It's all about probability IMO.
I've experienced 1 losing setup in 2013 and none in 2014 so far. With avg +2% monthly growth, I can live with 6% max DD.
Since Jan 25th when I applied new risk measures, I have avg monthly growth vs DD ratio around 1:1.
But if you know about any investment product with better stats (avg growth vs maxDD), good for you. Maybe you could share with us
