Let's go back to your original post.
Equity XYZ gapped down, and you expect that it will go up. So you bought a call and thought that as it goes up, the call premium would go up. Let me guess, you bought an out of the money call because it was so cheap, right?
Anyway, this is how you should structure the trade, by creating a synthetic covered call.
You buy a long term call deep in the money, with a delta of 80. You then sell a call in the current month near the price that you think the market is going, or slightly below. You purchase several of these option pairs, and it shows that the delta of your position is 110, and you have a nice theta of $2.50. And the total cost is less than a real covered call, using stocks.
What is going on here? As the market moves up, you benefit from the positive move, for every dollar move your position gains $1.10. If the market stays where it is at, you make $2.50 per day. And volatility effect (vega) is negligible, since you are both short and long options.
Here is an example from DHR (Danaher):
Market is now 77.78 after a major move down. You expect it to go back up to 80 in the near future, so you can structure the trade like this:
2xB Sep 65 call
2xS Jun 80 call @ 13.10
delta is about 100 (similar to straight stock position), theta is 8.50 (you make this if the position sits still), and vega is a reasonable 8.7.
The total cost is $2620, compared to 100 shares at $7778, the only major disadvantage being that you do not participate in dividends.
