Are Financial derivatives actual derivatives (rate of change of the rate of change) or differences (how to put this ... rate of/actual separation distance?)
For instance, the simplest derivatives are puts or calls, i.e. the right to buy or sell a share (or bond, or whatever) at a given price at a given date. In the long run, we're all dead. John Maynard Keynes
Oh, I see ... "bullshit" was already taken. ;-)
