The big take away from this for me wasn't that Markopolos is a genius, though he might be. It's that exposing the Madoff fraud wasn't complicated at all, its just that no one bothered to do any due diligence at all.
In a way it's really surprising that there haven't been more lawsuits over this between advisers and clients.
