Why Does a Stock Drop on the Ex-Dividend Date?
A stock's drop on the ex-dividend date is the dividend leaving the share price and arriving in your account. Nothing is lost at the open, though the price chart makes it look that way.
Short answer
The dividend is cash leaving the company, so each share is worth about that much less once it's paid out. From the ex-date on, buyers no longer get the payment, so they pay roughly the dividend less for the shares, and the price usually opens lower by about that amount.
A position that opens $1.00 a share lower on the ex-date, on a $1.00 dividend, hasn’t lost anything. The price screen shows red. Your account, once the dividend is counted, is about where it was the night before.
Where does the dollar go?
Out of the company. A dividend is cash the company pays to its shareholders, and once it’s committed to paying it, that cash no longer belongs to the business. A share is a claim on what the company owns, so when a dollar per share leaves the business, whether it was sitting in the bank or would have paid for next year’s plans, the claim is worth about a dollar less than it was the day before.
The ex-date is when the market prices that in. Before it, a share comes with the right to the coming payment. From the ex-date on, it doesn’t. Anyone buying on the ex-date is buying a share without the dividend attached, so they pay less for it, by roughly the amount they won’t receive. The ex-dividend date is the line between those two versions of the same share.
How big is the drop?
About $49. The word “about” matters. The arithmetic gives a reference point, and the actual opening price is set by buyers and sellers who are also reacting to everything else that happened overnight.
Why is the drop rarely exact?
Other things move the price the same morning. The whole market may be sliding, or the company may have put out news before the bell. Either can push the open well above or below $49, and on a volatile morning the dividend is a small part of the move.
Small dividends make the effect hard to see at all. A stock yielding a modest amount pays a few cents a share each quarter, and a few cents disappears inside an ordinary day’s range. Large dividends, and above all special dividends, make the drop easier to spot. Unusually big special dividends can also come with their own ex-date convention.
So the rule holds on average. On any single morning it’s a starting point, with the rest of the market layered on top.
Does the price climb back?
Sometimes. Nothing about the dividend makes a recovery due. A stock that has gone ex-dividend is worth less for a plain reason, and whether it regains the $1.00 over the following days or weeks depends on the same things that move it on any other day, from earnings to the direction of the whole market, which is why a chart showing the price back at $50 a week later tells you about that week and nothing about the dividend.
What does the drop mean for your return?
At the open, very little. Price change plus dividend comes to roughly zero.
That’s why buying just before the ex-date to collect the payment doesn’t produce free money. You pay for the dividend in the share price and get it back as cash, and in a taxable account that cash is taxed, at the ordinary rate if you held too briefly to pass the IRS holding test. The fuller case is in dividend capture rarely survives the ex-date. If you’re wondering who gets the payment when shares change hands around that day, whether you get the dividend if you sell on the ex-date walks through each case.
One point on charts. Many charting tools offer a dividend-adjusted view that smooths out ex-date drops. The unadjusted chart shows them as small gaps down, which can be mistaken for selling.
How do options handle the drop?
Strike prices don’t change for regular dividends. A $50 call is still a $50 call after the stock goes ex-dividend. So the market builds the expected dividend into option prices ahead of time, and a known dividend before expiration pulls call prices lower and pushes put prices higher than they’d be with no dividend, because everyone can see the stock will open lower by roughly that amount on the ex-date.
Large special dividends can be different. The OCC may adjust the contract terms for those. Your broker will post a notice when it does.
Standard pricing models subtract the value of expected dividends from the stock price before they work out what an option is worth, so the dividend is already inside the quote on your screen. If a company changes its dividend unexpectedly, option prices shift to match.
If you hold covered calls, check the ex-dates on your underlying stocks against your expirations. The options topic hub covers how dividends fit into the rest of option pricing.

Do open orders change on the ex-dividend date?
Some can. Under a FINRA rule, certain resting orders such as buy limits and sell stops are reduced by the dividend amount on the ex-date unless they're marked do not reduce. Brokers handle this differently, so check how yours treats open orders.
Does the stock price recover after the ex-dividend date?
Sometimes, with no schedule to it. The drop reflects cash that has left the company, so nothing makes the price due to climb back. Whether it regains the amount over the following days depends on earnings, news and the direction of the market, the same forces that drive it the rest of the year.
