My old mucker David Byne has left the option pricing specialist SuperDerivatives for a new role at Credit Suisse in AES FX sales. The bank says his hire is representative of its push to roll out its highly regarded advanced execution strategies (AES), or algos as they are known, across asset classes. Byne’s departure from SuperDerivatives is amicable, although no doubt the company will miss him. He is due to start at Credit Suisse in mid-March and will report to Jonathan Wykes.
