In Meet the Greeks we discussed how delta affects the value of individual options.

Think of position delta this way: A single call contract with a delta of. But generally speaking, an option contract will represent shares of stock. So you need to multiply the delta by shares: Owning a single call contract with a delta of. It works the same way with puts, but keep in mind that puts have a negative delta. So if you own a put contract with a delta of -. Say you own 10 contracts of XYZ calls, each with a delta of. To calculate position delta, multiply. This gives you a result of That means your call options are acting as a substitute for shares of the underlying stock.

Much of the time your option strategies will be more complex than a few call options with the same strike price. You might use multi-leg strategies, and you might even run different strategies on the same underlying stock at the same time. Each of those strategies might involve options with different strike prices and expiration dates.

For example, you might wind up running an iron condor and a long calendar spread with calls simultaneously on the same underlying stock. The deltas of some individual options in the complete option position will be positive and some will be negative. For instance, consider a long call spread with two legs. Example 2 shows the details of an XYZ long call spread with a long strike and a short strike, both with the same expiration date.

The delta of the strike call is. So to determine the total delta, we multiply. Now you simply add the deltas from each leg together to determine your position delta: Therefore, the total value of this position will behave like shares of stock XYZ.

Your net position delta for options on any underlying stock represents your current risk relative to a change in the stock price. If not, you may want to attend to that risk. You can do so by closing out part of your position or by adding negative deltas, perhaps by buying puts or selling stock short. The same logic applies if you hold a position with a high negative delta. You will have the same risk as a short position in the stock.

To adjust your risk, you could dump part of your position, buy calls, or buy the stock. Just as gamma will affect the delta of one option as the stock price changes, it will affect the net delta of your entire position as well.

The number of shares for which your options act as a substitute will change every time the stock price changes. If you have a TradeKing account, keeping an eye on position delta is easy.
