Understanding Option Greeks

The Bottom Line Trying to predict what will happen to the price of a single option or a position involving multiple options as the market changes can be a difficult undertaking. Options traders often refer to the delta, gamma, vega, and theta of their option positions.

These terms may seem confusing and intimidating to exchange for trading binary options option traders, but broken down, the Greeks refer to simple concepts that can help you better understand the risk and potential reward of an option position.

For instance, the delta measures the sensitivity of an option's premium to a change in the price of the underlying asset; while theta tells you how its price will change as time passes.

Together, the Greeks let you understand the risk exposures related to an option, or book of options. That means the values are projected based on mathematical models.

The Greeks need to be calculated, and their accuracy is only as good as the model used to compute them. To get them, you will need access to a computerized solution that calculates them for you. Most of the retail brokerages interactive brokers also provide this information.

(At least the four most important ones)

Naturally, you could learn the math and calculate the Greeks by hand for each option, but, given the large number of options available and time constraints, that would be unrealistic. It is formatted to show the mid- market pricedelta, gamma, theta, and vega for each option.

As we options options greeks what each of the Greeks mean, you can refer to knockout options illustration to help you understand the concepts. As you move from top to bottom, the expiration dates increase from March to April and then to May.

The actual number of days left until expiration is shown in parentheses in the description column in the center of the matrix. This is the format we used in our Options for Beginners class at Investopedia Academy. The delta, gamma, theta, and vega figures shown above options options greeks normalized for dollars.

To normalize the Greeks for dollars, you simply multiply them by the contract multiplier of the option.

The contract multiplier would be shares for most stock options. How paid options strategies various Greeks move as conditions change depends on how far the strike price is from the actual price of the stock, and how much time is left until expiration.

As the Underlying Stock Price Changes—Delta and Gamma Delta measures the sensitivity of an option's theoretical value to a change in the price of the underlying asset. It is normally represented as a number between minus one and one, and it indicates how much the value of an options options greeks should change when the price of the underlying stock rises by one dollar.

The normalized deltas above show the actual dollar amount you will gain or lose. For example, if you owned the December 60 put with a delta of Call options have positive deltas and put options have negative deltas. At-the-money options generally have deltas around Deep-in-the-money options might have a delta of 80 or higher, while out-of-the-money options have deltas as small as 20 or less.

Meet the Greeks At least the four most important ones NOTE: The Greeks represent the consensus of the marketplace as to how the option will react to changes in certain variables associated with the pricing of an option contract. There is no guarantee that these forecasts will be correct. And as Plato would certainly tell you, in the real world things tend not to work quite as perfectly as in an ideal one.

As the stock price moves, delta will change as the option becomes further in- or out-of-the-money. Meanwhile, far-out-of-the-money options won't move much in absolute dollar terms. Delta is also a very important number to consider when constructing combination positions.

Since delta is such an important factor, options traders are also interested in how delta may change as the stock price moves. Gamma measures the rate of change in the delta for each one-point increase in the underlying asset. It is a valuable tool in helping you forecast changes in the delta of an option or an overall position. Unlike delta, gamma is always positive for both calls and puts. Options options greeks in Volatility and the Passage of Time—Theta and Vega Theta is a measure of the time decay of an option, the dollar amount an option will lose each day due to the passage of time.

Futures contracts can be an effective and efficient risk management or trading tool.

For at-the-money options, theta increases as an option approaches the expiration date. For in- and out-of-the-money options, theta decreases as an option approaches expiration. The further out in time you go, the smaller the time decay will be for an option.

If you want to own an option, it is advantageous to purchase longer-term contracts. If you want a strategy that profits from time decay, you will want to short the shorter-term options, so the loss in value due to time happens quickly.
