A derivative\u2019s delta is defined as its price movement in relation to the change in price of its underlying asset. It can also sometimes be referred to as a hedge ratio, and is most often used when dealing in options.<\/p>

Delta is given as the amount an option\u2019s price will move when its underlying asset changes one point in price. A delta of 0.5, for instance, will see the price of an option move 0.5 for every one point move of its asset. A delta of one means that the option will mirror the price changes of \u00a0its underlying asset. A put option\u2019s delta has a value in the range 0 to -1 and a call option\u2019s in the range of 0 to 1.<\/p>

Depending on whether the derivative is a call or a put, delta can be either shown as a negative or a positive figure. This is because a put option, for example, will have a price that moves inversely to the price of its underlying asset. Delta is one of the \u2018Greeks\u2019: a set of variables of risk involved in options trading<\/p>

Formula of delta<\/strong><\/h2>

Delta (\u0394) is a measure of the sensitivity of an option\u2019s price changes relative to the changes in the underlying asset\u2019s price. In other words, if the price of the underlying asset increases by $1, the price of the option will change by \u0394 amount. Mathematically, the delta is found by:<\/p>

Examples of Delta<\/strong><\/h2>

Let’s assume there is a publicly-traded corporation called bicorn. Shares of its stock are bought and sold on a stock exchange, and there are put options and call options traded for those shares. The delta for the call option on bicorn shares is 0.35. That means that a $1 change in the price of bicorn stock generates a $0.35 change in the price of bicorn call options. Thus, if bicorn shares trade at $20 and the call option trades at $2, a change in the price of bicorn shares to $21 means the call option will increase to a price of $2.35.<\/p>

Put options work in the opposite way. If the put option on bicorn shares has a delta of -$0.65, then a $1 increase in bicorn share price generates a $.65 decrease in the price of bicorn put options. So if bicorn shares trade at $20 and the put option trades at $2, then bicorn shares increase to $21, and the put option will decrease to a price of $1.35.<\/p>
