David Morin jumped from Morgan Stanley to ABN Amro last week to join the firm's trading operations. At ABN he will be reporting to Catherine Yelverton, global head of secondary loan trading, who has been establishing the firm's secondary bank loan presence since the effort got underway last April. Morin had been working as an analyst in Morgan Stanley's credit department, but he began his stint on the loan desk as a trader's assistant to Robert Franz, who now works at Credit Suisse First Boston. Morin confirmed his arrival at ABN. A spokesman from Morgan Stanley confirmed his departure.
