The movie on Netflix, The Big Short was a nice example of edge trading. They spotted a structural flaw and positioned trades to take advantage of it. I had to watch it a couple of times to get past the drama and see the concept. The movie overstated how "in the pocket" the rating agencies were. In the real world the cdo ratings were lifted by buying insurance from companies like AIG to reduce default risk. A poor bond rating could gain double A status just by buying enough insurance to reduce the default risk by 1 or 2 percent. CDO's have been created for car loans and credit cards as well. I imagine some hedge funds are trying to short car loan cdo's now and we'll doubtless here of huge performance in the next year or so.
If anyone has trouble understanding the complexity in the movie I recommend watching The Flaw on Amazon Prime. It also helps to understand how this edge is still in existence today.
I mention this because too many traders are dependent on Technical Analysis to trade. Edges are the bread and butter of trading. The more of them you can use, the better your results in trading will be.
Good post and a celebrity appearance!
