I fully agree that it would be stupid of me to write calls against my core position, but that's not the point. The strategy is to set up a separate option portfolio in order to take advantage of IV's that are currently in the 90's(!). It's because I have a bullish view of MNTA's prospects that I'd consider the strategy - getting called would be a favorable outcome - 10% on investment for just over a month's work, plus the gain on the core holdings. Can't beat that with a stick.
