Understanding How Dividends Affect Option Prices

Dividend payments for a company have an influence on how options for that stock are valued. On the ex-dividend date (the first trading day when an impending dividend payment is not reflected in a stock’s price), stocks often decrease by the amount of the dividend payment. This shift has an influence on option price. Because the underlying stock’s price is likely to decline in the days running up to the ex-dividend date, call options are less costly.

Simultaneously, the price of put options rises owing to the same projected decline. Investors must grasp the mathematics of option pricing in order to make educated trading choices.

Key Takeaways

  • The payment of dividends affects options listed on equities since holders of the underlying shares get dividends but call and put holders do not.
  • When the underlying stock goes ex-dividend, call options lose value and put options gain as the stock price reflects the dividend to be paid.
  • Deep-in-the-money American-style calls may be exercised prior to the ex-dividend date in order to collect the dividend payment payable to the underlying shares.
  • The Black-Scholes model is unsuitable for evaluating American options on dividend-paying equities.

Stock Price Drop on Ex-dividend Date

The record date is the company’s cut-off date for receiving a dividend. To be eligible for the dividend, an investor must hold the shares by that date. Other regulations, however, apply.

If an investor purchases the shares on the record date, the dividend is not paid. This is because a stock transaction takes two days to settle, which is known as T+2. It takes time for the exchange to process the papers necessary to complete the transaction. As a result, the investor must hold the shares prior to the ex-dividend date.

As a result, the ex-dividend date is critical. All else being equal, the stock price should fall by the amount of the dividend on the ex-dividend date. Because the corporation is forfeiting that money, its value has decreased because the money will soon be in the hands of someone else. Everything else does not stay constant in the actual world. While the stock should theoretically decline by the amount of the dividend, it might increase or fall considerably more since various variables, not only the dividend, influence the price.

Limit orders are sometimes changed by brokers to meet dividend payments. Using the same scenario, if an investor had a limit order to purchase ABCInc. shares at $46, and the business was paying a $1 dividend, the broker may adjust the limit order to $45. Most brokers provide a setting you may use to take advantage of this or to signal that the investor wishes the orders to remain unchanged.

The Impact of Dividends on Options

The ex-dividend date affects both call and put options. Put options become more costly when the price falls by the dividend amount (all else being equal).Call options become cheaper when the stock price falls, albeit for options, this may begin to be priced in the weeks preceding up to the ex-dividend date. To understand why puts rise in value and calls fall, consider what occurs when an investor purchases a call or put.

Put options increase in value when the price of a stock falls. A stock put option is a financial contract in which the holder has the right to sell 100 shares of stock at the stated strike price until the option expires. If the option is exercised, the writer or seller is obligated to purchase the underlying stock at the strike price. For assuming this risk, the seller receives a premium.

Call options, on the other hand, lose value in the days running up to the ex-dividend date. A call option on a stock is a contract that gives the buyer the right to purchase 100 shares of the stock at a set strike price until the option expires. Because the stock price falls on the ex-dividend day, the value of call options falls in the period before the ex-dividend date.

The Black-Scholes Formula

The Black-Scholes formula is a mechanism for pricing options. The Black-Scholes formula, on the other hand, solely represents the value of European-style options that cannot be exercised before the expiry date and do not provide a dividend. As a result, when used to assess American options on dividend-paying equities that may be exercised early, the method has limits.

In practice, stock options are seldom exercised early owing to the loss of the option’s remaining time value. Investors should be aware of the Black-Scholes model’s limitations when assessing options on dividend-paying equities.

The following factors are included in the Black-Scholes formula: the underlying stock price, the strike price of the option in question, the period until the option expires, the implied volatility of the underlying stock, and the risk-free interest rate. Because the calculation does not account for the effect of dividend payments, several experts have devised workarounds. One popular way is to deduct the deferred value of a future dividend from the stock price.

The formula as an equation is as follows:

C = S t N ( d 1 ) K e r t N ( d 2 ) where: d 1 = ln S t K + ( r + σ v 2 2 ) t σ s t and d 2 = d 1 σ s t where: C=Callpremium S=Currentstockprice t=Timeuntiloptionexercise K=Optionstrikingprice N=Cumulativestandardnormaldistribution e=Exponentialterm σ s = Standarddeviation ln=Naturallog \begin{aligned} &C=S_tN\left(d_1\right)-Ke^{-rt}N\left(d_2\right)\\ &\textbf{where:}\\ &d_1=\frac{\ln{\frac{S_t}{K}}+\left(r+\frac{{\sigma_v}^2}{2}\right)t}{\sigma_s\sqrt{t}}\\ &\text{and}\\ &d_2=d_1-\sigma_s\sqrt{t}\\ &\textbf{where:}\\ &\text{C = Call premium}\\ &\text{S = Current stock price}\\ &\text{t = Time until option exercise}\\ &\text{K = Option striking price}\\ &\text{N = Cumulative standard normal distribution}\\ &\text{e = Exponential term}\\ &\sigma_s=\text{Standard deviation}\\ &\text{ln = Natural log}\\ \end{aligned} ​​

The implied volatility in the calculation is the underlying instrument’s volatility. Some traders feel that implied volatility is a better indication of an option’s relative value than price. Traders should also examine the implied volatility of a dividend-paying stock option. The greater a stock’s implied volatility, the more probable its price will fall. As a result of the price reduction, the implied volatility on put options is greater leading up to the ex-dividend date.

  Circumventing the Limitations of Black-Scholes

Many Dividends Cause Barely a Flutter

While a large payout may have an impact on the stock price, several smaller dividends will scarcely move the stock price or option price. Consider a $30 stock that pays a 1% dividend per year. This translates to $0.30 per share, with quarterly payments of $0.075 per share. All else being equal, the stock price should fall by $0.075 on the ex-dividend date. Put options will gain somewhat in value, while call options will lose slightly.

Despite this, certain stocks may easily move 1% or more in a single day based only on trading activity. As a result, the stock might climb on the day even if it should officially open down. As a result, trying to forecast micro-movements in stock and option prices based on dividends may result in missing the wider picture of what is going on with stock and option prices in the days and weeks leading up to the event.

The Bottom Line

Put options will rise somewhat ahead to a dividend, while call options will decline slightly. This presupposes that everything else stays constant, which is not the case in reality. Options will begin pricing the stock price adjustment (due to the dividend) far before the stock price adjustment happens. This suggests that micro-movements in option prices over time are likely to be swamped by other variables. This is particularly true for tiny dividend payments, which represent a fraction of the share price. Significant payouts, such as high-yield distributions, will have a greater influence on share and option prices.
