Ex-Dates, Stock Splits, and Buybacks: Share Events That Aren’t Always What They Seem
You open your investment account and are shocked: your share is down 5% at the market open, with no dramatic news. Another day, a share you considered buying for 20 NIS suddenly costs 200 NIS. Or a major company you own proudly announces that it is starting to buy back its own shares for billions of shekels.

The first human reaction is to think that something huge has happened—that the company is collapsing, soaring, or giving you free gifts. In practice, in most cases the change you see on the screen is purely technical and accounting-related and does not reflect a change in the company's economic value.
To bring some order to this, let's start with a quick roadmap of technical market changes:
The Quick Roadmap
| Market event | What actually changes? | What does not change (and does not affect your wealth)? |
|---|---|---|
| Ex-dividend date (Ex-Date) | The right to receive the upcoming dividend transfers from the new buyer to the current shareholder. | Your total value (the stock plus the cash you will receive) has not really fallen as much as the chart suggests. |
| Stock Split | The number of shares increases, and the price of each individual share falls accordingly. | Your ownership stake in the company and the total value of your holding. |
| Reverse Split | The number of shares decreases, and the price of each individual share rises accordingly. | The company's economic value (often, this is merely a cosmetic move). |
| Buyback | The company uses its cash to buy and retire its own shares. | The move does not automatically benefit you—it depends entirely on the price the company paid. |
Ex-Date: The Stock Fell—But You May Have Received Cash
Suppose shares of company "Alpha" trade at 100 ILS, and the company decides to distribute a dividend of 5 ILS per share.
Anyone holding the share on the record date is entitled to receive these 5 shekels directly into their bank account on the payment date. But what happens the next day, on what the exchange calls the "ex-date" (Ex-Dividend Date)? From that day onward, anyone buying the share is buying it "clean"—that is, without the right to receive the upcoming dividend.
Because the company physically took 5 ILS from its cash reserves and transferred it to you, the company itself is now worth less. Therefore, the exchange automatically adjusts the stock price downward at the opening of the ex-date:
- Before the ex-date: A share worth 100 ILS (which includes the right to 5 ILS in cash).
- On the ex-date: The share price is technically adjusted to 95 ILS.
The Common Mistake: Thinking a Dividend Is "Free Money"
Many beginner investors try to "game" the system: they buy a stock the day before the ex-date just to "capture" the dividend and sell it the next day.
This tactic fails for two reasons: first, the stock price falls by the amount of the distribution on the ex-date, so you sell at a loss that offsets the gain. Second, you will usually pay withholding tax on the dividend you received (typically 25% for a private investor in Israel). This means you bought an asset, paid tax on it, and were left with less money in hand.
A dividend is an excellent tool for transferring cash to investors, but it never creates money out of thin air.
Stock Split: You Have More Shares—But You Are Not Richer
Suppose you hold 100 shares in a company, with each share worth 100 ILS. Your total holding is worth 10,000 ILS. The company decides to carry out a stock split at a ratio of 1-for-2. What happens the next morning?
- Your number of shares: It will double to 200 shares.
- The share price on the screen: It will be cut in half to 50 ILS.
- Your total holding value: It remains exactly the same—10,000 ILS.
So Why Would a Company Split Its Shares?
One reason may be that the stock price has become very high, and the company wants to make the per-share price more accessible and convenient for trading.
A stock priced at 500 ILS can become, after a 1-for-5 split, five shares at a theoretical price of 100 ILS each.
But it is important to understand: the split itself did not improve profits, put money into the coffers, or make the business better.
Sometimes the market gets excited by the announcement and the stock rises—but that is a psychological reaction from buyers, not real economic value created within the factory or business.
Reverse Split: Fewer Shares, Higher Price
A reverse stock split is exactly the opposite of a stock split.
Suppose you have 1,000 shares worth one shekel each (total value: 1,000 ILS). The company carries out a 10-for-1 reverse split.
- After the reverse split: You will have only 100 shares, but the price of each will rise on the screen to 10 ILS.
- The value of your holding: Remains 1,000 ILS.
So Why Does a Reverse Split Sometimes Raise a Red Flag?
While stock splits usually come from successful companies whose share price has climbed high, reverse splits usually come from companies in difficulty. In many markets (such as the U.S.), if a stock price remains below one dollar for an extended period, it is at risk of being delisted. Companies use reverse splits as an urgent cosmetic move to artificially boost the share price and meet the minimum requirements.
Therefore, it is worth asking:
Why is the company carrying out the reverse split now?
Buyback: When the Company Buys Its Own Shares
Unlike splits and reverse splits, which are purely technical moves, a buyback is a real economic event. In a buyback, the company takes real money from its cash reserves and uses it to buy its own shares on the open market, then "cancels" them or holds them as treasury shares.
How does this affect you? Suppose a company has one million shares on the market, and you hold 10,000 shares—meaning you own 1% of the company. If the company buys and retires 200,000 shares from the market, only 800,000 active shares remain. Your 10,000 shares now represent 1.25% of the company. Without investing another shekel, your share of the business's future profits increases.
A buyback is viewed by the market as a very positive sign—management expressing confidence in its own business and believing the stock is trading at a cheap price (a discount). If the company's profit remains constant but is divided among fewer shares, earnings per share (EPS) rise mathematically and push the valuation upward.
The Trap: A Company Can Buy Itself at an Expensive Price
A company can buy back its own shares at too high a price. If management uses billions of shekels to buy shares at an all-time high and at inflated prices, it destroys value for you. That money would be better invested in research and development, paying down debt, or simply distributed to you as a dividend.
What should you really examine in a share buyback?
Do not settle for the announcement of a buyback program
- Is the number of shares actually declining? Many companies announce a “share buyback program” while simultaneously granting huge packages of options and restricted shares to their executives and employees. In that case, the buyback merely offsets employee dilution, and the total number of shares on the market does not actually decrease.
- How much money was authorized? How many shares were actually repurchased, and at what price?
Do not look only at what the company said it planned to do. Check what actually happened.
The most common mistake
Investors’ biggest mistake is viewing the price of a single share as if it were everything. A share price is only the numerator; it must always be considered against the denominator—how many shares exist in the market and what the company’s total value is. When the screen shows dramatic fluctuations, do not ask only, “What happened to the price?” Ask: “What actually changed economically in the company and in my rights?”
- Did the share fall on the ex-date? Perhaps you received a dividend.
- Did the share price double after a reverse split? You did not become twice as rich.
- Did your number of shares double in a stock split? The value of your holding did not double.
- Did the company announce a buyback? You still need to check whether it actually carried it out and at what price.
The bottom line
The ex-date, stock splits, reverse splits, and share buybacks can create movements and figures that look dramatic on 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 shareholders.
In stock splits and reverse splits, it is mainly the number of units that changed.
In a share buyback, the company uses money to reduce the number of shares—a move that can be good or bad, depending on the price and circumstances.
