Linear dynamic equilibrium correction mechanisms are shown to follow from the discretisation of continuous processes with steady-state solutions.

Purpose: The purpose of this paper is to revisit the numerical solutions of stochastic differential equations (SDEs). An important drawback when integrating SDEs numerically is the number of steps required to attain acceptable accuracy of convergence to the true solution....

Medium-term momentum, or the tendency of investment strategies based on buying past winning stocks while selling past losing stocks to maintain above normal performance over a period, has been a well-documented feature of stock returns in the US. We investigate the performance of momentum...
