I had the opportunity to visit with one of the best trend followers today. Living in the Chicago area, he works from his home office with a small staff. He might not be the largest trader (he does trade many hundreds of millions), but his performance is top notch. He is also just a fun and interesting person. No quant jock stiff here.
This trader, unlike some trend followers, has plenty of fundamental opinions. He reads voraciously on the markets and is not afraid to wear his emotions or concerns on his sleeve. This is precisely why he relies on a trading model.
He knows he can be volatile. He knows he can be emotional. And he is bright enough to never let those personal views interrupt his trading system. In his world, his well thought out automated trading strategy keeps it all in check.
