Title:  Information and Inventories in High-Frequency Trading

Abstract:   We propose an equilibrium model for the short-term informational advantages crucial in high-frequency trading.
In this setting, risk-neutral insiders hold martingale inventories. In contrast, inventory aversion leads to autoregressive positions. These vanish in the continuous-time limit, while still yielding approximately the same returns. This illustrates how high-frequency trading allows to monetize information with very little inventory risk.

Joint work with Kevin Webster.
