Marco, you are right about slippage. I am not sure I follow about 56%. I do unwind the shares (already did some) and earn total $0.5-1.5/share this way including commissions, unless I wait till January, where I will earn full dividend. It's very unlikely that AAPL will drop below 400 until Jan expiration, but if it did, I would hold on to it then. We'll see. I bought shares/wrote January 400 calls. I do not annualize this dividend capture trade, as I do it quarterly and try to unwind as soon as I can for 1% profit. Haven't found a good formula for SPY, but I try to do it fairly often on a number of stocks. On less volatile stocks like KO, XOM, JNJ etc the best is just to do an ITM call before ex-div date aiming at 0.1-0.3% profit and 100% chance of getting called away without getting the dividend. Last year, I earned about 8% of my total portfolio by doing this regularly. An extra benefit, tax-wise, is that one can build up cost averages on these stocks.
