When a stock changes shape: splits, bonuses and buybacks
The answer
A corporate action is a change a company makes to its own shares. Some of them change only the number of slices your ownership is cut into. Others move real money in or out of the company, and change how much of it you own.
Splits and bonus issues are the first kind. Buybacks, rights issues and follow-on offers are the second kind. Everything in this article is about telling them apart in 10 seconds.
Why this costs you money
Here are 3 losses that happen every year, all from the same confusion.
One. A stock you hold goes from ₹2,000 to ₹1,000 overnight. You panic and sell. It was a 1:1 bonus issue. You now hold twice as many shares, so nothing happened to your money. You sold a holding you wanted to keep, paid brokerage, and possibly paid tax on the gain.
Two. A company you hold announces a rights issue. That is an offer to existing shareholders to buy new shares at a discount. The email goes to your spam folder. You do nothing. New shares are created, you did not buy any, and your percentage of the company falls. You did not lose money in a single day. You lost it quietly, in a line item you never saw.
Three, and this is the expensive one in India right now. A company announces a buyback and you tender your shares into it. You assume the money is a capital gain. Since 1 October 2024 it is not. The whole amount you receive is treated as a dividend and taxed at your income tax slab rate. If you are in the 30% bracket, a payout you expected to be lightly taxed is now taxed heavily. Many investors found this out after they had already tendered.
How it works
Every corporate action has a record date. That is the single day on which the company reads its register of shareholders. If your name is on the register that day, you are entitled. If it is not, you are not. Nothing else matters — not how long you held it, not when you applied.
Before the record date sits the ex-date. From the ex-date onwards, the stock trades without the entitlement. Buy on the ex-date and you do not get it. In India, under the current T+1 settlement cycle, the ex-date and the record date are the same day. So the last day to buy and still qualify is 1 trading day before the record date.
Now the 5 actions.
| Action | New shares created? | Does the company receive or pay money? | Your % of the company |
|---|---|---|---|
| Stock split | No, existing shares are subdivided | No | Unchanged |
| Bonus issue | Yes, from reserves | No | Unchanged |
| Rights issue | Yes | Receives | Falls unless you subscribe |
| Follow-on offer (FPO) | Usually yes | Receives, if fresh shares | Falls |
| Buyback | No, shares are cancelled | Pays | Rises if you do not tender |
A stock split cuts each existing share into smaller pieces. In India, a share with a face value of ₹10 becomes 5 shares with a face value of ₹2 each. In the United States a split is described as "10-for-1", meaning you get 10 shares for each 1 you held.
A bonus issue creates genuinely new shares and gives them to existing holders in proportion. The company pays for them by moving money from its reserves into share capital. That is an accounting entry inside the company. No cash leaves and no cash arrives. A "1:1 bonus" in India means 1 new share for every 1 you hold, so your count doubles and the price halves.
Split and bonus produce the same result for you: more shares, proportionally lower price, identical total value. The difference is legal, not economic.
A rights issue is the company asking you for money. It offers you the right to buy new shares below the market price, in proportion to what you hold. You have 3 options: subscribe, sell the right itself, or do nothing. Doing nothing is the only one that guarantees a loss, because the discount expires.
A follow-on public offer is a listed company selling more shares to the whole public, not only to existing holders. If the shares are new, the company gets the money and your percentage falls.
A buyback is the reverse of an issue. The company uses its own cash to buy its own shares back and cancels them. The share count falls. If you did not sell, you own a slightly larger fraction of a company holding slightly less cash.
What it tells you, and what it does not
A split or bonus tells you almost nothing about value. Management chose to change the slice size. That is all that happened. There is one weak signal inside it: boards prefer not to split just before bad news, so a split is mild evidence that management is not expecting a collapse. It is mild. Companies have split their stock and then fallen 80%.
A buyback tells you something real, and it is easy to over-read.
What a buyback genuinely says: the company has cash, it has no project it likes better than its own shares, and the board is willing to say so publicly.
What a buyback does not say:
- That the shares are cheap. Boards buy at high prices routinely. Many large US companies bought heavily in 2021 and stopped in 2022, which is the opposite of buying low.
