Abstract: We introduce a new stochastic cost flow system for stock markets in which the probability distribution of the weighted average purchase price of a stock among all of its shareholders can be explicitly determined. The stochastic system is illustrated in three empirical applications. Through the empirical results, we demonstrate the impact of choosing cost flow assumptions on the reference purchase price estimates, we show the value of high-frequency financial data, and we advocate the need for the stochastic cost flow system when estimating the proportion of gains realized (PGR) and the proportion of losses realized (PLR) which are the most important measures for the disposition effect.
