Ok. Start here for the basics and terminology so I don't repeat it all here.
Options can be a powerful tool to add to your investing/trading toolkit. They can dramatically increase your risk or they can mitigate it and everything in between. This thread is for discussing options plays, options education and questions. I have been trading options for about 20 yrs now...

After reading that come back here.
No margin is involved. You are selling call options on shares you already own.
For this example I am using T.
You buy 100 T at $18.50 (today's price).
You then turn around and write (sell) a call option on those 100 shares. For this example we will pick the $19 strike expiring on Jan 20. You receive approximately 20 cents (x100).
This option is a contract that says you will sell your T shares to the call buyer at $19 per share on Jan 20th. Even if the price is above $19.
This stock goes ex-div around Jan 6 so you as the owner of the stock will get that 28 cents. So if the stock ends up at $19 or above after the 20th you will get:
$19 per share (the call option strike price).
20 cents (the call option premium)
28 cents (the stock dividend)
Total of $19.48 on a $18.50 investment. That is 5.3% return for a month or annualized to a 64% return.
If the stock doesn't end at $19 or above then they won't buy the stock and you keep the 20 premium and do it all over again. Rinse and repeat adjusting the strike price with each each rinse.
Downsides. You buy the stock and it drops a buck or two. Your initial investment is in the red but it's a paper loss and it doesn't impact you from continuing the covered calls. However, if the stock drops too much you might not be able to sell covered calls at a strike above your cost basis. You are taking on risk if you sell calls on a strike below your cost basis.
This is not a get rich quick scheme. It is probably the exact opposite. It is a slow drip of profit. The stocks we look at for this pay a solid dividend which you then supplement with call option premium. This is not the strategy employed during a hot bull market. But it is good in a sideways/down market because you are betting the stock price doesn't rise much. If it does go up and you have to sell your stock, then you are still making money. This just limits the amount you can make. If it goes to $20 and you have to sell at $19, well it will sort of suck, but you focus on what you made not what you didn't make.
This seems like small change and it is. But this is the numbers on a single contract. Most people don't use single contracts. In the example above, what if you had 10 contracts? Instead of making $98 for a month you make $980. Start small and learn the game.
There is a ton more to learn once you understand the basics (the math of the Greeks). But that is another discussion.
