1- Let’s start by defining what volatility is. It’s simply how often something moves up/down and how big these moves are. If something moves up/down a lot, it means volatility = high. Something that doesn’t move that much, it means volatility = low.
2- The best two candidates I found for this example are $GME to $WBA (since they are very close in price). Can you tell which one is more volatile?
3- I think you guessed it right, $GME is more volatile (what a chart!). Now let’s look at the options chain to see how volatility can make a big difference in the options prices.
4- This is a screenshot of the options chain of $WBA. We can see that:
-1: IV is 27.5% in the SEP 16 cycle (25DTE)
-2-3: ~29 Delta Short Strangle is going for $1 credit
-4: Margin requirement is CAD$ 761
5- Now let’s look at the $GME options chain.
We can see that:
-1: IV is 127.5% in the SEP 16 cycle (25DTE)
-2-3: ~29 Delta Short Strangle is going for $4.37 credit
-4: Margin requirement is CAD$ 7,139
6- Since $GME is much more volatile than $WBA, its options will be priced more expensively. Now look at the margin requirements. $GME is almost 10 times more than $WBA! Simply because it’s more volatile which means more risk.
7- Stay tuned for Part 2!
