Abstract:

We present an in nite-horizon insider trading model in which the order ow of liquidity traders is a linear function of the time interval and contains persistent and transient components. Price impact depends on the order ow rate. Although the risk-neutral insider is super impatient, the asset price is not fully revealing, even in the continuous-time limit. When the time interval is short, following a negative persistent liquidity shock, the price either rises or drops (like a negative spike) rapidly and then rises. The duration of the rst phase is roughly proportional to the time interval. Price spikes are more likely to occur when the amount of the transient component of liquidity trading is large, private fundamental information is long-term oriented, and persistent liquidity orders are executed quickly, wherein insider trading destabilizes the price and thus makes it less resilient.
