From a reader:
Michael, I am interested in learning about trend trading and read a lot of amazing things about the turtles. However, I tried to find something online about Richard and his staggering losses during the late 80’s and 90’s. Maybe I am missing something here, but is there a reason that his system was not working after a certain period? Is there an article or resource you could point me to? Thank you.
Your premise/predicate is off. You got it correct that Dennis had losses, but you need to see the whole picture. The full story of these issues is here.
Lesson? The Internet is a limited source of knowledge.
