For most of us, including me, this is about as useful as the bicycle equations. However, as interpreted by computers and programmable calculators, it launched the trillion-dollar market in derivative securities. Furthermore, it is easy to gain a seat of the pants understanding of options. This in turn can allow you to actually benefit from uncertainty, rather than fear it.

One of the most basic derivatives is the ...
