For example, option market makers use theoretical pricing models to determine probabilities given certain inputs, such as days to expiration, price of the underlying, interest rates, and volatility measures, to determine a theoretical value of an option. A market maker who can buy below and sell above theoretical value can, over time, come out ahead. Think of a farmer who has a lot of corn to sell.

And in the process of making markets and taking the other side of order flow, they accumulate inventory.

A financial option is a contract between two counterparties with the terms of the option specified in a term sheet. Option contracts may be quite complicated; however, at minimum, they usually contain the following specifications: [8]. Exchange-traded options also called "listed options" are a class of exchange-traded derivatives.

Exchange-traded options have standardized contracts, and are settled through a clearing house with fulfillment guaranteed by the Options Clearing Corporation OCC. Since the contracts are standardized, accurate pricing models are often available. Exchange-traded options include: [9] [10]. Over-the-counter options OTC options, also called "dealer options" are traded between two private parties, and are not listed on an exchange.

By avoiding an exchange, users of OTC options can narrowly tailor the terms of the option contract to suit individual business requirements.

However, OTC counterparties must establish credit lines with each other, and conform to each other's clearing and settlement procedures.

If they are combined with other positions, they can also be used in hedging. An option contract in US markets usually represents shares of the underlying security. A trader who expects a stock's price to increase can buy a call option to purchase the stock at a fixed price " strike price " at a later date, rather than purchase the stock outright.

The cash outlay on the option is the premium. The trader would have no obligation to buy the stock, but only has the right to do so at or before the expiration date. The risk of loss would be limited to the premium paid, unlike the possible loss had the stock been bought outright. The holder of an American-style call option can sell the option holding at any time until the expiration date, and would consider doing so when the stock's spot price is above the exercise price, especially if the holder expects the price of the option to drop.

By selling the option early in that situation, the trader can realise an immediate profit. Alternatively, the trader can exercise the option — for example, if there is no secondary market for the options — and then sell the stock, realising a profit.

A trader would make a profit if the spot price of the shares rises by more than the premium. For example, if the exercise price is and premium paid is 10, then if the spot price of rises to only the transaction is break-even; an increase in stock price above produces a profit. If the stock price at expiration is lower than the exercise price, the holder of the options at that time will let the call contract expire and only lose the premium or the price paid on transfer.

A trader who expects a stock's price to decrease can buy a put option to sell the stock at a fixed price "strike price" at a later date. The trader is under no obligation to sell the stock, but has the right to do so at or before the expiration date. If the stock price at expiration is below the exercise price by more than the premium paid, the trader makes a profit.

If the stock price at expiration is above the exercise price, the trader lets the put contract expire, and only loses the premium paid. In the transaction, the premium also plays a role as it enhances the break-even point. For example, if the exercise price is , the premium paid is 10, then a spot price of to 90 is not profitable. The trader makes a profit only if the spot price is below The trader exercising a put option on a stock, does not need to own the underlying asset, because most stocks can be shorted. A trader who expects a stock's price to decrease can sell the stock short or instead sell, or "write", a call.

The trader selling a call has an obligation to sell the stock to the call buyer at a fixed price "strike price". If the seller does not own the stock when the option is exercised, they are obligated to purchase the stock in the market at the prevailing market price. If the stock price decreases, the seller of the call call writer makes a profit in the amount of the premium.

If the stock price increases over the strike price by more than the amount of the premium, the seller loses money, with the potential loss being unlimited.
