Front Running

Front running is the illegal practice of a broker executing trades for their own account ahead of a large client order, using advance knowledge that the client's trade will likely move the market price.

Exam Tip

Front running = trading ahead of CLIENT orders. Insider trading = trading on COMPANY info. Both are illegal but different!

What is Front Running?

Front running occurs when a broker or trader uses advance knowledge of pending client orders to trade for their own benefit before executing the client's order. This allows them to profit from the expected price movement caused by the client's large trade.
