Roger Farley, one of my best former students from many moons ago, was a graduate student in writing seminars (where he was working with the famous professor John Barth) at The Johns Hopkins University when he took my course in commodity and foreign exchange trading.
Roger addressed my students yesterday at the Institute for Applied Economics, Global Health, and the Study of Business Enterprise in our usual Friday seminar. It was a brilliant performance. Farley has a distinguished trading record and is now writing the attached weekly newsletter-- something I highly recommend you follow.
