A covered call is a financial market transaction in which the seller of call options owns the corresponding amount of the underlying instrumentsuch as shares of put option trading books in tamil stock or other securities. If a trader buys the underlying instrument at the same time the trader 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 the buyer decides to exercise. 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. Since in equilibrium the payoffs on the covered call position is the same as a short put position, the price or premium should be the same as the premium of the short put or naked put. Losses cannot be prevented, but merely reduced in a covered call position.

This "protection" has its potential disadvantage if the price of the stock increases.

If, before expiration, the spot price does not reach the strike price, the investor might repeat the same process again if he believes that stock will either fall or be neutral. A call option can be sold even if the option writer "A" does not initially own the underlying stock, but is buying the stock at the same time. This is called a "buy write". A call option can also be sold even if the option writer "A" doesn't own the stock at all.

This is called a "naked call". It is more dangerous, as the option writer can later be forced to buy the stock at the then-current market price, then sell it immediately to the option owner at the low strike price if the naked option is ever exercised. This strategy is sometimes marketed as being "safe" or "conservative" put option trading books in tamil even "hedging risk" as it provides premium income, but its put option trading books in tamil have been well known at least since when Fischer Black published "Fact and Fantasy in the Use of Options".
