Human beings’ decision-making processes are generally influenced by two typical cognitive biases: representativeness heuristic bias and conservatism bias. Previous studies found that the two cognitive biases cause investors to misreact to past stock earnings. This paper argues that the two...

The least-squares Monte Carlo method of Longstaff-Schwartz is utilized to construct the optimal exercise boundary (OXB) of an American put option when the underlying follows a geometric Brownian motion (GBM). The optimal exercise price at each time step is obtained by solving numerically the...

This paper studies the Level, Slope, and Curve factor model in the Chinese stock market. Empirical asset pricing tests reveal that the slope factor in the model represents either a reversal or a momentum effect for the Chinese stocks, and further tests on individual stocks demonstrate that the...

Portfolio selection is often faced with large noisy data sets of strongly correlated asset returns, and so is prone to unstable portfolio weights and serious estimation error. To attenuate these problems, this paper proposes a new latent factor model equipped with both a suitable robust...

This paper studies the negative relation between prospect value and stock return under anchoring effect. We show that high (low) prospect value stocks are overpriced (underpriced) in the Chinese stock market. However, this negative relation only exists in stocks far from the 52-week high, where...
