Ex-date, stock split, and buyback: events that do not always mean what you think
You open your investment account and see a 5% fall with no dramatic news. Another share you considered buying suddenly moves from ₪20 to ₪200. Or a company announces that it will buy billions of shekels of its own shares.

The first human reaction is to assume that something enormous has happened—that the company is collapsing, soaring, or handing you free gifts. In practice, the change on the screen is often only technical or accounting-based and does not reflect a change in the company’s economic value.
Here is a quick roadmap to these technical market changes:
Quick roadmap
| Market event | What actually changes? | What does not change? |
|---|---|---|
| Ex-date | The right to receive the upcoming dividend is separated from a new buyer’s purchase. | Your total value—the share plus the cash you will receive—has not really fallen as the chart suggests. |
| Stock split | The number of shares increases and the price of each share falls proportionally. | Your ownership percentage and the total value of your holding. |
| Reverse stock split | The number of shares decreases and the price of each share rises proportionally. | The company’s economic value; this is often only a cosmetic move. |
| Share buyback | The company uses its cash to buy and remove its own shares. | The move does not automatically benefit you; that depends entirely on the purchase price. |
Ex-date: the share fell—but perhaps you received cash
Suppose Alpha shares trade at ₪100 and the company decides to distribute a dividend of ₪5 per share.
Anyone who holds the share on the record date is entitled to receive the ₪5 into their account on the payment date. But what happens the next day, on the ex-dividend date? From that date onward, a buyer purchases the share without the right to receive the upcoming dividend.
Because the company physically removed ₪5 from its cash and transferred it to shareholders, the company is now worth less. The exchange therefore adjusts the share price downward at the opening of the ex-date:
- Before the ex-date: A share worth ₪100, including the right to ₪5 in cash.
- On the ex-date: The share price is technically adjusted to ₪95.
The common mistake: believing a dividend is “free money”
Many beginning investors try to outsmart the system by buying a share one day before the ex-date solely to capture the dividend and sell the next day.
The tactic fails for two reasons. First, the share price falls by the distribution amount on the ex-date, so the sale loss offsets the dividend. Second, tax is generally withheld from the dividend—usually 25% for an Israeli individual investor. You may therefore buy an asset, pay tax on the distribution, and be left with less money.
A dividend is an excellent way to transfer cash to investors, but it does not create money out of nothing.
Stock split: you have more shares, but you are not richer
Suppose you own 100 shares of a company and each is worth ₪100. Your total holding is worth ₪10,000. The company carries out a two-for-one stock split. What happens the next morning?
- Number of shares: It doubles to 200.
- Price per share: It halves to ₪50.
- Total value of your holding: It remains exactly ₪10,000.
Why does a company split its shares?
One reason may be that the share price has become very high and the company wants to make the unit price more accessible and convenient for trading.
A share priced at ₪500 can become five shares with a theoretical price of ₪100 each after a five-for-one split.
But the split itself did not improve profits, put cash into the company, or make the business better.
The market may sometimes become excited by the announcement and the share may rise, but that is a psychological reaction by buyers, not new economic value created inside the business.
Reverse stock split: fewer shares, a higher price
A reverse stock split is the exact opposite of a stock split.
Suppose you own 1,000 shares worth ₪1 each—a total value of ₪1,000. The company carries out a one-for-ten reverse split.
- After the consolidation: You have only 100 shares, but each is displayed at ₪10.
- Value of your holding: It remains ₪1,000.
Why can a reverse split be a warning sign?
A stock split usually comes from a successful company whose share price has risen. A reverse split often comes from a company in difficulty. In many markets, including the United States, a share that remains below one dollar may face delisting. Companies may use a reverse split as an urgent cosmetic measure to raise the displayed price and meet listing requirements.
Ask:
Why is the company carrying out the reverse split now?
Share buyback: when a company buys its own shares
Unlike splits and reverse splits, which are only technical, a share buyback is a real economic event. The company takes actual cash and buys its shares in the open market, then cancels or holds them.
How does this affect you? Suppose the company has one million shares outstanding and you own 10,000—1% of the company. If the company buys and removes 200,000 shares, only 800,000 remain. Your 10,000 shares now represent 1.25% of the company. Without investing another shekel, your share of the business’s future profits has grown.
A buyback is often viewed as a positive signal: management expresses confidence in the business and believes the share is trading cheaply. If the company’s profit remains unchanged but is divided among fewer shares, earnings per share—EPS—rises mathematically.
The trap: a company can buy itself at an excessive price
If management uses billions of shekels to buy shares at an inflated all-time high, it destroys value for shareholders. The money might have been better invested in research and development, used to repay debt, or distributed as a dividend.
What should you actually examine in a buyback?
Do not stop at the announcement of a buyback program
- Is the share count actually falling? Many companies announce a “share buyback program” while granting large packages of options and restricted shares to managers and employees. The buyback may merely offset employee dilution, with no real fall in the total share count.
- How much money was authorized? How many shares were actually purchased, and at what price?
Do not examine only what the company announced it planned to do. Examine what actually happened.
The most common mistake
The greatest mistake is treating the price of one share as if it tells the whole story. The share price is only a numerator; it must always be assessed against the denominator—how many shares exist and the company’s total value. When the screen displays a dramatic movement, do not ask only “What happened to the price?” Ask: “What actually changed in the company and in my economic rights?”
- Did the share fall on the ex-date? You may have received a dividend.
- Did the price double after a reverse split? You did not become twice as rich.
- Did your share count double in a split? The value of your holding did not double.
- Did the company announce a buyback? You still need to check whether it executed the program and at what price.
The bottom line
The ex-date, a stock split, a reverse stock split, and a share buyback can create movements and numbers that look dramatic on the screen.
But not every price change is a real gainThe actual gain remaining from an investment after deducting the rate of inflation. or loss.
On the ex-date, part of the value moved from the company to its shareholders.
In a split or reverse split, the main change is the number of units.
In a buyback, the company uses cash to reduce the number of shares—a move that may be good or bad depending on the price and circumstances.
