Rho
Swing Trading, A Scientific Approach . Wall street Journal!
The rho will give you an estimate for every 1 percentage point of movement in the interest rate. If the rho is .03 then the option should move up $.03 if the interest rate goes up 1 point and it will move down $.03 if the interest rate moves down 1 point. Most professional stock traders do not pay too much attention to the this greek. The interest rate is fairly stable. Also it does not affect the price of an option too much. Weather you take this greek under consideration it is an important concept to understand.
