Gekko,
Don't you know that Futures & Derivatives represent only one other categories of markets? If there were only those two, wouldn't the Financial Times, Barrons, Business Week, Investors Business Daily, & Wall Stree Journal contain far fewer pages? It stretchs credibility that you can't concieve of there being more investment vehicle "groupings" than just those two.
Oh well, maybe you are just a novice. La la la la la....
