It is not really a loss. If you do the strategy correctly, then you still made a gain overall.
Unless the stock completely runs away and never pulls back (in which case you just bite the bullet and close out the short call), sooner or later the short call expires worthless. And hopefully you moved it up in strike too as you roll out...
Yeah, I tried this strategy once a while ago and it didn't go well that one time but I didn't stick with it. I started again last week and am happy with my results so far.
