We are hoping this to be an easy and simple lesson to introduce options to you. By following Options Basics' articles, you should be able to understand options and how to utilize options to either profit or protect your stock.
This is the third part of "Meet the Greeks" if you are new to this, please click here: Delta, Gamma, Theta to catch up first!
Vega
Vega is the amount call and put prices will change, in theory, for a corresponding one-point change in implied volatility.
Vega does not have any effect on the intrinsic value of options; it only affects the "time value" of an option's price.
Normally, when implied volatility increases, the value of options will increase. This is because implied volatility going up suggests an increased range of potential movement for the stock.
Rho
Rho is the amount an option value will change in theory based on a 1% change in interest rates.
Rho is not as often talked about as the rest of the family.
For now, what we need to keep in mind is that if we are only trading shorter-term options, changing interest rates should not be affecting the value of your options much. But if you are trading longer-term options (what we call leaps), Rho might be one thing that we need to consider.
