My strategy is pretty simple. It wouldn't take an advanced degree to figure it out. However, it is very emotionally difficult as I can go years without taking a trade, and then find myself fully invested in just a few or even 1 stock. Most people don't have that much patience or that much conviction.
If you don't know your edge, you probably don't have one. My edge against the algorithms and PhD's is that most don't have the emotional makeup to do what I do.
