# What Is Delta In Options Trading?

Understanding the Delta of an option is crucial for both new and seasoned traders. It’s one of five specific calculations called “Greeks,” which help measure specific factors that could influence the price of an options contract.

Delta is a metric that helps you gauge how much the value of an option contract is expected to change, as it coincides with the relative price movements of its underlying stock. It’s an extremely useful measuring tool for options traders, who can use it to establish thresholds for entering and exiting trades, set potential profit targets, and limit their risk exposure.

In this article, we’ll elaborate more on the definition and specific functions of Delta. We’ll examine some specific scenarios for using it, and provide examples to help options traders of all experience levels effectively utilize this key metric.

### What is Option Delta?

To reiterate – Delta is one of the key ‘Greeks’ in options trading. It represents the rate of change between an option contract’s price and a \$1 change in the underlying asset’s price. Delta breaks down into two main categories – Positive and Negative. They’re measured on a spectrum that ranges from -100 to +100.

### Positive Delta (Call Options)

Positive Delta correlates with options calls, indicating their price is expected to rise as the underlying stock price increases.

For example, let’s say a call option’s Delta is +15. That means every time its underlying stock price rises by \$1, each contract in this specific option call is expected to increase by \$.15.

However, since one option contains 100 contracts, the cumulative price of each option call in this scenario is projected to increase by \$15.

### Negative Delta (Put Options)

Negative Delta pertains to options puts, meaning their price increases as the underlying asset’s price decreases.

In this example, we’ll use a Negative Delta of -10. Whenever the underlying stock price decreases by \$1, each contract for this option put is expected to increase by \$.10.

That means the cumulative price of all 100 contracts for one option put in this scenario is projected to increase by \$10.

### Options Delta Scenario Analysis

Understanding and applying Delta can significantly affect your trading strategy. Let’s explore two scenarios for respectively utilizing the Positive and Negative Deltas.

#### Selling a Call (Negative)

Selling a call option involves entering into a contract where you agree to sell the underlying stock at a specified price (the strike price) – if the buyer of that option exercises their right to buy those shares. As the seller of a call option, you receive a premium payment upfront from the buyer.

In this scenario, you can use Delta to assess how likely an option may be exercised. A higher Delta indicates a higher probability that the option will be exercised. This means there’s a greater chance the stock price will exceed the strike price. Conversely, a lower Delta suggests a lower likelihood that the option will be exercised. This means there’s a greater chance the underlying stock may not reach the strike price by expiration.

Analyzing the Delta of a call option you’re selling can help you gauge the potential risk and reward of that trade. A higher Delta implies greater risk if the stock price rises significantly. If this happens, you may be required to sell the stock at a lower price than its market value. A lower Delta indicates lower risk, however, this could also mean it results in lower potential profit if the stock price does not increase substantially.

#### Selling a Put (Positive)

Selling a put option in options trading involves entering into a contract where the seller (aka the writer) agrees to buy the underlying asset at a predetermined price (the strike price) if the buyer chooses to exercise the option before – or at – the expiration date. In exchange for this obligation, the seller receives a premium payment upfront from the buyer. By selling a put option, the seller is essentially betting that the underlying stock price will either remain stable or increase in value, allowing them to keep the premium without having to buy the asset. If the underlying stock price falls below the strike price, the seller may be obligated to purchase the stock at the strike price, potentially resulting in a loss.

When selling a put option, Delta can help you assess the option’s profit potential. A higher Negative Delta indicates a higher probability that the option will expire in the money. That means there’s a greater chance the stock price will fall below the strike price by expiration. Conversely, a lower Negative Delta suggests a lower likelihood of profitability, indicating that the stock price may not decline sufficiently to make the option profitable.

A higher Negative Delta implies greater potential profit if the stock price declines significantly, as the option’s value would increase more rapidly. Conversely, a lower Negative Delta indicates lower potential profit, but also lower risk if the stock price does not decrease substantially.

### Portfolio Delta

In addition to helping you set expectations for an individual option’s price movement, Delta can be very useful when balancing your stock portfolio. This metric can provide valuable insight into the overall sensitivity of your portfolio, relative to market movement.

Let’s look at a few properties Delta can help determine in your portfolio:

#### Sensitivity

By summing up the Deltas of all options positions in your portfolio, you can estimate its overall sensitivity to changes in their underlying asset prices. A Positive Delta indicates that your portfolio is bullish. That means it will benefit from rising prices. A Negative Delta indicates more bearish sentiment, meaning your portfolio would benefit from falling prices.

#### Risk Management

If your portfolio has a Positive Delta and you want to hedge against potential downside risk, you might look into purchasing put options or establish bearish positions to increase its Negative Delta. However, if your portfolio has a Negative Delta and you want to hedge against potential upside risk, you might want to consider buying call options or establish bullish positions to increase the Positive Delta.

#### Asset Allocation & Diversification

Based on your market outlook and risk tolerance, you can adjust the quality and quantity of your positions by adding or reducing holdings with different Delta values. A well-diversified portfolio may have positions with varying Delta values to balance exposure in different market conditions and mitigate overall risk. For example, if you anticipate a market downturn, you may increase your portfolio’s Negative Delta exposure by adding more bearish positions or purchasing put options, and vice versa.

### Conclusion

Understanding the Delta of an option is fundamental for traders at all levels. It provides valuable insights into price movements, and can be instrumental in utilizing effective risk management strategies.

Using Delta helps traders gauge the sensitivity of their portfolio and individual options to market movements. Moreover, it’s a great metric to help adjust asset allocation and diversify positions for optimizing risk-adjusted returns. Whether assessing Positive Delta for bullish positions or Negative Delta for bearish strategies, effectively leveraging this particular metric can potentially enhance your portfolio’s performance and ensure a balanced approach to trading.