- That the share count will fall. Many companies buy back shares only to cancel out the new shares they issue to employees. The count stays flat while the cash leaves. The announcement is not the number. The share count over 5 years is the number.
- That the money was spare. Buybacks can be funded with borrowed money. Then the company has fewer shares and more debt.
The decision rule
Sort every corporate action into 1 of 2 boxes before you react.
Box 1 — the cake is being re-sliced. Split, bonus. Your share count changes, the price changes, your money does not. Do nothing. Check that your broker adjusted the average buy price, and move on.
Box 2 — money is crossing the company's boundary. Rights issue, FPO, buyback. Cash is entering or leaving the business, and your percentage of it is about to change. This needs a decision and a date in your calendar.
The single question that puts an action in the right box: did cash move between the company and its shareholders? If no, it is cosmetic. If yes, it is real.
Try this now
Five minutes, on your own holdings. You need 1 stock you have held for more than a year.
- Open your broker app and find Corporate Actions, Company Actions or Portfolio history. In India you can also use the free monthly statement from CDSL or NSDL, or the Corporate Actions page for that stock on the NSE or BSE website. In the United States, look under Account history.
- Find any split, bonus issue or buyback that happened while you held the stock. Write down the record date.
- For a split or bonus: compare your share quantity and your average buy price before and after. Multiply quantity by average price in both cases.
- For a buyback or dividend: open your trade history and find the date you bought. Was your purchase settled and in your demat account before the record date? That is the only test of eligibility.
What you should see. For the split or bonus, quantity went up and average price came down by exactly the same ratio. Quantity multiplied by average price is the same number before and after, to the rupee or the cent. Your broker did not give you anything and did not take anything away.
For the buyback you learn something more useful: whether you were eligible at all. Many investors buy 2 days before a record date, miss the settlement, and never understand why they were left out. The record date is a photograph of the register on 1 morning.
Three real cases
1. NVIDIA, June 2024 (United States) — a split changes nothing, and looks like it changes everything NVIDIA split its stock 10-for-1, effective 10 June 2024. A holder of 1 share held 10 the next morning, each priced at roughly one-tenth of the previous price. Revenue, chips, customers and market value were untouched. Coverage described the stock as "more accessible", which was true, and as "cheaper", which was not.
2. Reliance Industries, October 2024 (India) — 1:1 bonus, and the halved screen price Reliance issued bonus shares in the ratio 1:1, with a record date of 28 October
- Every holder of 1 share held 2, and the quoted price fell by about
half overnight. Nobody lost anything. The company moved money from reserves into share capital, which is 1 row of the balance sheet moving into another.
3. Tata Consultancy Services, November 2023, and the tax change 10 months later (India) — the same action, taxed 2 completely different ways TCS bought back shares at ₹4,150 each through a tender offer, for about ₹17,000 crore, with a record date of 25 November 2023. Under the rules then, the company paid a buyback distribution tax of 20% plus surcharge, and the money the shareholder received was exempt. From 1 October 2024 the Finance (No. 2) Act 2024 reversed this. The company pays nothing, and the shareholder is taxed on the full amount as a deemed dividend at slab rate. Indian buyback announcements fell after that date. The corporate action did not change. Only the tax did, and that was enough to change company behaviour.
The question that resolves it
A novice sees the price of their holding fall by half and asks: how much did I lose?
An expert asks: did my share count change on the same day?
If the count changed in the opposite direction by the same ratio, nothing happened. If the count did not change, something did.
What would make this wrong
If splits and bonus issues created value, then a company could make its shareholders richer by repeating them. It cannot. The price adjusts on the ex-date by the exact ratio, on every exchange, automatically. That is not a theory. It is an arithmetic operation the exchange performs.
The honest limits:
Research does find small, real effects around split announcements — better liquidity, a modest positive price drift, more retail holders. These are second-order and they are not a reason to buy a stock.
Buybacks are harder. Companies that buy back shares when they are cheap create value. Companies that buy at peak prices destroy it. You cannot tell which one you are looking at from the announcement. You can only tell later, from the share count and the price paid.
A rights issue is not automatically bad news either. A bank raising regulatory capital and a failing company raising money to survive use the same instrument. The instrument tells you nothing. The Objects of the Issue section tells you a great deal.
