Based on proprietary S&P 500 futures trading records of professional traders, I investigate the loss-aversion, break-even, lock-in, and house-money effects. Unlike previous studies that find evidence of either loss aversion or the house-money effect, I find no consistent evidence supporting the impact of behavioral biases on professional traders. Furthermore, I examine the relation between trading experience and behavioral biases. Unlike for individual traders, I found no link between trading experience and behavioral biases among professional traders.
