We report on six large-scale financial markets experiments that were designed to test two of the most basic propositions of modern asset pricing theory, namely, that the interaction between risk averse agents in a competitive market leads to equilibration, and that, in equilibrium, risk premia are solely determined by covariance with aggregate risk. We designed the experiments within the framew...

Testing CAPM with a Large Number of Assets This paper is concerned with testing the time series implications of the capital asset pricing model (CAPM) due to Sharpe (1964) and Lintner (1965), when the number of securities, N, is large relative to the time dimension, T, of the return series. In the case of cross-sectionally correlated errors, using a threshold estimator of the average squares of...

The negative CAPM alphas of high-beta and high-variance stocks are attributable to an unaccounted factor in the CAPM. We use eight seemingly unrelated anomalies construct a composite spirit optimal orthogonal portfolio (FOP). Accounting for FOP re-establishes positive relation between beta average returns time series regressions as well cross-sectional explains stocks. To analyze economic drive...

Traditional finance theory based on the assumptions of symmetric information and perfect and competitive markets has provided many important insights. These include the Modigliani and Miller Theorems, the CAPM, the Efficient Markets Hypothesis and continuous time finance. However, many empirical phenomena are difficult to reconcile with this traditional framework. Game theoretic techniques have...

Since the inception of Capital Asset Pricing Model (CAPM), numerous empirical studies have been conducted to test its effectiveness. However, there are several disputes surrounding CAPM model's implementation and study in Chinese securities market. This paper first describes significance model testing validity Then summarizes 11 papers that include using data from Shanghai Shenzhen stock exchan...
