I bought 10 KHC 35 strike calls that expire 7/17/20. The price closed on Friday at 35.01 I thought that option holders had to express their desire to the broker that they would want to execute before the end of expiration day if they finished In The Money and any options not 'sold to close' would expire worthless. I was wrong, OCC rules state that any options expiring in the money will be executed unless you specifically contact your broker 'Not To Execute'. (seems backwards) Monday morning, I was long 1000 shares KHC at 35 that I didn't want. Market price immediately moved to 34. I had the opportunity to gamble with losses that are way out of my risk parameters or lock in the $1000 loss. I sold the shares for a loss. I thought that pin risk was only associated with short options.
