According to Wikipedia a covered call is a financial market transaction in which the seller of call options owns the corresponding amount of the underlying instrument, such as shares of a stock or other securities. If the trader buys the underlying instrument at the same time as he sells the call, the strategy is often called a "buy-write" strategy. In equilibrium, the strategy has the same payoffs as writing a put option.
The long position in the underlying instrument is said to provide the "cover" as the shares can be delivered to the buyer of the call if he decides to exercise.
Writing a call generates income in the form of the premium paid by the option buyer. And if the stock price remains stable or increases, then the writer will be able to keep this income as a profit, even though the profit may have been higher if no call were written. The risk of stock ownership is not eliminated. If the stock price declines, then the net position will likely lose money.
If you did not understand, perhaps this analogy helps:
Imagine that you are the season ticket holder of 4 good seats for a major league football team at the beginning of the season. A lot of people think the team is headed for the Superbowl, but you are pessimistic. You’d like to cash in on the current hype and get some money now for the last home game of the season. On craigslist you offer to sell the rights to this game. Your offer doesn’t force the buyer to buy the tickets, but gives the buyer the right to buy the tickets from you at face value any time before the game.
If your team is undefeated 4 games into the season the value of your offer will go up. If the last game of the season determines whether the team goes to the playoffs or not your offer could become quite valuable–essentially the difference between what the scalpers are charging for comparable tickets and the face price of the tickets.
On the other hand, if your team is near elimination from the playoffs halfway through the season your offer will be almost worthless—who would pay money for the right to buy tickets at face value that will probably be cheap on the street? If the last game of the season ends up being a meaningless contest between two loser teams you will probably have to sell your tickets at a discount if you don’t want to go yourself.
Your offer on Craig’s list has similar characteristics to selling stock options on stock you own—a covered call. You give up the upside on an asset you own in exchange for money upfront. No laws of nature have been broken—relax…
Scientists at NASA’s Jet Propulsion Laboratory have used computer models to predict that the cataclysmic Chilean earthquake may have shifted the Earth’s axis by three inches, which will ultimately result in shorter days.
Days are estimated to have been shortened by 1.26 microseconds, and more visible changes include islands changing their position. One of them, Santa María, may have risen two meters as a result of the quake. “It’s what we call the ice-skater effect,” David Kerridge, head of Earth hazards and systems at the British Geological Survey in Edinburgh, provided an analogy, “As the ice skater puts when she’s going around in a circle, and she pulls her arms in, she gets faster and faster. It’s the same idea with the Earth going around if you change the distribution of mass, the rotation rate changes.”
