Option Greek In The Market

By Walter Fox

Trading is an old age practice of exchanging goods between two or more individuals or groups in the interest of all the parties involved in the transaction. After the invention of currency it has become a main media of exchange and every countryas power is measured in term of its currency power. Subsequently new concepts of trade originated in the form of stock trading and forex trading.

All forms of trade have risk that are connected to them and the stock trading and forex trading is no exception, infact the risk is higher. However options trading are the most preferred of them all. This is mainly because of its liquid nature and the high revenues. Share markets are rapidly and impressively growing plus there is a growing competition among the traders some of whom are well prepared with information from the internet making the share markets more challenging but at the same time chances of making money has also rocketed.

All these progress and advancement in the options trading systems, has forced traders to let the stock option plans and policies face the new tests of the stock market. Although option trading systems may seem easy like the other systems, many people have lost their investments due to lack of adequate know-how about this form of trade.

So the hunt for suitable weapons to protect the traders started thus new concepts like brokers ticks, trading techniques, advisors in the form of software are appeared in the market. Even this software is capable of trading on behalf of the trader and this system is proved to be successful.

In relation to the same, another model referred to as the Options Greek came up and became saturated within the trading community mostly to those who were dealing with large sums of money within the stock market and other trading areas.

The Black-Scholes model has some numerical features; these features are named after the Greek letters used to symbolize them in equations. As long as you are willing to spend and trade in an adequate amount of money in the five options Greek, then you can be one of the most thriving traders in this business.

The five option Greek are very close to the heart of fund managers because of its pin point accuracy in calculating the changes in the value of their portfolio. The five option Greek are
Delta- a measure of an optionas sensitivity to changes in the price of the underlying asset
Gamma - a measure of deltaas sensitivity to changes in the price of the underlying asset
Vega - a measure of an optionas sensitivity to changes in the volatility of the underlying asset
Theta - a measure of an optionas sensitivity to time decay
Rho - a measure of an optionas sensitivity to changes in the risk free interest rate

The main advantage of Option Greeks is it allows the trader to precisely determine the changes which takes place in the value of contracts in his portfolio with the changes in the different factors that affects the total value of the stock options. The ability of this system to mathematically estimate these value changes gives the trader an option to change his strategy. For a new comer in the market with little experience of the shocks in the market, option Greeks is the best friend which can guide him on every stage of trading.
