Optimal trading under proportional transaction costs
The theory of optimal trading under proportional transaction costs has been considered from a variety of perspectives. In this paper, Richard Martin shows that all results can be interpreted using a universal law through trading algorithm design
Optimal execution with a price limiter
Balancing the price uncertainty and price impact of large orders is an important issue for many market participants. While classical approaches lead to trading algorithms that are invariably price-path insensitive, in this article, Sebastian Jaimungal…
Portfolio construction and systematic trading with factor entropy pooling
Construction of large portfolios consistent with investors' views and stress test scenarios is a challenging task, considering the volume of information to be processed. Attilio Meucci, David Ardia and Marcello Colasante introduce a technique that…
