If you don't understand an investment your about to make, then you are probably wise to avoid it in the first place. Apparently the folks at JP Morgan didn't learn in 2008 that "financial engineering" is risky business. Any time you hedge against risk using layers of "instruments", you are engaged in gambling. JP Morgan's bet went bad and it will be some time (if ever) that we understand what really happened.
Instead, you might be better just sticking to one of the basic tenets of investing - transparency! Understand what is under the hood of the products you invest in. If you are not going to open the hood, then it might be in your best interest to hire someone who will.
