While it is true that options can be bought on an individual basis, in reality options are not independent investments. The values of option are actually based on and derived from other variables; the most essential has to do with the movement of the underlying security. Therefore, options are known as derivative products. If you are interested in buying an option and looking at it price, is there a question as to how the price was thought up or calculated? Not knowing this might mean you are paying too much when you purchased it or that you are selling too cheap of a price. There is a procedure that is utilized to calculate the premium of an option and if you are intending on turning into an astute trader, it will be necessary to become familiar with how the process is done. The price of an option does not just show and pop up from nowhere. The market makers on the options exchange use very accurate software in order to place a price on each and every option depending on the conditions that are occurring until that moment. The premium or price of an option depends on a number of different variables, such as: the actual price of the underlying security, the strike price of the option, how many days remain to the expiration of the option, Volatility, the interest rates, and the dividends. These numbers are then placed into an option pricing calculator. Almost all of the pricing calculators and software utilize a formula just like the common Black Scholes option pricing model. The software then brings about a result that lets you know what the option should in theory cost. Obviously the result that is obtained from an option calculator could turn out to be very different from what the option is trading for the exchange. If it very simple to find and input the numbers into an option calculator in order to find the results of the price of options. There is one exception though and that has to do with volatility. This is because it is the one and only input that is never agreed upon by all of the people that participate in the market or positioned by the exchanges. If you are using an option calculator, you will find that it is easy to find all the other input numbers. It is always viable to obtain an actual quote for the stock or commodity, the exchanges set the strike prices and days to expiration, and the interest rates as well as the dividends are very scattered. The first items are the ones that are the most important when pricing options is concerned. Dividends and the interest rates do not play as big of a role therefore it is not necessary to worry too much about them. There are a couple other words that are commonly utilized and that have to do with the option pricing inputs, these are intrinsic value and extrinsic values.
