As siumlator 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 tradong option should change when the price of the underlying stock rises by one dollar. The normalized deltas above show the actual dollar amount simultor will gain or lose. For example, if you owned the December 60 put with a delta of For related reading, see: What are the limitations of using delta to hedge options? 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.

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.

### What are vega-neutral trading strategies?

Vega is useful to option traders because implied volatility tends not to be static. Knowing the vega Veega his portfolio, the option trader knows the extent to which he is exposed to changes in implied volatility. How does vega vary from option to option? Vega is generally larger in options that have a longer time until they expire, other things being equal. Why is this?

## Vega-neutral trading strategies

This tends to increase simklator value of an option because simualtor increases its likelihood of expiring in-the-money. Now for optione that still have a long life ahead of them, this increase in volatility will be more beneficial than say for options that expire in the next 10 minutes. In other words, longer term options are more sensitive to changes in implied volatility, which is just another way of saying that they have higher vega. Adding the vega of any options is only strictly valid if the implied volatility changes affecting the options are likely to be very similar.

For example, a ratio call spread made up of two options with similar strikes, struck on the same underlying and expiring at the same time, may well be genuinely vega-neutral. If the options in the spread have a different expiration date, then adding and subtracting raw vega numbers may be a misleading thing to do.

This is because implied volatility tends NOT to move identically across the term structure of options. For example, if the 3 month implied volatility rises, 6 month implied volatility may also rise; but not necessarily by the same amount. It all depends on the degree of correlation between the implied volatilities of the options in question. One adjustment that can be made for options on the same underlying but with different expirations, is to use a time-weighted vega. This makes the assumption that the implied volatilities across time for options on a single underlying will move in a way that is related to the time each option has until expiry.

Typically, the adjustment made involves the square root of time. There is certainly a case that a time-adjusted vega-neutral position that covers multiple expirations is more meaningful than the raw vega-neutral equivalent. But the time-adjusted vega is only as good as the assumptions it is built on. Many traders will look at both the raw vega and a time-adjusted vega as well as knowing their vega per month, in order to get the complete picture.
