Could you give the breakdown for the trade? Are you saying that you traded ref stock at 39.8?
I bought 1K stocks and ten 39.5 puts and the same time sold ten 39.5 calls for $39,842 yesterday, when the stock was at 39.9... (Ameritrade calls this a collar with stock)
Overnight we got $490 in dividend (for 1K stocks) and the stock opened down with a dividend gap. The calls were pretty much worthless, a few cents, the puts protected and locked in my stock price to 39.5...
Today I closed the position a little hastily for 39400. Thus the loss was $442, but in 2 weeks I will get $490 in dividends, thus eventually profiting about $50. Had I waited 10 minutes more for a better fill when the options settled after the open, I could have made 3-4 cents more, profiting $80-90 on the whole deal, without much risk...
Yesterday there were 4 candidates for this kind of trade: T, VZ, GIS and APD
Pretty much getting the fill when setting this up tells you how it will work out.(projected profits) If next day the price stays above the strike, you just let the stocks go because of the short calls, and save some on commission.
There is actually a book written about this, although the author cheated because, well read the reviews. Nevertheless I didn't cheat and it did work with real money...

The real question is, just how often can this be repeated in a year?
