We introduce a trade strategy representation theorem for performance measurement and portable alpha in high fre-quency trading, by embedding a robust trading algorithm that describe portfolio manager ...
Computing Quantiles in Regime-Switching Jump-Diffusions with Application to Optimal Risk Management: a Fourier Transform Approach

2012/9/14
In this paper we consider the problem of calculating the quantiles of a risky position,the dynamic of which is described as a continuous time regime-switching jump-diffusion, by using Fourier Transfor...
Inventory Management with Partially Observed Nonstationary Demand
Inventory management Markov modulated Poisson process hidden Markov model partially observable demand censored demand.

We consider a continuous-time model for inventory management with Markov mod-ulated non-stationary demands. We introduce active learning by assuming that the state of the world is unobserved and must ...
