I'll take the liberty of posting some fun facts: 1) There is one commodity that is banned by law from trading (futures, forwards, derivatives). Which one? Why? What has the result been? Why did it result in this? 2) A "puzzle" has long persisted in economics/finance and many ave tried to explain it. Interestingly, due to the past few years, this "puzzle" actually no longer exist. Which puzzle am I talking about? Do you think it is a real puzzle/phenomenon? David, Suzanne: Feel free to move post to more appropriate forum section.
