Greek trading strategies
Option Greeks. Option Greeks are a way of understanding the individual elements that help determine option pricing. Each greek represents a different "sensitivity" of the option. Understanding them is important for two reasons: assessing option pricing and option risk management. In options trading, you may notice the use of certain greek alphabets when describing risks associated with various positions. They are known as "the greeks" and here, in this article, we shall discuss the four most commonly used ones. They are delta, gamma, theta and vega. Note how delta and gamma change as the stock price moves up or down from $50 and the option moves in- or out-of-the-money. As you can see, the price of at-the-money options will change more significantly than the price of in- or out-of-the-money options with the same expiration.