In India
Face value and splits. Indian shares carry a face value, usually ₹10, ₹5, ₹2 or ₹1. A split changes it. A bonus does not. If the face value changed, it was a split.
Bonus share credit. SEBI reduced the timeline so bonus shares are credited and tradable on T+2 from the record date, for record dates on or after 1 October 2024. Before that the gap could run to 2 weeks, during which holders saw a halved price and no extra shares. That gap caused a lot of unnecessary panic.
Rights issues. Your entitlement is credited to your demat account as a Rights Entitlement, with its own ISIN, and it trades on the exchange for a few days. So the third option is real: if you do not want to put in more money, you can sell the entitlement instead of letting it lapse. SEBI has also compressed the rights issue timeline sharply, to around 23 working days from board approval.
Buybacks. Two routes exist. A tender offer buys a fixed number of shares at a fixed price from shareholders who apply, with 15% of the buyback reserved for small shareholders — those holding shares with a market value up to ₹2 lakh on the record date. An open market buyback buys shares on the exchange over time, at market prices, with no guarantee any individual holder is included. SEBI has been phasing out the open market route. Company law limits apply: a buyback cannot exceed 25% of paid-up capital and free reserves .
Tax. For buybacks with a record date on or after 1 October 2024, the entire amount you receive is taxed as a deemed dividend at your slab rate, and the cost of the shares you tendered becomes a capital loss you can set off against capital gains. Verify this against the current Act before you tender. India replaced the Income-tax Act 1961 with the Income-tax Act 2025, and section references have moved.
FPOs. Vodafone Idea raised about ₹18,000 crore through a follow-on public offer in April 2024, the largest FPO in India at the time. That is the same instrument as an IPO, used by a company that is already listed.
In the United States
Splits and reverse splits. Splits work identically. Reverse splits matter more here, because both the NYSE and the Nasdaq require a share price above $1.00 to stay listed. A company drifting under $1 does a reverse split — for example 1-for-10 — to lift the quoted price back over the line. Citigroup did exactly this, 1-for-10, in May 2011. A reverse split is usually a symptom, not a cure.
Rights issues are rare. US companies raise follow-on capital mostly through secondary offerings sold to institutions. So the "check your email or lose money" risk is much smaller for a US investor.
Buybacks are enormous. They are the main way large US companies return cash. The reason is partly tax: a dividend is taxed when it is paid, whether you want the money or not, while a buyback lets each shareholder choose when to sell and therefore when to be taxed.
Two rules shape how they are done.
- Rule 10b-18 gives a company a safe harbour from market manipulation charges if it buys within limits on volume, timing, price and number of brokers — including a daily volume cap of 25% of average daily trading volume
. It is a safe harbour, not an obligation.
- A 1% excise tax on the net value of shares repurchased, introduced by the Inflation Reduction Act of 2022, applies to repurchases made after 31 December
- It is paid by the company, not the shareholder.
The SEC also adopted a rule in 2023 requiring far more detailed daily buyback disclosure. A federal appeals court vacated it in December 2023, so US buyback disclosure remains less granular than the Indian equivalent.
Where they differ, and what that tells you
The interesting divergence is not the mechanics. It is the tax.
- United States: the company pays a 1% excise tax. The shareholder is taxed only if they choose to sell, and then on the gain, not on the whole amount.
- India before 1 October 2024: the company paid roughly 20% plus surcharge, and the shareholder received the money tax-free.
- India from 1 October 2024: the company pays nothing, and the shareholder is taxed on the entire amount received, not the gain, at slab rate
.
What this tells you is that a buyback is not one thing. It is a corporate action wrapped in a tax rule, and the tax rule decides whether it is good for you. The same announcement from the same company means "cash returned efficiently" in one country and "cash returned to a 30% taxpayer at 30%" in another.
The practical consequence for an Indian investor is direct. Do not judge a buyback offer by the premium alone. Compare the after-tax amount you keep to what you would keep by selling in the market and paying capital gains tax. Since October 2024 the market sale is often better for a high-slab investor, even at a lower price.
Carry this
- Split and bonus: the cake is re-cut. Your money did not move.
- Rights, FPO and buyback: cash crossed the company's boundary. This needs a decision.
- The record date is a photograph. Be on the register before it, or you are not in it.
