The article Getting To Know The Greeks discusses risk measures such as delta , gamma, theta and vega , which are summarized in figure 1 below. This article takes a closer look at delta as it relates to actual and combined positions - known as position delta - which is a very important concept for option sellers. Below is a review of the risk measure delta, and an explanation of position delta, including an example of what it means to be position-delta neutral.

Review the basics of options, from simple puts and calls, to strangles and straddles in Investopedia Academy's Options for Beginners course. Let's review some basic concepts before jumping right into position delta. Delta is one of four major risk measures used by option traders.

Delta measures the degree to which an option is exposed to shifts in the price of the underlying asset i. Values range from 1. For example, if you buy a call or a put option that is just out of the money i.

Generally speaking, an at-the-money option usually has a delta at approximately 0. Call delta values range from 0 to 1. As you can see, the at-the-money call option strike price at in figure 2 has a 0.

Keep in mind, these call delta values are all positive because we are dealing with long call options, a point to which we will return later. If these were puts, the same values would have a negative sign attached to them. This reflects the fact that put options increase in value when the underlying asset price falls. An inverse relationship is indicated by the negative delta sign.

You will see below, when we look at short option positions and the concept of position delta, that the story gets a bit more complicated. At this point, you might be wondering what these delta values are telling you.

Let's use the following example to help illustrate the concept of simple delta and the meaning of these values. A delta value of 0. We say "approximately" because as the underlying moves, delta will change as well. Be aware that as the option gets further in the money, delta approaches 1. At these extremes there is a near or actual one-for-one relationship between changes in the price of the underlying and subsequent changes in the option price.

In effect, at delta values of —1. Also keep in mind that this simple example assumes no change in other variables like the following:. As a transition into looking at position delta, let's first look at how short and long positions change the picture somewhat. First, the negative and positive signs for values of delta mentioned above do not tell the full story. As indicated in figure 3 below, if you are long a call or a put that is, you purchased them to open these positions , then the put will be delta negative and the call delta positive; however, our actual position will determine the delta of the option as it appears in our portfolio.

Note how the signs are reversed for short put and short call. The delta sign in your portfolio for this position will be positive, not negative.

This is because the value of the position will increase if the underlying increases. Likewise, if you are short a call position, you will see that the sign is reversed. The short call now acquires a negative delta, which means that if the underlying rises, the short call position will lose value. This concept leads us into position delta.

Many of the intricacies involved in trading options is minimized or eliminated when trading synthetic options. Position delta can be understood by reference to the idea of a hedge ratio. Essentially, delta is a hedge ratio because it tells us how many options contracts are needed to hedge a long or short position in the underlying. For example, if an at-the-money call option has a delta value of approximately 0.

In other words, you need two long call options to hedge one short futures contract. Two long call options x delta of 0. In this example we would say that we are position-delta neutral. By changing the ratio of calls to number of positions in the underlying, we can turn this position delta either positive or negative.

For example, if we are bullish, we might add another long call, so we are now delta positive because our overall strategy is set to gain if the futures rise.

We would have three long calls with delta of 0. On the other hand, if we are bearish, we could reduce our long calls to just one, which we would now make us net short position delta. This means that we are net short the futures by Once you're comfortable with these aforementioned concepts, you can take advantage of advanced trading strategies.

To interpret position delta values, you must first understand the concept of the simple delta risk factor and its relation to long and short positions. With these fundamentals in place, you can begin to use position delta to measure how net-long or net-short the underlying you are when taking into account your entire portfolio of options and futures. Remember, there is risk of loss in trading options and futures, so only trade with risk capital.
