The Greeks: What You Should Know Part 2
A lot of us know what the Greeks do individually but aren’t as certain on how they behave in relation to each other and the underlying asset. This write up will be done with the assumption you have read the previous post here:
Quick Example
Say John buys XYZ 100 1/15/21 Call (Buy-to-Open) for 1.00 and this contract has the following values:
Delta: 0.50 Gamma: 0.05 Theta: -0.02 Vega: 0.01
and the Current price of XYZ stock is $95.00.
This tells a lot but we will start with how Delta and Gamma work together:
(1) The Delta says that for every $1 move either up or down in price, will either decrease or increase the value of the option contract by 0.50 (e.g. $50). You will notice most option contracts are bought and measured for statistical purposes in the ranges of 0-0.20, .21-.40, .41-.60, .61-80, and .81-1.00.
(2) Then because Gamma is 0.05, for every change in Delta relative to a $1 movement in the underlying asset, The value of the option contract will increase by an additional 0.05 ($5) for every additional $1dollar change in the underlying assets price which would there create a correlated change in delta which is measured by gamma. So if the option contract for XYZ is 1.00 when the price of the underlying asset is $95 and then price moves up $1 dollar then the value of the contract becomes 1.50. (1.00 + 0.50) THEN, if the price moves an additional $1, Then the equation becomes, (1.50 + 0.50 + 0.05) = 2.05.
