Hedge ratio call options

By Simon Gleadall , CEO of Volcube. If we have an understanding of how volatile the underlying product price is, then we have a handle on how exposed our option position is to these price changes.

This gives us a useful indication of the basic price exposure we face.

Hedge ratio (delta) Definition - ysygohajavin.web.fc2.com

Knowing how much the option value will change when the underlying product price changes, allows us to hedge appropriately. This is easiest to see by working through a simple example. The delta tells us how much cheese to buy as a hedge. It should be obvious. The delta tells us exactly how to hedge options to prevent losses due to changes in the price of the underlying.

This one probably gets more weight than it should, but can be useful nevertheless. Basically, delta can under certain assumptions be seen as the probability or likelihood that an option will expire in-the-money.

This is used by some traders in order to select which options to trade. Using the delta, the trader can find out which put i.

This probability is highly theoretical. It is not a FACT about the options that will always be true.

All it means is that if every assumption in the pricing model that has been used to formulate the delta turns out to be true, then the delta can be interpreted as the probability of expiring in-the-money, in some cases. This is very unlikely to be the case consistently or even frequently.

Volatility can be higher or lower than expected. Interest rates can move. Indeed, for some options where cost of carry or dividends are relevant, this interpretation of delta is even more precarious. Nevertheless, as a rule of thumb, option delta as the probability of expiring in-the-money is undoubtedly useful to know. Probably the main use of delta in the markets.

We could neutralise this risk by selling 20 lots of cheese the exact same idea as delta viewed as the hedge ratio or we could trade options to achieve the same effect. Our equivalent position in the underlying product becomes zero. When traders refer to being long or short deltas they mean long or short an equivalent amount of the underlying, whether this is coming from an option position or a straight position in the underlying.

All these interpretations come from the same definition of option delta. Indeed, they are identities ; exactly the same thing but viewed from a different perspective.
