The third Greek, Theta has different formulas for both call and put options. These are given below: In the first table on the LHS, there are 30 days remaining for the option contract to expire.

### The Greeks: Delta, Gamma, Theta, Vega, and Rho

We have a negative theta value of He has to be sure about his analysis in order to profit from trade as time decay will affect this position. This impact of time decay is evident in the table on the RHS where the time left to expiry is now 21 days with other factors remaining the same.

As a result, the value of the call option has fallen from If an options trader wants to profit from the time decay property, he can sell options instead of going long which will result in a positive theta. However, it is very essential to understand the combined behavior of Greeks on an options position to truly profit from your options position.

## Meet the Greeks

Advanced Concepts Options pricing is a highly mathematical and complex area of study. In the videos below, you can get a glimpse of the discussion held at a seminar at Narsee Monjee Institute of Management Studies between final year students of MBA graduates majoring in Finance and our Options faculty member, Mr. Watch the video to understand why!

Write in the comments section below if you have any further doubts! Vega increases or decreases with respect to the time to expiry? That means if the stock price goes up and no other pricing variables change, the price for the call will go up. If a call has a delta of.

Puts have a negative delta, between 0 and That means if the stock goes up and no other pricing variables change, the price of the option will go down. For example, if a put has a delta of.

As a general rule, in-the-money options will move more than out-of-the-money optionsand short-term options will react more than longer-term options to the same price change in the stock. As expiration nears, the delta for in-the-money calls will approach 1, reflecting a one-to-one reaction to price changes in the stock.

As expiration approaches, the delta for in-the-money puts will approach -1 and delta for out-of-the-money puts will approach 0. Technically, this is not a valid definition because the actual math behind delta is not an advanced probability calculation. However, delta is frequently used synonymously with probability in the options world. How stock price movement affects delta As an option gets further in-the-money, the probability it will be in-the-money at expiration increases as well.

As an option gets further out-of-the-money, the probability it will be in-the-money at expiration decreases. There is now a higher probability that the option will end up in-the-money at expiration. So what will happen to delta? So delta has increased from.

So delta in this case would have gone down to. This decrease in delta reflects the lower probability the option will end up in-the-money at expiration. How delta changes as expiration approaches Like stock price, time until expiration will affect the probability that options will finish in- or out-of-the-money. Gamma is the driving force behind changes in an options delta. Likewise, an option with a gamma of Most professional traders do not want to be short gamma during the last week of an options life.

Gamma is at its highest with at-the-money options. Net sellers of options will be short gamma and net buyers of options will be long gamma.

This makes sense because most sellers of options do not want the stock to move far, while buyers of options benefit from large movements. A larger gamma positive or negative leads to a larger change in delta when your stock moves.

### The Greeks in Options: Delta, Gamma, Theta and Vega

In the picture below you can see that a 10 lot at-the-money call position has a positive delta of and a gamma of positive The call position has a delta of 86 and a gamma of The gamma for the at-the-money position is significantly higher.

On the right side of the picture is a custom scenario. The delta for the calls has risen by to whereas the calls have only risen by Here you can see that the Dec calls have a delta of and a gamma of The June, calls have a similar delta atbut a much lower gamma at The above analysis confirms that at-the-money options have higher gamma risk than out-of-the-money options and shorter dated options have higher gamma risk than longer dated options. When implied volatility on a stock is low, the gamma of at-the-money options will be high, while the gamma of deep out-of-the-money options will be near zero.
