i tell u about option
What is an Option?
An option is a contract to buy or sell a specific product known as the option . For equity options, the underlying instrument is a stock, exchange-traded fund product. The contract itself is very precise. It establishes a specific price, called the strike price, at which the contract may be exercised, or acted on. And it has an expiration date. When an option expires, it no longer has value and no longer exists.
Options come in two types, calls and puts, and you can buy or sell either type.
Buying and SellingIf you buy a call, you have the right to buy the underlying instrument at the strike price on or before the expiration date. If you buy a put, you have the right to sell the underlying instrument on or before expiration. In either case, as the option holder, you also have the right to sell the option to another buyer during its term or to let it expire worthless.
The situation is different if you write, or "sell to open", an option. Selling to open a short option position obligates you, the writer, to fulfill your side of the contract if the holder wishes to exercise. When you sell a call as an opening transaction, you're obligated to sell the underlying interest at the strike price, if you're assigned. When you sell a put as an opening transaction, you're obligated to buy the underlying interest, if assigned. As a writer, you have no control over whether or not a contract is exercised, and you need to recognize that exercise is always possible at any time until the expiration date. But just as the buyer can sell an option back into the market rather than exercising it, as a writer you can purchase an offsetting contract, provided you have not been assigned, and end your obligation to meet the terms of the contract. When offsetting a short option position, you would enter a "buy to close" transaction.
As Premium
When you buy an option, the purchase price is called the premium. If you sell, the premium is the amount you receive. The premium isn't fixed and changes constantly - so the premium you pay today is likely to be higher or lower than the premium yesterday or tomorrow. What those changing prices reflect is the give and take between what buyers are willing to pay and what sellers are willing to accept for the option. The point at which there's agreement becomes the price for that transaction, and then the process begins again.
If you buy options, you start out with what's known as a net debit. That means you've spent money you might never recover if you don't sell your option at a profit or exercise it. And if you do make money on a transaction, you must subtract the cost of the premium from any income you realize to find your net profit.
As a seller, on the other hand, you begin with a net credit because you collect the premium. If the option is never exercised, you keep the money. If the option is exercised, you still get to keep the premium, but are obligated to buy or sell the underlying stock if you're assigned.
The Value of OptionsWhat a particular options contract is worth to a buyer or seller is measured by how likely it is to meet their expectations. In the language of options, that's determined by whether or not the option is, or is likely to be, in-the-money or out-of-the-money at expiration. A call option is in-the-money if the current market value of the underlying stock is above the exercise price of the option, and out-of-the-money if the stock is below the exercise price. A put option is in-the-money if the current market value of the underlying stock is below the exercise price and out-of-the-money if it is above it. If an option is not in-the-money at expiration, the option is assumed to be worthless.
An option's premium has two parts: an intrinsic value and a time value. Intrinsic value is the amount by which the option is in-the-money. Time value is the difference between whatever the intrinsic value is and what the premium is. The longer the amount of time for market conditions to work to your benefit, the greater the time value.
Options Prices Several factors, including supply and demand in the market where the option is traded, affect the price of an option, as is the case with an individual stock. What's happening in the overall investment markets and the economy at large are two of the broad influences. The identity of the underlying instrument, how it traditionally behaves, and what it is doing at the moment are more specific ones. Its volatility is also an important factor, as investors attempt to gauge how likely it is that an option will move in-the-money.
