  • This thesis focuses on characterizing an optimal trading strategy for a large trader, who has to buy (or sell) a fixed large volume over a given time period. We propose a model in discrete time, based on VWAP (Volume Weighted Average Price). The objective is to minimize expected deviations between the trader's relative volumes and the market relative volumes at all times.

    By applying dynamic programming, we characterize the optimal strategy under three different assumptions on the intraday market volumes: i.i.d.~volumes, general independent volumes and independent Gamma distributed volumes. The optimal strategy under the last assumption is meaningful and explicit. For three exemplary Chinese stocks, we present its good data fit and illustrate the improved performance (reduced deviations to the market relative volumes) compared with the empirical strategy, which is one of the most popular and efficient VWAP strategies in the financial industry.
