### Comment:
IV is implied volatility, basically the chance it has to move drastically. If it's high there's greater risk and reward (lolz), if its low it wont *likely* have drastic movement. The price can go up because of the chance something big happens with the share price. Gambling on weekly FDs before earnings is a great example of when you should invest your life savings into a high IV option.
