Dividends are payment to you with your own money so they're not going to lower your cost by a penny. They're not a yours (a profit) until the stock rises by that amount.Quote from optionnew:
... in that case I plan the following, Exercise my 25 option before ex dividend, get the 1.40 dividend, next day sell the stock & buy the 25 call again for reduced price. In that case my cost will be reduced even more by the dividend, and my max risk (besides the 1 day I own the stock) will stay by 2.85 or less..
Make sense?
IOW, you get $1.40 dividend but the stock that you bot via exercise of your Jan 25c is now reduced by $1.40 and selling it books that loss. Then you buy back the original call and you''re back in the original position with a realized $1.40 loss and the same call that cost you $1.40 less. All you've achieved is slippage and a bunch of commissions.
