Controlling the speed and direction of trades becomes increasingly important to algorithmic trading desks. Brian Bulthuis, Julio Concha, Tim Leung and Brian Ward propose a new optimal execution algorithm with both limit and market orders. An optimal strategy is derived analytically and...

We study the optimal execution of market and limit orders with permanent and temporary price impacts as well as uncertainty in the filling of limit orders. Our continuous-time model incorporates a trade speed limiter and a trader director to provide better control on the trading rates. We...

This paper examines the main drivers of the returns of gold miner stocks and ETFs during 2006-2017. We solve a combined optimal control and stopping problem to demonstrate that gold miner equities behave like real options on gold. Inspired by our proposed model, we construct a method to...

We study a series of static and dynamic portfolios of VIX futures and their effectiveness to track the VIX index. We derive each portfolio using optimization methods, and evaluate its tracking performance from both empirical and theoretical perspectives. Among our results, we show that static...

This paper studies the empirical tracking performance of leveraged ETFs on gold, and their price relationships with gold spot and futures. For tracking the gold spot, we find that our optimized portfolios with short-term gold futures are highly effective in replicating prices. The market-traded...
