Can anyone explain why the " Dividend " changed the strike price of all the options ? That does not sound like a dividend but a distribution of capital !?
The div isn't really figured into the way an option is priced. The div payout can and does affect the "market price" which in turn affects the option price. That's how I understand it.
As I read about it, options are generally not repriced unless the dividend is >10% of the underlying stock price, so this must be a special case?
