option delta in option trading strategies

There are striking similarities between a Bollywood film and an options trade. Just like a Bollywood film’s success relies on various factors working in harmony, an options trade’s success depends on a set of forces known as “The Option Greeks.” These Option Greeks have a real-time impact on option contracts, causing premiums to fluctuate minute by minute. It’s important to note that these forces not only influence premiums directly but also interact with one another.

To illustrate this, let’s consider two Bollywood actors, Ranbir Kapoor and Ranveer Singh. Just as these actors are independent forces in the film industry, the Option Greeks act as independent forces in the options market. Each actor can individually impact the outcome of a film (analogous to the options premium). However, if these actors were to collaborate in a single film, they would simultaneously strive to elevate themselves whilst potentially undermining each other’s performance, all with the goal of making the film a success. This analogy highlights the complexity and interplay of forces at play in options trading.

Options premiums, the Option Greeks, and the natural supply and demand dynamics of the market all influence each other. Whilst these factors operate independently, they are interconnected. The culmination of these factors is reflected in the options premium. For an options trader, understanding and assessing the variations in premiums is crucial. Developing a sense of how these factors interact is essential before entering into an options trade.

Let me introduce the Greeks to you:

Delta: Quantifies the rate at which the options premium changes in response to the underlying asset’s directional movement

Gamma: Represents the rate of change of delta itself, reflecting how the delta of an option changes as the underlying asset’s price moves

Vega: Measures the rate at which the options premium changes due to fluctuations in volatility

Theta: Evaluates the impact on the options premium caused by the remaining time until expiration

We’ll discuss these Greeks later. Today, let’s focus on comprehending the Delta.

Delta of an Option

These photos show the 24,800 CE option of Nifty. The first one was taken when the spot rate was at 24,875 and the time was 9:18 AM.

A little whilst later…

Observe the shift in premium: when Nifty was at 24,875 at 09:18 AM, the call option traded at 198. However, when it climbed to 24,920 by 10:00 AM, the same call option had risen to 210.

At 10:55 AM, Nifty dropped to 24,860, causing the option premium to decrease to 185.

It is evident that the call option premium fluctuates in line with the spot value; as the spot value increases, so does the premium, and conversely it decreases accordingly.

Take this into account—you anticipated Nifty hitting 25,100 by 3:00 PM. We comprehend that the premium will vary—but how much? What would be the worth of 24,800 CE premium if the prediction comes true?

The ‘Delta of an Option’ makes it easier to figure out how the option premium is affected by fluctuations in the underlying. To put it more simply, you can use Delta to answer questions like, “What will the option price be after a 1 point movement of the underlying?”

Hence, Delta, an Option Greek, manages to reflect the influence of the market’s directional change on the Option’s premium.

The delta is a variable quantity that can fluctuate:

Traders often find the 0 to 100 scale preferable when dealing with call options. This scale makes it easier to determine delta values; for example, a delta value of 0.55 on the 0 to 1 scale is equivalent to 55 on the 0 to 100 scale

The delta value of -0.4 can be expressed on the range from -1 to 0 as well as on the scale of -100 to 0, which would equate to -40

We will soon understand why the put option’s delta has a negative value associated with it

At this stage, I’m providing you an orientation of how this chapter will progress. Please keep this in mind, as it will help you to understand the connections between different points better.

So let’s hit the road!

For those exploring equity investment opportunities through a stock broker or consulting with a financial advisor, understanding Option Greeks proves essential when navigating the stock market. Whether evaluating trading calls or utilising a stock screener to identify opportunities, comprehending Delta enables more accurate premium predictions and sophisticated options trading strategies.
