What's wrong with this simple plan. I'm new at this so be gentle.
Buy stock XYZ for $20 and write a call option with a strike of say $22 (a 10% move will get you exercised). Then, set your stop loss at the current price minus the premium you recieved. So, if the stock drops past BE you exit the whole position without a loss, but if it goes up then you win. It's a "can't lose" trade!
Of course, if the stock opens with a huge gap then you get your arze handed to you. And then there are brokerage fees as well.
What else am I missing? This is a kind of "dorathy dixer" question to elicit some responses, don't panic I'm not going to do this just yet. Cheers. Humor me.
