A new Wharton study explains why stock returns aren’t random. Correlation neglect causes market overreaction, momentum, and reversals investors consistently misprice.

Abstract: To improve the computational efficiency of the time-dependent failure probability (TDFP) to system with dynamic loads, materials degeneration and other time-varying factors, a two-phase ...

Abstract: The synchronization in probability of reaction-diffusion neural networks (RDNNs) with stochastic sampling is studied in this article. By introducing a stochastic switching parameter, a new ...
