I occasionally sell covered calls but I'm no expert. My rule is not to sell unless the strike price is one I would be happy to receive at that moment. With that criteria I don't find a lot of attractive options pricing. I might pickup a thousand extra a year. Usually the calls expire but I recently had one exercised. I'd sold calls on that stock several times. Left a little on the table when it was exercised but looking at all the calls that had expired on the stock I was well ahead of the game.

My view is if I can't get a strike price I want to sell at and a descent price for the call, I'm just gambling. Not worth losing a stock I like for a 10 cent call.
