What is hedging?

So is diversification a type of hedging? Or is hedging a specific type of diversification? Or are hedging and diversification different things?I tend to think of hedging as something you do to protect against a specific known risk (I know that interest rates can change, but I want the credit spread, so I'll buy this type of credit, but my purchases will include a hedge to remove the interest rate risk).I tend to think of diversification as something you do to protect against unknown risks, or risks that cannot be specifically hedged (should I be worried about earthquakes in California, riots in Basra, the CEO being hit by a truck, or something else I haven't thought of - so better have lots of different things in my portfolio).I'm sure there is a relationship between hedging and diversification, but I'm having trouble specifying it... any thoughts here?

From a trading point of view, hedging and speculating are one and the same. You can never fully hedge an exotic options book. Even if you could, you wouldn't do it. As a trader, you are forced to weigh certain risks versus others. What you end up doing is leaving the "good" risks, and selling the "bad" risks, depending on your view of the market. Some call it hedging, but you might as well call it speculation. There is really no difference.
