After several weeks of quiet in the markets, economy and geopolitics, last week exploded with excitement and volatility, seeing commodities tumble and large-cap stocks end strong. It started with news that Seal Team Six had taken out Osama bin Laden in Pakistan and ended with silver crashing 26%, crude oil plunging 15%, and corn down 6.5%. Determining how these events are connected will provide historians with rich material to ponder in years to come. It is very rare to see the prices of unrelated commodities plummet like that in a single week. It's an event that might occur once in a generation. Now you can say you were there.
