degree of antisocial personality traits (psychopathy, Machiavellianism and nihilism). The students also responded to questionnaires to assess their attitudes toward risk and
متن کاملEfficient Portfolio Selection in a Large Market†
Recent empirical studies show that the estimated Markowitz mean-variance portfolios oftentimes perform rather poorly when there are more than several assets in the investment universe. In this article, we argue that such disappointing performance can be largely attributed to the estimation error incurred in sample mean-variance portfolios, and therefore could be improved by utilizing more effic...
متن کاملProductively Lindelöf spaces may all be D
We give easy proofs that a) the Continuum Hypothesis implies that if the product of X with every Lindelöf space is Lindelöf, then X is a D-space, and b) Borel’s Conjecture implies every Rothberger space is Hurewicz.
