SOES Bandit

A trader who uses the Small Order Execution System (SOES) on NASDAQ to manipulate prices. The SOES bandit conducts a small transaction on a security in order to affect the price, and then executes a larger transaction to take advantage of the price inefficiency. This is a form of insider trading, as the broker executing the order knows something about the market's probable movement that other market participants do not know. An SOES bandit is also simply called a bandit.
