Corporate Actions Can Affect Your Options?

Options are financial derivatives that derive their value from an underlying asset, such as stocks.

    📈 Dividends and Their Impact on Option Pricing

    When a company pays out dividends, it directly affects the stock price, which in turn influences the option’s value. For call options, dividend payments can lead to a decrease in value, while put options might see an increase.


    XYZ Corp announces a $1 dividend. The stock price typically drops by approximately the dividend amount on the ex-dividend date. If you own a call option, the underlying stock's price drop can decrease the option's value.

    🔀 Stock Splits and Option Adjustments

    A stock split increases the number of shares while reducing the price per share without affecting the company’s overall market capitalization. Options are adjusted to reflect these changes to maintain the position’s overall value.


    Imagine you own a call option contract for ABC Inc. with a strike price of $100. If ABC Inc. undergoes a 2-for-1 stock split, your option will now cover 200 shares at a strike price of $50.

    🏢 Other Corporate Actions and Their Effects

    Mergers, acquisitions, and spin-offs are other corporate actions that can significantly impact option pricing. The terms of these events are usually unique, and the resulting option adjustments can vary.


    If DEF Company is acquired by another company, the terms of the acquisition will determine how existing options on DEF are handled. They could be adjusted to reflect the terms of the deal or even become options on the acquiring company's stock.

    🧮 Calculating the New Value of Options Post-Corporate Action

    To calculate the new value of options after a corporate action, you need to understand the specific terms of the action and how they affect the contract’s terms, including the number of shares, the strike price, and the option’s premium.


    Before a 2-for-1 stock split:
    - 1 call option contract with a strike price of $100
    - Option premium is $5
    After the stock split:
    - 1 call option contract now covers 200 shares with a strike price of $50
    - The new option premium will be adjusted, potentially to around $2.50, reflecting the new strike price.

    📚 Real Stories: The Tale of Apple’s 7-for-1 Stock Split

    In 2014, Apple Inc. announced a 7-for-1 stock split. This event was a significant one for options holders. The split caused the strike price of each option to be divided by seven, and the number of contracts was multiplied by seven. This meant that if an investor held an option contract with a strike price of $700, after the split, they would hold 7 contracts with a strike price of $100 each.
