Subject: Re: $840 Billion Market Cap
Yah, options are VOLATILE!! Couple days ago I sold the BRK Jun 400 call for 9.01, the next day it dropped to 7.07 -- I almost bought it back for 27% 1 day gain but didn't.
Today it hit 10.73, closed at 9.80.

Maybe you're thinking about them wrong : )

I find it is most useful to think of an option contract as merely one WAY to own, or sell, the underlying stock. I always assume assignment.

A 1% move in the stock price is pretty trivial, and that would be a move of $3.80.
Your option contract price changed by less than $2, not much in the grand scheme of things.
